Shur-loc® panels are the basic component to our system. Plastic connectors are affixed to a precision cut piece of fabric. The designs and shapes are representative of a fabric at its maximum tension. You simply snap in a new Shur-loc® mesh panel and tension using your "E-Z" Stretcher. It's that simple! Not all mesh colors are available in all mesh counts. White mesh is stocked in mesh counts from 17 to 195. Yellow mesh is not available in 17, 25, 40 or 60 meshes.
