Universal Bar Clamps – Lightweight Strength, Built for Precision

Designed for woodworkers that value American Made quality, Dubuque Clamp Works Universal Bar Clamps combine lightweight construction with unmatched clamping power. Crafted from extruded aircraft-grade aluminum and injection-molded aluminum alloys, these clamps offer exceptional rigidity without added weight—just 2 lbs for a 24" clamp. Despite their light feel, they can handle up to 1,000 lbs of pressure without flexing, making them ideal for panel and casework glue-ups.

The extruded U-channel beam measures 1.37" x 0.850" with durable 0.110"-thick sidewalls and features detents every 5/8" for quick, precise adjustments. The non-stick aluminum surface won’t rust or react with wood glue, helping prevent staining and cleanup hassles.

The fixed head is securely riveted to the beam and equipped with a smooth-turning 1/2" precision-ground acme thread and a large wing-style knob—easy to operate one-handed, even with a single finger. The movable head slides effortlessly and locks into place using a spring-loaded detent system, staying perfectly square under pressure. Both heads deliver a consistent 1-1/2" jaw travel, with 1-1/2" x 1-1/2" clamping faces for secure, even pressure.

These clamps also stand upright on their own—making panel glue-ups faster and more efficient.
