Attach a CenterFire SuperShear Blade to your corded or cordless SuperShear to trim spray foam insulation quickly and easily. Choose between an Open Cell or Closed Cell Blade to suit your needs. The Open Cell Blade passes through open cell foam insulation without causing cling. It can also be reversed when one edge begins to dull for a new, sharp cutting edge in an instant, and it can trim walls up to 10 ft. high without a scaffold. The Closed Cell Blade option aggressively cuts through closed cell insulation in one smooth cut; you can also trim walls up to 9 ft. high without a scaffold. Both blades are lightweight and offset from the handle, making it more comfortable to use while producing cleaner cuts. These SuperShear Blades are Made in the USA with Global Materials.
