Overview
Weighing 3 pounds, the Irwin 1964749 clamp does not have a published jaw opening, clamping force or mechanism type on this listing. Irwin's reputation in shop clamps, backed by a 4.7 rating across nearly 6,900 ratings, is the main signal buyers have to go on.
At 3 pounds this sits in the range of a mid sized bar or trigger clamp rather than a light spring clamp or a heavy duty pipe clamp, though the exact style is not confirmed here. Irwin's clamp line is widely used in woodworking and general shop work, and the strong rating across nearly 7,000 ratings backs that reputation.

- 3 pound item weight
- 4.7 rating across 6,820 ratings
- About 200 units bought in the past month
Who it's for
Fits woodworkers and DIYers who need a mid weight clamp for general glue ups or holding work in place, and who trust Irwin's reputation given the listing lacks a jaw opening or clamping force spec. Not for anyone who needs a confirmed maximum opening width before buying.
Strengths and trade-offs
Drawn from this product's published specifications.
- Strong 4.7 rating across nearly 6,900 ratings
- 3 pound weight suits general shop clamping tasks
- No jaw opening width or clamping force listed
- Clamp mechanism (trigger, screw or bar) not specified
Performance notes
At 3 pounds this is heavier than a small spring clamp but lighter than a large pipe clamp, suggesting a general purpose bar or trigger style clamp for typical shop clamping tasks. No jaw opening or clamping force is listed, so matching it to a specific job width is not possible from this data.
