Last Updated on January16, 2021
You might be very attached to your woodworking job, but is your clamp attached to your project the same way?
If your answer is NO! Then we welcome you to this useful write-up. Here you will get all the answers to your “if I should need this tool” or “why should I need it”.
A solid best parallel clamp is a must-have because it promises to do its clamping job for longer than its expectation. And, that’s why we compiled 6 of the best parallel clamps.
The tools have not only been positively reviewed by their users but also been loved by them. So, without blabbering much, let’s start the review!
What is a Parallel Clamp?
Woodworkers wish for stable parallel jaw clamps similar to toddler years for a new toy car. These come with steel-reinforced and resin-covered jaws three to four inches in depth. They line up tightly parallel to each other with their beefy steel bars.
The heavy-duty handles and screws provide enough camping strength. They have gained a considerable reputation among hobbyists for high performances and prices.
Parallel clamps are an essential tool in a woodworking workshop. They have a very critical use as they hold and grip objects that would have difficulty grasping otherwise. These clamps do not slip away or break when they are fragile.
These clamps are intended to help you finish work a lot quicker and faster. These also perform the essential function of holding the objects in place to provide steady support. They are also used in welding because the heat does not destroy the clamps.
PARALLEL CLAMP VS. PIPE CLAMP
Pipe clamps are a low-cost and versatile option for gluing projects. However, they will move about if they are not placed correctly. Parallel clamps do not move so quickly and do not carry the same issue. They are a lot expensive too.
Besides being inexpensive, pipe clamps can be used for their wide range of clamping capacities. They can help you replace your pipe with a longer and shorter one. They can even help you extend it. When it comes to a parallel clamp, you cannot adjust the length.
Pipe clamps also work with cauls. They produce an even amount of pressure. One type of cauls extends the pipe clamp jaw while the curved is used to distribute the pressure of two clamps.
Pipe clamps also allow higher clamping pressure. A usual parallel clap reaches 370 pounds of pressure. The ¾” pipe clamp reaches 1,050 pounds, and the beam clamp can reach 1,350 pounds. You can also reverse the pipe clamp to expand the pipe tap for the first time.
SCREW CLAMP VS. PARALLEL JAW CLAMP
Screw clamps have been around for centuries. These consist of two opposite-facing screws that project into wooden jaws. These jaws will open and close with the way the screws are located. You can use handles to turn them quickly.
You can use these to clamp the surfaces that are not parallel. Since the clamp jaws are wood, they will not damage the wooden workpiece.
Parallel clamps are helpful for large glue-up jobs. They come in different sizes, which depends on the size of the wood you are working on. These bars are parallel to each other, as the name suggests, at the 90 degrees angle at the bar.
These clamps are used for square assemblies. Keep the bars perpendicular when you are making boxes using the parallel clamp. These can be done using an assembly square which is a right-angle clamping jig.
How To Use A Parallel Jaw Clamp?
- Spot the clamps, so they do not cross slide when you are framing the surface.
- Framing blocks are beneficial when you have to clamp objects like a picture frame or a box. You will need more than just two sides for clamping boards.
- Set the blocks as you need them.
- Set one of the clamps in the deep slots that go all the way around.
- Place the clamp flush on the table.
- Cross the clamps going on the other set and place the clamp flush on top of the thinning locks.
- You will have to apply pressure from both sides of the clamps.
- The square and clamps set are instantaneously set once you know where to place the components.
- A cross tick framing the blocks can be installed using the bench clamps.

Why are parallel clamps so expensive?
Parallel clamps are expensive because they are constructed out of metal. The manufacturers use top-quality material such as steel, iron, or other metals, to provide every woodworker with the toughest clamps possible. The woodworkers also use the clamps for a very long time, so they do not require frequent replacement. Therefore, supply and demand also affect the price.
Parallel clamps are not consumable. Once you purchase a reliable and strong parallel clamp, you would need to buy another unless you need a different kind of clamp. These clamps last a lifetime.
Parallel clamps may be expensive, but they are worth the price. They are helpful when you are attempting to good square fit-ups. Parallel clamps are also expensive due to the nature of the application. Some do not even ask the price unless it appears on their credit card receipt.
