Da-Lite Straight Screen Joining Clamp Series

Two screens hung end to end only stay in line if something holds them there. The Straight Screen Joining Clamp is the flat plane version of that fitting: it clamps adjoining cases together so the two surfaces sit level and stay level after the fabric has been raised and lowered a few hundred times.

Use the hinged clamp instead where the run has to turn a corner. Both are Da-Lite screen accessories ordered per joint, and this one is listed as an active stock part.
