<style type="text/css"><!--td {border: 1px solid #cccccc;}br {mso-data-placement:same-cell;}--></style> <p>For over 45 years, Dubuque Clamp Works has been crafting specialized clamps of all kinds in their Dubuque, Iowa factory. Renowned for their uncompromising quality, they have been an industry leader for decades producing some of the best and most useful clamps on the market, built to last for generations.</p> <p>These Universal Bar Clamps are crafted from extruded aircraft aluminum and injection molded aluminum alloys, making them lightweight yet extremely rigid. They are perfect for panel and casework glue-ups. The rigid extruded U-channel beams measure 1.37” x 0.850” with 0.110” thick sidewalls and have detents every 5/8” for quick adjustments. The aluminum beams do not react with wood glues, preventing staining. </p> <p>The fixed head is riveted to the beam, featuring ½” diameter smooth-turning acme threads and a large "wing" knob for easy one-handed operation, generating up to 1000 pounds of clamping pressure, more than enough to handle any job in your shop. Jaw travel is 1-1/2". The moveable head wraps completely around the beam, slides easily, and locks into any of the detents with an easy-to-adjust spring action lock. Both heads remain square to the beam under pressure. The clamping faces are 1-1/2” x 1-1/2”. These clamps can sit upright on their own during panel glue-ups. Available in 24”, 36”, 48”, 60”, and 72” lengths. The listed size is the maximum distance between the jaws, or largest piece that can be clamped. Overall length is 7" longer that listed size.  </p> <p data-mce-fragment="1"><img alt="Prop 65" src="https://cdn.shopify.com/s/files/1/0091/2169/3747/files/6pt.png?4150" title="6pt.png" data-mce-src="https://cdn.shopify.com/s/files/1/0091/2169/3747/files/6pt.png?4150"><strong>WARNING:</strong><span> Cancer and Reproductive Harm - </span><a href="http://www.p65warnings.ca.gov/" data-mce-href="http://www.p65warnings.ca.gov/">www.P65Warnings.ca.gov</a></p>
