Good for small glue-ups and hobby joints where a larger clamp will not fit; the short reach means it cannot replace a standard bar clamp for furniture-scale assembly.

Overview
This is a four-pack of one-handed mini bar clamps built for small workpieces and confined spaces. Squeezing the trigger draws the resin body along the bar to apply pressure, and a second trigger releases the jaw right away. Non-marring pads at the jaw protect the material being clamped.
The main draw is scale: these clamps run about a quarter smaller than IRWIN's standard Quick-Grip line, so they reach into tight assemblies and small parts a full-size clamp cannot fit. That compact frame is also the tradeoff, favoring precise small-part work over long reach or heavy spanning jobs.
Who it's for
Fits hobbyists, modelers, and light woodworkers who need an extra hand on jigs, small joints, or repairs in tight corners. Also useful as a backup set alongside full-size clamps for a shop's smaller jobs. Not a fit for cabinet-scale glue-ups or any job needing sustained heavy pressure across a wide span.
Pros and cons
- One-handed trigger for quick clamp and release
- 150 lbs of clamping force in a small frame
- Jaw pads guard against scratches and marring
- Steel bar and resin body resist flexing
- Clamp opening capacity not listed on the packaging
- No swivel or angled pad feature mentioned
- Only available in one color, blue
- Short bar length limits use on larger workpieces
Performance notes
Clamping force comes from the pistol-grip trigger acting on the steel bar; squeezing repeatedly ratchets the jaw tighter, and pulling the release trigger drops it in one motion. The bar is high-carbon steel, chosen for durability in everyday hand use rather than high-precision tolerance work. Reinforced resin in the body and jaws resists flexing under load, which keeps the rated force consistent across the squeeze range.

Frequently asked questions
What size workpieces does the IRWIN Quick-Grip 1964758 mini bar clamp fit?
It's sized for small parts and tight spaces; the 6 inch bar is shorter than IRWIN's standard Quick-Grip clamps, so it is not meant for full-size panels or furniture assembly.
How much clamping force does this clamp apply?
IRWIN rates it at up to 150 lbs of pressure, applied through the pistol-grip trigger onto the resin body and steel bar.
How many clamps come in the pack?
The set includes four 6 inch one-handed mini bar clamps in blue.
Can the clamp be released with one hand?
Yes, a trigger on the handle releases the jaw right away, so the other hand can stay on the workpiece.
Will this clamp mark or scratch my workpiece?
No, each jaw has a non-marring pad meant to grip without scuffing the surface.
