CenterFire Insulation Knife Kit

Item# CK50-1110

The CenterFire Insulation Knife Kit is a superior and easy to handle insulation knife. Installers can save time with smooth, easy cuts through foam and fiber, including tough-to-cut denim, mineral wool and polyester insulation. The non-serrated edge eliminates dust and debris – best tool available for cutting plasma rope. And the super sharp, slightly flexible blade requires fewer strokes to cut through insulation, leading to faster installations. The re-sharpenable carbon steel blade lasts far longer than conventional razor blades because they are crafted from high-quality tooling steel. This Knife Kit includes the 7 inch Insulation Blade.

MSRP: $34.95
