A whole new design for 2019!
Field-tested improvements include:
  • Updated design – lighter and more portable
  • Stronger and more durable for longer life in the field
  • Ergonomic – intuitive trigger release and blade guiding edges
  • Snap together legs – no-tools-required assembly takes less than a minute!
  • Less contact with the insulation – the Shut-N-Cut holds your insulation, not you
  • Contractor-grade Batt cutting – faster installation with straighter and safer cuts
The CenterFire Shut-n-Cut insulation cutting system is designed for quick and easy cuts through batt insulation including acoustic panels, denim (ultratouch insulation), polyester, mineral fiber (such as Rockwool), and polyethylene. Firmly holds any type of batt insulation preventing it from shifting. Get straight, accurate cuts. Compress foam, denim, fiberglass, mineral fiber, or wool insulation by 80% for up to 10x faster cuts. Extend the life of your knife blade through its Aerial Suspension Cut Guide System. The only surface your blade comes into contact with is the insulation – no wood to dull your blade. Reduce waste and save labor with faster insulation cuts and better accuracy. Long-lasting tool steel blades mean fewer blade changes. Completely Made in the USA. 1 year BulletProof Warranty.
