The 120V 24862B Tensioned Advantage Deluxe Electrol 87 x 139" Ceiling-Recessed Motorized Screen (fabric, roller, and motor available separately) from Da-Lite is designed to eliminate the extra step of finishing the screen with trim. The Advantage line of projection screens is designed with ceiling trim already in place. Once the screen is installed, the screen's trim conceals the rough opening in the ceiling, eliminating the need to complete additional trim work. Sliding installation brackets make it easy to attach the screen housing to the structure above the drop ceiling.

Tensioned screens ensure the smoothest surface possible, and the screen features a closure door that hides the open space and screen in the ceiling, providing a cleaner aesthetic. The screen features simple in-ceiling installation that can be done in two stages. The screen case can be installed during the rough-in construction stage, and the fabric assembly can be completed during the finishing stage.

Note: This box is part of a system. To complete the system you will also require the fabric, roller, and motor assembly. Purchasing the box first allows the box to be installed during the "rough-in" phase of construction. The screen and other components can then be installed once construction is complete. Please be sure to select the fabric, roller, and motor assembly with the exact size and features as designated by this box. The fabric, roller, and motor that goes with this model number is: 24862F.

Q: 1. Can I use this with Sigma S 150-600mm ?

A: No problem. I mount a Nikon D750 with the Sigma 150-600 and it is very stable. The ballhead spec is 37 lbs load, and it is very solid. Tighten the screw and it doesn't sag at all. You may want to adjust the QR on the lens foot to get the best balance.

Q: 2. Does this mount work with a drop ceiling?

A: This mount will not connect directly to a drop ceiling. It could pass through the ceiling tile to the architectural ceiling above.
