Welcome to Lowell Thomas Tool, Inc. - Home of the JackClamp
A Patented and 100% Made in America Grip-Style Bar Clamp
The JackClamp is the only bar clamp with a unique parallel bar design - enabling it to do so much more than other clamps.
Built to last, never lose clamping strength and be the fastest, most versatile tool you'll ever own.
The flexibility of the JackClamp is what makes it such a great tool - both bars can be completely removed and reassembled around or inside your project, allowing you to use it in places that other clamps just can't fit. The attachments included with every JackClamp System allow you to meet the challenge of even the most complex projects. Whether you're welding, installing cabinets, building a deck or just working at the shop, you're going to love using the JackClamp.
