Featuring a quick-change design, you can slide a sign in and out in seconds as long as the sign is made of a rigid material measuring 3/16 inches thick or less. With the stay tabs, you can rest assured that your signs will stay securely in place. Eliminating the need for tape, Hook & Loop Fastener, or screws needed to attach the sign to the stand, your signs will endure less damage over time.Thanks to the 4 fill holes, only about 2.5 pounds of play sand in the frame will ensure that it will stand against the wind without blowing away or falling over.
