Hot Knife

For the best results during sleeving installation, the sleeving should be cut with a hot knife. The heated blade slices through most grades of sleeving and seals the ends to prevent fraying during installation.

We offer an assortment of tools to accomplish this, ranging from heavy duty, high volume devices to portable gas powered units.
