Trim kits can add an extra element to your projection screen that will give it a more theatrical look and feel. The trim kit will also absorb any over spilling light produced by your projector. Our Trim kits come in two different fabrics, a 21 oz. flame retardant velour, and a 13 oz ploy-blend, inherently flame retardant (IFR) fabric. Standard color is black, but all materials are available in other colors.
