Pony Jorgensen light-duty vice is for home and shop use. It is designed to mount to the face of wood work benches. The top edges of the jaws are typically brought flush with the bench top. It will mount to the face of any wood work bench but some work benches may need to be modified by mortising out part of the bench face or adding wood shims to allow jaws to be flush with the bench top. The jaws have drilled holes for attachment of wood facings which allows you to protect your work. The vise operates smoothly with Acme thread main screw and twin guide bars of plated steel. Castings are grey iron with orange baked enamel finish. It has a 165 mm jaw width and 115 mm maximum opening capacity. Weight capacity: 11.5 kg.
