AV Stumpfl SHIFT screen legs are designed to make positioning professional mobile projection screens faster, easier, and more precise. Available in T32-SHIFT and AT64-SHIFT configurations, the system allows a fully assembled projection screen to be raised or lowered without first disassembling the frame. A clearly marked height scale provides precise adjustment in 1-inch increments, eliminating the need for additional measuring during setup. As the screen is raised, the SHIFT mechanism automatically locks into position. Lowering the screen is just as straightforward using the integrated release mechanism. SHIFT legs are compatible with AV Stumpfl mobile projection screen systems and are engineered with robust components for repeated use in rental, staging, corporate AV, and live production environments. Their modular design also allows the legs to be configured at different lengths depending on the screen size and required installation height. The T32-SHIFT system offers mounting heights from approximately 2 to 49 inches and can be assembled in four different leg lengths. For larger applications, the AT64-SHIFT provides mounting heights from approximately 3.5 to 76.5 inches and can be configured in eight different lengths.

When you’re setting a projection screen on-site, getting the frame built is only half the battle. Getting it to exactly the right height, while keeping everything level and secure, is where the AV Stumpfl SHIFT system really earns its place in a production kit.

The biggest advantage is simple: you can adjust the screen after it is already assembled.

That means your crew isn’t tearing a screen apart because the bottom edge needs to come up another six inches. With clearly marked height references and fine adjustment in one-inch increments, it becomes much easier to match sightlines, stage layouts, projector placement, scenic elements, or multiple screens across a room.

For rental and staging companies, that saves real time during load-in. It also reduces the amount of measuring, rebuilding, and trial-and-error involved when conditions on-site don’t exactly match the drawing.

We especially like SHIFT legs for environments where screen height may need to change from one setup to another. Corporate ballrooms, breakout rooms, general sessions, live events, and temporary installations rarely behave exactly the same from venue to venue. Having a screen support system that can adapt quickly gives your crew more flexibility without introducing more complexity.

The result is one of those upgrades that feels small until you’ve used it on a real show. Faster adjustment, fewer headaches, and one less reason to rebuild something you’ve already finished.
