Da-Lite Fast FoldHas redesigned the fast fold screen frame, the New Fast-Fold NXT is a custom lightweight aluminum extrusion, easy to assemble, has  increased strength and solid corners, finally no more bent frames.  Also, the screen has been redesigned, with a new 4K ready surface and new vinyl binding.  No more snaps, the screen wraps the frame edge and clips into the side extrusion.  The leg has a new design too, no more speedy cranks, easily adjust the screen height while it is assembled with micro-sawtooth height adjustment and independently leveling feet for uneven floors.
