Overview
The Irwin 59400CD is a lightweight clamp weighing 8 ounces and measuring about 9.63 by 5 by 1.19 inches. That slim, low-weight profile points to a light-duty clamp built for smaller holding jobs rather than heavy stock.
At 8 ounces and just over an inch thick, this sits closer to a small spring or bar clamp than anything meant for cabinet-grade glue-ups. It has held a 4.2 rating across 3,641 ratings, respectable for a tool this size and price point.
- 8 ounce weight
- About 9.63 x 5 x 1.19 inches
- Irwin branded
- Slim, low-profile build
Who it's for
Hobby projects, small repairs, and holding light workpieces steady while you drill or glue. Not a match for larger woodworking clamps where high force across wide stock is the requirement.
Strengths and trade-offs
Drawn from this product's published specifications.
- Light at 8 ounces
- Slim profile fits tight spaces
- Irwin brand tool
- Likely limited force for larger stock
- No jaw opening or grip material listed
Performance notes
The 1.19 inch depth lets it sit flat and reach into tight areas where a bulkier clamp would not fit, and at 8 ounces it is easy to position one-handed. That same light build generally trades off against maximum clamping force compared to heavier bar clamps.
