Description
The Duratec DTB300 is a 300mm bar clamp for carpentry and woodworking assembly. Its one-handed mechanism helps you hold and position a workpiece while tightening the jaws. For tasks that need outward pressure, it also converts to a spreader without additional tools.
300mm bar clamp features
The clamp combines a hardened A3 steel bar with a PPGF30 body. This engineering plastic contains polypropylene and 30% glass fibre. Soft nylon jaw pads help protect the contact surfaces, while the quick-release catch makes locking and unlocking straightforward.
Use the spreader conversion catch to unlock, adjust and relock the jaw. In spreader mode, the working range extends from 160mm to 450mm. This provides a second function from the same woodworking tool.
