Q: Should I use a standard top masking or an extra drop masking border?

It depends on how high you want to hang the screen. If you are planning on a high ceiling or in-ceiling installation, use a product with an extra black masking border like E24 (24″ drop) or E30 (30″ drop) model. Aside from that, our general product lines will accommodate your typical home or commercial presentation room ceiling heights.  All of our manual and electric screens are suitable for wall or ceiling installations.
