The biggest breakthrough in carpet seaming since hot melt tape!The #893 by Taylor Tools features a unique welding head that applies a precise amount of hot melt adhesive to the carpet seam edges, locking in the face yarns and permanently welding the carpet seam together. The rear edge guide allows close observations of the coating process and provides precise backing alignment.The result? A joint that is actually stronger than the rest of the carpet with a seam that will remain flat even after stretching!
