The Tin Knocker manual insulation cutter slits fiberglass insulation to length and width.

Material is fed into the machine with a crank handle. The desired width is immediately cut with the adjustable slitter blade while the insulation is fed into the blade. The embedded scale makes for fast and accurate cutting

Once the material is at the desired length the operator pulls the handle, quickly and efficiently slitting the insulation to length with the crosscut blade.

The result is a simple and easy way to make repeatable cuts to fiberglass insulation.
