Overview
The IRWIN 275 is a bar-style clamp measuring roughly 24.6 inches long, weighing 1.52 kilograms (about 3.3 pounds). Irwin is an established name in clamps and hand tools, and this model's length places it in the range used for wide panels, doors and long glue-ups.
At just over two feet in length, this clamp is built for jobs a small quick-clamp cannot reach across, like door frames, wide shelving or multi-board panel glue-ups. Irwin's clamp lineup spans several bar lengths, and the 24.6 inch dimension here is the main clue to where the 275 fits in that range. No further spec detail, such as clamping force or jaw material, is listed.

Who it's for
Suited to woodworkers and DIYers who need reach across wide stock rather than tight, small-scale clamping. Anyone whose projects stay under about a foot wide will find shorter clamps easier to handle.
Strengths and trade-offs
Drawn from this product's published specifications.
- Long 24.6 inch bar reaches across wide panels
- Reasonably light at 1.52 kilograms for its length
- Irwin is a long-standing clamp brand
- No clamping force or jaw material specified
- Long bar adds bulk for small clamping jobs
Performance notes
The 24.6 inch length is the dimension that matters most here, since it determines maximum opening capacity for the job at hand. At 1.52 kilograms, it is light enough to hold and reposition one-handed during a glue-up, which is typical of bar clamps in this size class.
