Surely you don’t want your project to get delayed just because you couldn’t place the surface properly. That’s why you are looking for the best parallel clamps. But finding the perfect match won’t be that easy.

Parallel clamps are made for heavy-duty use and have a unique mechanism. As these clamps are used for various purposes, they are designed differently. Those clamps which are meant to handle regular-sized workpieces, may not be good for heavy loads or giant workpieces.

If you pick up a parallel clamp which is good but not suitable for your work, surely you won’t be able to get the best performance. It means you have to precisely define your need and then select the tools.


Just sit back and relax! We offer you the one-stop solution in lieu of brainstorming while surfing several websites.

Parallel Clamp buying guide

To pick the best one is not everyone’s piece of cake. Though it requires much research, you don’t really have to do it. We are here to provide you a comprehensive buying guide.

A few things are to consider to get the best parallel clamps. Let’s discuss them point by point.

Parallel bars

To keep your workpiece secure, you need perfectly parallel bars. Your workpiece is placed between them. So it means you need to pay much attention to this point. Make sure that the bars are perfectly parallel. Sometimes the bar bends due to shipping or packing problems. If this happens do knock the door of the seller. Never compromise in this very crucial point.

Jaw Design

The jaw is another important element of the set. The jaw holds your workpiece and ensures safety. The jaw must be strong enough to apply pressure and to hold objects. Besides, flexible and soft enough for the ease of your work and to protect the object from getting damaged. So, do check the jaw very carefully. It should not be bend or damaged.


Sometimes you need to spread your project rather than squeeze it. Then the spreader comes into play. Make sure that the bar clamps you are buying have a spreader option. This will help you by giving extra service.


You need strong parallel clamps for support. Strong material increases durability. Aluminum is the best option for durable and heavy use. But it makes the clamps expensive. Plastic materials are not for heavy use. Then what remains? Yes! “Steel”. Always prefer steel components over the plastic to ensure that the clamps can hold a heavy load. Do prefer soft grip for comfort and easy operation.

Maximum Clamping Force

Do check how much clamping force the jaws can hold. Sometimes you need massive clamping force. If the jaws are not meant for dealing with that force, they will gradually bend. So, the maximum clamping force is surely an important point.
It is expected of a parallel clamp to have a clamping force greater than 1000 lbs. Anything below that might prove to be troublesome.


Try to be sure that the product has soft rubbery pads beneath the foot. These pads ensure slip-proof clamping and stable the whole project.


The handle should be free enough to move for a fast clamping experience. Soft grip on the handle is always preferable for comfort.

3. IRWIN Tools Parallel Jaw Box Clamp

48 inches

Why pick this?

You’ll have a comfortable time using this clamp especially due to the ProTouch ergonomic grip. It’ll reduce a lot of stress and strain on your hands. And then there’s the trustworthy locking mechanism, it quite securely holds the workpieces in place.

Having a 3¾ inches jaw depth this clamp has a substantial pressure distribution. Speaking of jaws, the clamp’s jaws can be extended to an astounding 48 inches. This makes all the difference and adds a heck of a lot of versatility.

You’ll have no issues doing corner joints due to the machine precision 90-degree angle on the clamp. Though corner clamps also a nice option to make a corner joint. Another rationality for that is the bewildering 1150 lbs of clamping pressure. The clamping pressure alone says how much of heavy-duty clamps that this is going to be.

Apparently, the clamp having a Resin body prevents glue adhesion. I need not say how handy those features gonna be. Having your glue stuck to the clamp is a gruesome experience.


It’s a fantabulous feature that the clamp comes with a resin body, but that doesn’t make a difference if it doesn’t last all that long. So, after a while, this clamp might just turn out to be like one of those regular everyday clamp having glue stuck to it. This way the metal of the clamp degrades overtime.
