Overview

This is a 4.5 inch clamp from the brand Bench, weighing 13.3 pounds with a footprint of 9 by 4.5 by 8.6 inches. That weight is substantial for a clamp of this jaw size, pointing to a heavy, stationary design rather than a portable one.

The combination of a compact jaw opening and a double-digit weight suggests this clamp is built to sit firmly at a bench rather than travel to a job site. No material or mechanism detail is given, so exact clamping force is unknown.

  • 4.5 inch clamp
  • Weighs 13.3 pounds
  • Measures 9 x 4.5 x 8.6 inches
  • Rated 4.4 stars across 283 reviews

Who it's for

Works for a home or hobby workshop where the clamp stays mounted at a single bench station. Not the choice for anyone who needs to carry clamps between job sites, since the weight works against portability.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out
  • Heavy build suggests stability during use
  • Compact footprint at 9 x 4.5 x 8.6 inches
What to check first
  • Too heavy for portable or job site use
  • No clamping force or material spec given

Performance notes

At 13.3 pounds for a 4.5 inch clamp, the weight-to-size ratio is high, which typically means a solid cast body that resists tipping or racking under load. The listing does not give clamping pressure or jaw material, so strength claims cannot be made beyond that.
