Its exclusive attachment system by means of clamp vises enables the user to mortise doors that have already been hung without damaging the surface. Secure, reliable grip. Works horizontally also. UC16K includes a height bar, making possible identical recesses on several doors at the same height, with no need to readjust the lock mortising template holder.
