Product Description

These light-duty Jorgensen® Bar Clamps are the standard in home and professional workshops. These clamps have a load capacity of 600 lbs. Jorgensen® Bar Clamps are quick to tighten and release and are even suitable for tight spots. Lightweight steel bar is rated at 10,000 p.s.i. and is rust resistant.

From the Manufacturer

Perfect for fixtures or small boxes, the 12-inch steel bar clamp has a 2-1/2-inch reach and a sliding head design. The sliding head is threaded to accommodate the screw. All adjustments are made in the movable sliding head, making this style easy to open and close and suitable for close-quarters clamping. A multiple-disc clutch permits instant adjustment, secure hold, and easy release. The strong yet lightweight bars are rust-resistant. Constructed of 1/4-by-3/4-inch plated steel with a 3/8-inch-diameter steel screw. 600-pound clamping pressure.

Customer Reviews

The best, can't go wrong.
Timothy R. Bartlow
I also use these clamps in construction jobs (where those protective pads aren't really needed), and they have worked well.
Victor H. Agresti
Enough pressure can be applied for glued joints without excessive flexing.

No woodshop is complete without several good bar clamps. Thatis what Jorgensen has here. I have several from 12" to30"(+) and use them all the time. I do prefer bar to pipe clamps, but that may not be the popular opinion. You can practically squeeze a glue joint dry with these clamps so why would one want to use heavier, pipe clamps? Jorgensen makes a high quality product here. Go for it.

I have four of these clamps and I need about eight more. When it comes to achieving a strong solid glue joint, good clamping is absolutely essential. These clamps are easy to use with the sliding clamp head and can apply a strong pressure to the piece you're gluing. You can put a wood shim under the jaws to avoid marring the wood surface. The bar will rust if not oiled or waxed but a little steel wool will clean it up. The 36" will handle most clamping needs and the price is low enough to allow buying enough for uniform clamping.

You can't beat these clamps for the money. Enough pressure can be applied for glued joints without excessive flexing. Also, you can accumulate a good collection without going broke.

Of course, you get what you pay for, but the Bessey version of this clamp (at about $3 more) has a much larger bar and can apply a great deal more pressure. The bar on this clamp bends considerably, but if you are doing primarily light clamping it should not be a problem. I've used this clamp (among others) for several years without permanently bending the bar.

If these clamps are used as their design is intended (gluing up cabinet, drawer, etc joints), they perform adequately. The thumbscrew works just fine for applying the desired pressure. The adjustable head moves freely and effortlessly IF the bar is clean. Be sure to immediately remove any glue drippings that finds its way to the bar or the next time you go to move the head it will hang up. I used these clamps in gluing up a 2x4 laminated workbench top. This operation stretched them (and then some) to the maximum of their capability. Multiple clamps spaced closely together were required to press the bow out of some of my pieces. In retrospect, a heavier duty ¾" Pony clamp would have been better fitted for this particular job. But if you use these within their limits, they will perform for a long time.

I just bought a pair of these (why does Amazon ship them each in their own huge box?), but already have a pair of these clamps in the 12" size that I have used extensively over the last 15 years or so and would not be without. Sure, they're great for clamping wood for gluing (I 'pad' with wood scraps), but they're also wonderful for larger jobs like building fences and decks, where you don't have a helper but need the board held or sitting in a certain place vertically (you don't have to actually clamp -- just clamp to a post and set the board on top of the handle side of the clamp until you can level and screw -- do you know what I mean?).

Anyway, I have a Heavy Duty version of the Jorgensen bar clamp and it would make a great weapon for pounding on an intruder, but it doesn't seem to have any better clamping ability than the 3700 series -- doesn't get any tighter to pull warped deck boards into place for example. In fact, I dislike the rubber pad thing, which is why I don't buy Bessey clamps, although many people like them.

Oh, I went to the local Chinese tool store at the flea market and bought several cheap bar clamps in various sizes. Never again! Tighten them just a bit too much and they make a 'tink' sound and are worthless from then on.

For the money you just can't beat the Jorgensen 3700 series clamps.

I am a fan of this saying that I made up : "A woodworker can never have too many clamps!" - which actually prompted my daughter once to buy me a C clamp for my birthday ! :-) I'll bet I'm not all that original - a clamp is a woodworker's essential tool.

I had a project where I needed a bunch of larger clamps; I was looking for 3 and 4 foot openings.
I actually want to buy the ratcheting style of clamp, but they cost more and I needed several so the cost would add up.

In actual use, these worked very well and in some cases I was able to apply more pressure than what I probably would have gotten from the ratcheting models. I can also adjust these much faster than the ratcheting models.
I have both types from long ago; this type ages better.
The ratcheting style sometimes slips and needs maintenance (cleaning, lubrication). My Jorgensen's from years ago - no fuss.

My only complaints: the protective pads fall off very easily.
At some point I just started to use shims.
However even when they fell off and I didn't realize, the surface (oak plywood) did not get marred.
The other complaint is just obvious from the design: the points of pressure are smaller so on some occasions I needed to put a block between the jaws and the material to transmit the pressure over a longer area (for trim and also sometimes my dados were a bit tight)

Of this type of clamp, I am not familiar with other brands that make this style, but since I've had (and still have - 20++ years?) Jorgensen clamps in the past and work the way a tool should work without melodrama, I stuck with this brand.
