These kits eliminate the double frame issue found on a competitor’s marquee. The double frame issue causes shadows along all edges of the marquee, which obscures the graphics and blocks the light. The main cause, is the oversized frame, with the undersized brackets. The brackets do not cover the entire frame, which is why you end up with all of the shadows.
The fix consists of a correctly sized frame, and a replacement lower piece, which is correctly sized for the new frame. This virtually eliminates the shadows at all four edges of the marquee. It only takes a couple of minutes to install. It does require you to have one of those snap-together marquees, with the poster frame style rails. If you are in doubt if this will work for your marquee, contact me before ordering.
