The Profi 14 vice lacer is a high quality hardened steel tool. It's designed to suit high volumes of belt lacing carriest out by dealers. A splice width up to 210mm (19 fastener segments) can be installed in one step. Splice isntallation is performed with the hand punch and hammer or with the optional air hammer and punch, but requires a vice to hold the tool in place. Wider belts are spliced by progressive step by step installation.
