The A-Frame is a core building block of the AV-Drop modular system. Two A-Frames can be joined to build a compete frame or can be extended in height and/or width by using extensions to create additional sizes. The frames are connected with an UP (Union Piece.) The come in 4’ and 5’ heights and each height is available in 4’, 3’, 2’, 1.5’ and 1’ widths.
AV-Drop frames for angled sets, available in stock degree configurations of 75°/105° and 60°/120°. Additional sets include 45°/135° and 30°/150°. Custom Angles may also be available for specific projects.
The ratio of an image’s width to it is height. It is commonly expressed as two numbers separated by a colon, as in 16:9. For an x:y aspect ratio, the image is x units wide and y units high. Widely used aspect ratios include 1.85:1 and 2.39:1 in film photography, 4:3 and 16:9 in television, and 3:2 in still camera photography. Today, 16:9 is the most common ratio.
Scenic element behind a speaker or presenter meant to add context and visual interest, often including graphic imagery or branding.
Bracket For Screen. The BFS slides between two frames and has a support bracket extending outwards from the face of the frames. The bracket provides support for a front projection screen or gallery frame. BFS brackets come in multiple extension depths that allow frames to be suspended from the wall on different planes.
Borderless Screen refers to a front surface video projection screen without borders. Typical fast fold style projection screens have black borders surrounding the image area. AV-Drop screens are “Full White” without any borders. The screen is all image area.

Dual Corner Clamps are used to attach AV-Drop frames at a 90-degree angle, such as with a stabilizer or 90-degree corners. They are also used to secure a rear projection screen from behind .
A structure finished with fabric on both sides.
A computer printing technique which uses heat to transfer dye onto materials such as a plastic, card, paper, or fabric. The sublimation name was first applied because the dye was considered to make the transition between the solid and gas states without going through a liquid stage.
Dye Sub printing is used frequently for AV-Drop skins. Prints are available in 128” and 192” wide.
Extensions are a core building block of the AV-Drop Modular System. They are used to extend height or width of the “A”, “F” and other named frames and are connected to the other frames using Union Pieces (UP. ) Standard lengths are 6’, 5’, 4’, 3’ and 2’. Custom sizes are available.
The extrusion is the actual molded form of the frames. The AV-Drop extrusion is designed for maximum rigidity and minimum weight. It is also a manufacturing process used to create objects of a fixed cross-sectional profile. A material is pushed through a die of the desired cross-section. Allows for the creation of complex cross-sections, and to work materials that are brittle, because the material only encounters compressive and shear stresses. It also forms parts with an excellent surface finish.
A core building block of the AV-Drop Modular System. Utilizing Extensions, the “F” frames create panels of heights and widths that are typical higher or wider than A-Frame panels. F- Frames come in 4’ and 5’ heights and are typically used in pairs – one left and one right. Both heights are also only 1’w which allows for greater flexibility when shipping, as the pieces can take up less space on a pallet.
Portable, foldable projection screen system based on leg-to-frame joints. Compatible with AV-Drop for attachment from the rear.
A theatrical flat is a basic building block of scenery used in theatre, film, TV, and live events. Scenery flats are used to create a background and are commonly build of wood and covered in canvas, muslin or other fabrics or custom printed banner material.
FR refers to a fabric that has been treated to be flame retardant per established fire code standards and ratings. Flame retardant fabrics are created by applying flame retardant chemicals. Flame retardant chemicals are dissolved in water and then applied to the fabric through dipping or spraying. When the fabric becomes dry from this process of application, flame retardant chemicals adhere to the fabric fibers which make the fabric Flame Retardant on an impermanent basis. Flame retardant chemicals will be removed when exposed to water, making machine washing or dry-cleaning problematic. Humidity and airborne dust and oils can also diminish the endurance and effectiveness of the flame retardant chemical.
Projection Screen used when image is projected from front of house, rather than behind the set. Offers more flexibility in material than rear projection.
Smaller, hanging sections of AV-Drop, attached to a larger white AV-Drop wall from the front using our BFS brackets, similar to paintings hanging in a gallery.

