SLAP BAND FOR ROLLERS
New and improved Slap Bands are silicone consisting of layered, flexible stainless steel bistable spring bands sealed within a silicon cover. The band can be straightened out, creating tension within the springy metal bands. The straightened band is then slapped against the rollers holding the fabric causing the bands to spring back into a curve that wraps around the roller securing the fabric to the rollers.
6 Bands in a pack.
