Quick-Grip® SL300 Clamps

Since not every workpiece has perfectly even edges, the Quick-Grip SL300 adds a swivel jaw that conforms to angled surfaces and combats the inevitable flexing that occurs with resin clamps. It also features a quick-release push button that makes it easy to convert the clamp to a high-performance spreader. A heavy-duty I-Beam Bar allows you to apply up to 300 lbs. of clamping pressure with minimal bending and flexing. All these improvements come without any added weight, so the clamp retains its chief benefit: simple one-handed operation.

  • Quick-Release™ trigger provides fast positioning and maximum hand comfort
  • High-tech resin construction for light weight and durability
  • Heat-treated, black oxide carbon steel I-Beam Bar for extreme rigidity
  • No-mar resin jaw pads are removable
  • Swiveling jaw for angled workpieces

Woodworking Experience:
Nice Clamps
I've had these clamps in different sizes for years. Great clamps. The only complaint is sometimes the nut falls off that keeps the fixed piece on.

I like these kind of clamps because it's easy to hold a project and clamp it at the same time without any additional help.

Quick indeed
The one-handed operation of these clamps make them my “go-to” clamp when I need a “third hand during project assembly. I will buy a few every time they go on sale!

I really like these clamps!
My motto is you can never have to many clamps. I make cabinets and these are very easy and quick to use. Every size of these clamps are in my shop and used at some point in every project. Easy to install and adjust them one handed.
Never a problem, I always have them in easy reach.

DOUG G on Jul 30, 2018
Why can't I get the quick release button to release so I can convert the clamp to spreader as advertised. The button says 'push' but the end does not release. Is there a secret?
george b on Feb 8, 2017
BEST ANSWER: It’s actually a sliding mechanism, not a push button to release the jaw.
my end piece of the clamp broke do you have replacements?
phil b on Aug 18, 2017
where can I get replacement pads?
Al W on Oct 25, 2017
What are the dimensions of the shaft?
konner b on Jul 18, 2018
BEST ANSWER: Shaft measures 11/16" x 3/16" x listed length for the heavy duty clamp.
Can you post the throat depth and clamping width for each clamp? Is the listed length the length of the bar, or the maximum distance between the pads? This should really be provided by Irwin or Rockler rather than a question. This would be key information to know before buying any clamp. Length doesn't really tell you much if you don't specify length of what.
Bill H on Dec 20, 2015
BEST ANSWER: The specified clamp size (e.g. 6", 12", 18", etc.) is the distance between pads at the largest possible opening. The throat depth, from the top of the metal bar to the center-line of the pivot point of the stationary pad, for all three of the mentioned clamp sizes, is approximately 2-1/4"