Scenic element forming top of a set or a surround above a rear projection screen; forms the border for the upper “void” or cutout in the surround. See also Skirt.
IFR refers to a fabric that has been treated to be flame retardant per established fire code standards and ratings. Inherently Flame-Retardant materials have flame retardants built into the fibers so that they become permanently fixed to the material’s structure. By the protection being built into the fiber itself, the flame retardant will not wear or wash away.
The inner skin refers to an AV-Drop the skin that is applied directly to an AV-Drop frame. The inner skin is often used as a blackout layer when a non-opaque outer skin is used. The inner skins can also be a single layer light blocking or printed skin.
Scenic support structure meant to provide counterbalance from the rear. Sits perpendicular to the surface of a piece of scenery, usually weighed down with sandbags for non-permanent installations.
Large format printing medium using water-based inks. Commonly used on outdoor signage, vinyl banners, vehicles and other applications where a degree of water resistance is desired. It works quite well for AV-Drop fabric skins in widths up to 128” (3.2m.)
Less Than Truckload (LTL). Common method of freight shipping for AV-Drop rentals. Individual pallets, usually one per order, are accepted by a carrier for shipment. When shipping LTL, the shipper pays for the portion of a standard truck trailer their freight occupies, while other shippers and their shipments fill the unoccupied space.
Slang, referring to main group of a meeting or conference. See also General Session.
Molton is a popular wide format fabric used extensively in Europe. It is typically 118” wide (3 meters). AV-Drop typically uses black as it would be considered a dim out fabric, not quite 100% blackout, but quite adequate for most applications. However, if there are high ambient lighting conditions behind the frame a secondary blackout skin may be required. Molton has a matte finish and absorbs light and reflections. It is available in several other common colors, including chroma key green.
National Fire Protection Association, NFPA-701 is drapery fabric is tested by burning small samples and then measuring the flame, char length and flaming residue. If a fabric meets the NFPA-701 in these three areas, the fabric is considered flame retardant and receives a NFPA 701 certification. This is the accepted US flame resistance standard that fire department jurisdictions accept as being a minimum standard for fire resistance drape typically used in commercial applications. Note: The State of California has additional certifications and test requirements.
The outer skin refers to an AV-Drop skin used over an inner blackout skin. This is due to the outer skin having some inherent degree of translucency.
In manufacturing, the thickness or basic outer shape of a material. See also extrusion. AV-Drop frames are built of an aluminum extrusion profile.

Standard Clamp. The standard clamp is proprietary clamp meant to hold AV-Drop modules (walls) together from behind the set-in parallel sequence to create a single wall. Clamps to the inner channel of the AV-Drop extrusion from the rear.
A step and repeat is a banner/backdrop, also known as photo call or press wall, used as a publicity backdrop primarily for event video and photography. The name “step and repeat” refers to a repeating printed pattern of logos or graphics typically featured on the structure.
Step and repeat banners are most often seen at red carpet or fashion events. As their familiarity has grown these custom design and printed backdrops are being used for galas, weddings and even corporate events to offer a "celebrity-like," VIP feeling for guest photos.
AV-Drop modular scenic is the perfect solution for broadcast quality backdrops utilizing matte fabric prints.
Lighting or stage truss is typically fabricated from 2-inch round aluminum tubes referred to as chords. Truss sections generally consist of 2, 3 or 4 chords. Two Chord Light truss is often referred to as Ladder Truss, Three Chord Truss are often referred to as Triangle Truss and Four Chords would be a Box Truss. The diagonal members or webbing in the truss is generally a smaller diameter round tube. There are a variety of connections available on the market that provide an array of different strengths and load ratings.
A truss base is an aluminum or steel plate meant to support a piece of truss from the ground. Attaches with nuts and bolts to truss structure.
A truss base weight can be compact mass of recycled rubber, steel or cast iron used for structural counterbalance and support.
Custom length extensions meant to allow for the AV-Drop system to accommodate inch or fractional dimensions beyond the capacity of our normal stock sizes. Useful for creating specific-sized projection screens (example: 6’ x 10’8”) or other irregular sizes. Used in place of a normal UP (union piece) between connections.
Universal Connector for all AV-Drop modules. Made of narrower extrusion to fit inside the main extrusion of an AV-Drop frame. Attaches securely to frame via spring-loaded push-button mechanism. May be made of aluminum or plastic for lighter weight with no reduction in durability.
A form of digital printing that uses ultra-violet lights to dry or cure ink as it is printed. As the printer distributes ink on the surface of a material (called a "substrate"), specially designed UV lights follow close behind, curing - or drying - the ink instantly. Originally developed for quickly drying gel nail polishes during manicures, ultraviolet light applications quickly expanded into industrial and commercial markets. Because the UV lights cure any printed ink immediately, the dots of wet ink do not get a chance to spread out once printed, resulting in much finer detail. In addition, UV cured inks are weather-resistant and offer increased resistance to fading. This curing process is more environmentally friendly as it produces few VOC’s, odor, and heat. UV curing also allows the flatbed printer to be used with nontraditional materials like acrylic or aluminum.
A short section of drape or hard scenery used above a set or stage for masking, especially of lights or cabling. Typical lengths are 1’, 1’6”, or 2’. See also Header.
See Projection Mapping.
The White/Blackout skin is the most common skin fabric used for AV-Drop. White blackout skins utilize a wide format fabric that is typically available in 110” wide raw fabric, making it perfect to build seamless 8’ wide flats. The fabric itself is polyester composition laminated with 3 layers of foam on the back to create the blackout quality.
The fabric itself is not unique to AV-Drop but is commonly used a blackout liner for commercial or residential Drape.
Common textiles are typically woven or knit with finished rolls averaging 48” to 60” wide. Wide Fabrics are 2.8 to 3.2m wide 110”-126” wide. AV-Drop utilizes wide fabrics to make seamless 8’ wide. flats. This is preferred opposed to traditional wooded flats that are 4’ wide or need to join or have twice as many seams every 4”.
A term used for the left and right drape flat of the screen area. Wings are also the area to the left and right of a stage are typically out of site from the audience.
