Overview

The Irwin 1964720 is a clamp weighing 1.9 pounds, with listed dimensions of roughly 31.81 by 9.25 by 5 inches. That length points to a long reach clamp meant for wide panels or multiple pieces rather than a small trim clamp.

Irwin's clamp lines mix quick release bar clamps with heavier duty models, and this listing does not specify jaw opening, throat depth or clamping pressure, only overall size and weight. The nearly 32 inch figure most likely describes the clamp's length or its packaged box rather than a confirmed jaw capacity, so treat it as a rough size guide rather than an exact spec.

  • 1.9 pound weight
  • Approximately 31.81 inch listed length
  • 9.25 inch listed width
  • Irwin branded clamp

Who it's for

Works for someone who needs a clamp with real reach across a wide workpiece or panel glue up. Not the choice for detail work needing a small, light clamp that fits into tight spaces.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out
  • Long reach suited to wide panels
  • Light at 1.9 pounds for easy handling
  • Irwin build quality
What to check first
  • Jaw opening and clamping force not specified
  • Size listed may reflect packaging not the clamp alone

Performance notes

At 1.9 pounds the clamp stays light enough for one handed use across long stretches, which matters when clamping wide panels that need several clamps placed in sequence. The listing does not include clamping force or jaw opening, so pressure capacity is not confirmed here.
