Tightening Rockler's new Auto-Lock T-Track Hold Down Clamp is literally an open-and-shut case—just press down the lever to secure anything from veneer sheets to lumber up to 2-3/4'' thick! Once set, the clamping pressure is always the same regardless of workpiece size, and is adjusted only if needed with the set screw. The clamp pivots 360°, allowing you to clamp near the workpiece edge to minimize obstructions. A large knurled wheel locks the clamp securely to the T-track. The toggle foot is adjusted with the knurled aluminum knob for best placement—no wrenches required—while the clamping foot pivots on a ball joint so it can adapt to any angle and is rubber coated to prevent marring. Simply lift the lever to release.

  • Auto-adjust mechanism allows you to clamp various thicknesses without readjusting
  • Center of clamping foot extends from 1-1/2'' to 3-1/2'' from center of track
  • Max height capacity is 2-3/4''
  • Clamping force is adjustable from 5-250 lbs of pressure
  • Large locking wheel secures clamp to T-track
  • Clamps slide into any T-track that accepts 5/16'' T-bolts, including our T-Track Table (#46654, sold separately) and many of the CNC Shark tables
  • Heavy-duty metal construction

Woodworking Experience:
Good clamps
These are great clamps for quick changeovers on the cnc.

I’ve notice that the adjustment screw either moves even after putting jam nut down, or the spring which acts as the self raising wears out..?
One actually broke on me, but I brought it to a store and was replaced with no questions.
So the longevity I think has variables, these are just what I’ve come across. But all in all I think these are good, especially with time of jobs.

I cut 4" holes and 2 of these hold everything down tight. Saves a lot of time compared to the vise clamps used previously. Fit the Jet drill press table tracks without problem.

Woodworking Experience:
Great idea!
It took a little fiddling, but once I figured out all the adjustments they work great! Not have to make an adjustments for different thicknesses of materials is a nice touch. Plus they basically duplicate some of uses of the Kreg clamps, without having to get Kreg clamps. Saving me money already!

Good value compared to Kreg
I wasn't sure what to expect to be honest, but I was pleasantly surprised with these clamps. Plenty of clamping pressure and great adjustability. The knob that's used for fixing them in place on the T-track was better than I expected as well. I was concerned with it being plastic, but it's holding up well. It's easy and quick to tighten down, and also easy and quick to loosen so that you can slide the clamp in the track. Just make sure your track is screwed into something solid underneath. These put a lot of strain on the T-track when clamping with force, but I have my track fixed securely and boy do I love these guys. I reach for them almost daily.

I use these on jigs, mounted in t slots, to clamp pices in place while I rout dados. They work well; the self adjusting feature saves a lot of time.

This is the handiest clamp to secure project to my work bench where I have T-Track system. Great tool!
Robert W on Dec 22, 2016
Thought they would work to hold face frames down while joining them with pocket screws. But they dont work worth a darn.
They are relegated to the "maybe I will find a use for them" drawer.
You cant adjust enough tension on the clamps to make them work !!

Zachary P on Oct 24, 2018
I purchased 2 of these, one clamps down nice and tight and the other does not hold the work piece tight at all. I can not figure out how to adjust it to clamp tighter. Can anyone help me?
Jayson M on May 12, 2015
BEST ANSWER: There is a phillips screw near the hinge in the clamp handle. Screwing it one way increases the clamping pressure while screwing it the other way decreases clamping pressure. This is the same system that Bessey Clamps uses for their auto adjust toggle clamps. They are a great system but the Rockler has the ability to easily adjust the angle from the t-track. Bessey is adjustable but not as easily as the Rockler. I absolutely recommend this clamp to anyone with a t-track table.
Country of origin?
A shopper on Apr 14, 2015
BEST ANSWER: This clamp is made in China.
Can I order from the UK?
Graham H on Apr 7, 2015
BEST ANSWER: Yes, you can order from the UK. When you check out you will get shipping options for UK addresses.
I really like this clamp. I would, however, like to have some with a longer reach than what is presently offered. Is that in the works?
Ronald C on Aug 29, 2017
Can the slot bolts be changed to 1/4" slot bolts?
A shopper on Aug 23, 2015
BEST ANSWER: I designed a wheel to accommodate a 1/4" nut based on the original wheel (using Sketchup). I then printed the wheel using my 3D printer. If you don't have a printer there are 3D services that could print it for you. Once adapted to accept 1/4" bolts, the clamps versatility grew at an exponential rate as 1/4" is a "standard" jig/fixture hardware.
Recently purchased two of these one is missing the clamping pressure adjusting screw and lock nut. Can you send me that part? Steve Denahan
Steve D on Aug 10, 2015
BEST ANSWER: Contact Rockler and they can get those sent out to you
Can the clamping foot be turned 90 degrees to use as a pressroll for resawing on a bandsaw? Also does the clamp fit in the miter slot of a bandsaw?
Mark H on Apr 29, 2015
BEST ANSWER: Replace the T-bolt with a countersink headed 5/16 bolt inserted into a split hardwood mitre track with a countersink hole. Tightening the wheel should spread the mitre track and lock it into the slot.
It says it comes with a 5/16" T-bolt, but the T-bolt I received is 1/2" x 13/16"; so it doesn't fit in any standard T-track. Am I missing something?
James B on Nov 25, 2018
BEST ANSWER: I see now. The bolt is 5/16", not the T-track that it fits into.

So it happens to not fit the T-track on two of my rip fences, but that's probably because they're not standard sizes. One is from Shopsmith and the other is from Incra. But I'm sure it will fit the Rockler track I have on order.

Thanks for the help.
