Rockler Auto-Lock T-Track Hold Down Clamp

Automatically adjusts for thicknesses from 0'' to 2-3/4''—securing your work is as fast and easy as flipping a switch!
Item #
78% of 100

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

Best clamps for use on jigs and fixtures
I have used these clamps on my table saw sled, drill press table and on custom fixtures I've made for my bandsaw. Being able to set the pressure and have the clamp work on all different thicknesses of stock is a real plus. I've seen reviews here where people have said they couldn't get enough pressure with the clamp. That has NOT been my experience. They're not adjusting the pressure screw correctly. These clamps are great!

Robert H on Mar 31, 2020
This has a long low profile reach. But its not for holding thick heavy objects. I've broken them when trying to clamp a machinist vise to a drill press - didn't work out well for the clamp or my wallet.

Ramon G on Apr 26, 2020
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
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.
Is the extended reach large toggle clamp foot compatable with this?
Benjamin H on Oct 21, 2018
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.
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
Will this fit in a standard 1/4 t track?
Roger on Dec 24, 2019
BEST ANSWER: This clamp slides into any T-track that accepts 5/16'' T-bolts.
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.
is this clamp made in the USA?
Don S on Apr 19, 2020
BEST ANSWER: Per inscription on package: Made in China.
what is the maximum thickness board that this can clamp down?
JAY F on Jan 2, 2020
BEST ANSWER: I don't know (because I haven't done the trials to determine exactly). But my ^guess* is perhaps two inches or a bit greater, but probably not three inches. I'm pretty certain that I could clamp the 1 1/2" side of a "2 X 4," but certainly not the 3 1/2" side. Most of my experience, however, is just clamping 3/4" stock.
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.
What size T-track is required for Auto-lock T-track clamp??
Dennis on Oct 1, 2016
BEST ANSWER: 3/8" slot and 1/2" wide inside the track for the bolt head
I have a 3/4" by 1" T-track on my Laguna band saw. Will the T bolt for this clamp work for this configuration?
William D on Mar 25, 2020
BEST ANSWER: I have not seen a T-Track on a Laguna band saw. Has it been modified? There is a 3/4" wide miter slot on the table, but this clamp will not work in it.
