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.

  • 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.

What stands out
  • Light at 8 ounces
  • Slim profile fits tight spaces
  • Irwin brand tool
What to check first
  • 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.
