Overview
The Irwin 1964758 is a clamp weighing 454 grams, about 1 lb, with a listed size of 21 x 8 x 2.5 inches. That box like footprint likely reflects packaging rather than the clamp's actual reach, which isn't separately confirmed.
At roughly 1 lb this reads as a light, single-hand clamp rather than a heavy shop clamp, though jaw opening and clamping force aren't specified. Irwin's bar clamp lines commonly fall in this weight class, but that isn't confirmed by the spec sheet alone.
- 454 gram weight
- 21 x 8 x 2.5 inch listed size
- Irwin model 1964758
- 4.7 rating
Who it's for
Suits light duty clamping for woodworking or DIY repairs where one-handed operation matters. Not for shop work needing a confirmed high clamping force, since that figure isn't listed.
Strengths and trade-offs
Drawn from this product's published specifications.
- Light weight for one-handed handling
- 4.7 rating across 23,290 ratings
- Recognized Irwin clamp line
- Listed dimensions appear to be packaging size, not clamp reach
- No jaw opening or clamping force spec given
Performance notes
At about 1 lb, this sits well below heavy duty bar or F-clamps, pointing to light duty, one-handed use. The 21 x 8 x 2.5 inch figure reads as a shipping size rather than clamp reach, so actual working length isn't confirmed.
