The main use of the Express Shrink Wrapping tripod Cat. No. 42643 is to separate heat - shrink film from the boat it is covering. Combined with strapping, buckles and a tensioning tool, it provides simple and effective protection. This spacer enables air circulation and protects the surfaces of painted hulls or machines. Air circulation is extremely important, particularly on painted hulls where, in these applications, heat - shrunk film can enter into contact and cause blistering, which could lead to damage during storage or transport.
