Key Features
Overview
The Klein Speed-Klamp Quick Clamps, 12-in., 150-lb., 2-Pack (47551) are quick-release bar clamps designed for holding material in place during woodworking and metalworking. Each clamp opens to 12 in. (305 mm) and applies 150 lb (68 kg) of clamping force.
The pads pivot and detach, so they adjust to different surfaces and hold securely. Extra-long pads spread the pressure out evenly, which reduces the chance of marring the material. An extra pad head is included in the design for round or irregular surfaces.
Move the base arm and the clamp converts into a spreader. The set is light-duty construction with a steel bar and rubber jaw pads, and each clamp measures 19 in. (483 mm) overall.
This two-pack suits woodworkers, metalworkers and general contractors who want fast, one-handed clamps with extra reach.
Grip Without Marring

Long rubber pads spread the load so finished surfaces stay clean.
- Pivoting, detachable pad heads
- 2-1/4 in. (57 mm) jaw pad height
- Converts from clamp to spreader
