This is a hard working, heavy duty, all purpose sign frame. This classic A frame sign can display two 24" x 36" coroplast graphics, one on the front and the other on the back. Graphics simply just slide into the frame with tabs on the left and right sides that hold your graphic in place. Each sign frame has four fill holes (two on each side of the frame) that allow you to add sand to give your Signicade extra weight for use outdoors. Simply remove plugs from fill holes and fill each holewith sand. Up to 2.5 lbs. of sand per hole for a total of 10 lbs of added weight. If you'd like to produced your own graphics these accept any rigid materials up to 3/16" thick.
