Lightweight. Solid. Base.

We do offer different types of legs and other mounting options for our projection screens to perfectly meet our customer requirements. Our projection screen legs feature the same precision and life time like our frames. No matter why: They are made out of the same components using the same manufacturing techniques.

Standard Legs

Height adjustment in steps of 6“ (152,4mm)

compatible with all mobile AV Stumpfl screen systems

When a high degree of stability is needed, especially with large screens or a high set-up height, we recommend using following legs: AT32 for MONOBLOX 32 and AT48 or AT64 for MONOBLOX 64. AT-Legs have a telescopic support that is tightened with two wing screws.


SHIFT Technology


The truly revolutionary SHIFT screen system legs make it possible to easily adjust a mobile projection screen‘s height, without having to disassemble it first. No extra measuring is needed to ensure the frame is level, due to a clearly marked height scale.
The SHIFT screen system legs can be combined with all existing AV Stumpfl mobile screen systems. To adjust the screen height, one can start at the bottom of the scale and simply move the screen up to one‘s preferred position.
The SHIFT leg will lock automatically. To move the frame further down, one can just use the locking mechanism for releasing the frame. It is now possible to assemble a complete mobile projection screen system and then to adjust its‘ height in a matter of minutes.
Save time AND save money with premium quality components made in Austria.
