The QuickStall Frame features a self-finishing casing that is intrinsic to the frame. The casing covers the immediate wall surface ½inch all the way around the roughed in aperture. The frame system will support images up to 10feet in width and features a 3inch reveal all the way around the image area. The QuickStall Frame has a 2 ½inch sill depth and measures 2 ¾inches in total, front to back — including the self-finishing casing detail. This frame system finishes beautifully.