Their rational thoughts are they wanted it because it is a necessity to their work. The nature of demand does not help. Woodworkers will continue to purchase the clamp as it is a one-time investment that will provide significant assistance to their projects.
Buying Guide :
Parallel clamps are essential woodworking tools for professional woodworkers. A smart parallel clamp purchase will be a good investment for wood crafters other than the C and F clamps. It offers excellent safety and security while performing your tasks.
What are parallel clamps?
The woodworking parallel clamps provide you with large opening capacities. They are basically used in woodworking where the clamp jaws stay parallel underneath increased loads that result in giving a larger distribution area while preventing dimples in the workpiece.
- Large opening capacities
Things to consider:
It is essential to have perfectly parallel bars that can keep your work-pieces secure without damaging them. You will place the piece between the bars and you have to pay attention to this point. When looking for clams, you have to check if the bars are parallel perfectly. The bars can bend sometimes because of shipping or packaging errors, so checking is essential.
Clamps hold no value if they fail to do the jobs they are supposed to do: that’s clamping. If the clamps do not hold things in place for a longer period or even not at all, then it means, the clamping power a crap. So, look for clamps that will have enough power that you want for the projects.
It is expected that a parallel clamp review will come with a clamping power of more than 1000lbs. So, the ones below the range may prove to be problematic.
Also, check the mechanisms that will help in keeping the clamps engaged. There are some manufacturers that offer clamps made of plastic. And this can be a vital factor to understand that the clamps will be a disappointment.
Even, if you look for a plastic clamp then make sure you check the reviews. If the clamps have complaints about getting snapped, then it’s a sign that they will fail to live up to their clamping power.
As we have already mentioned, that material plays an essential role when it comes to clamping power. While plastic may disappoint you in this case, other materials will be there to provide you with great performance.
There are cast iron and steel parallel clamps that will be very solid and long-lasting. Plus, you will also find them having enough strength to withstand the very high pressure required to keep heavy and large planks in position.
You will also require solid parallel clamps for support. In this case, you can think of having aluminum clamps that offer both durability and heavy use. Albeit, such clamps will be pretty pricey but they will be worth buying.
Plastic ones can be ideal for light use, but surely not for heavy-duty projects.
It’s normal to want your clamps to be large in size so you can use them for your projects for a longer time. But here’s the thing, too large clamps will not bring convenience but trouble. The larger-sized clamps are likely to be unwieldy. And this can make it even tougher to maneuver the clamps into the appropriate positions on awkward or smaller projects.
However, this is not very true for all the cases. But you have to ensure that majority of the projects go well with the clamp size you will work with.
Moreover, you will find 2 different measurements when it comes to the clamps. The throat depth and the normal opening.
The throat depth covers the distance to the outside of the clamps from the rail. Do check if the throat depth is sufficient for the projects that you will work on when picking such size.
Meanwhile, the nominal opening refers to the distance between 2 gripping surfaces over the clamp. You should know that you won’t be able to use anything taller than that of the nominal opening.
The design of the jaw is another essential factor to think through. The jaw will help hold your workpiece and ensure safety. So, it has to be enough robust to hold stuff even while applying pressure.
Moreover, the jaw should also be soft and flexible as well so that you can do the job easily without damaging the workpiece.
The spreader comes very handy when you think of spreading your projects rather than squeezing them. As a result, you have to make sure to have the best parallel bar clamps that will come with a spreader function. It will definitely provide you with added convenience.
Make sure to grab the clamps that come with soft rubber pads below the foot. Such features will help in ensuring nonslip clamping and stability.
The clamp handle has to be enough free so you can maneuver it to enjoy a quick clamping experience. Also, make sure that the grip is soft on the handles since it will provide you with comfort.
Mainly, the handle comes in different materials such as metal, plastic, and wood.
One sad thing about the clamps is that the brand offers maneuverability at cost of power. You may have this doubt on a lighter clamp and think that it has been made with inferior materials. And hence, it is expected to lower the maximum power. That’s the reason why you should look for clamps that will be high quality, low cost, and offer maneuverability as well.
Clamps are likely to have a tendency to stretch and damage the surface of the workpiece when they are used to hold it in place. Make sure that you don’t get a bare-metal clamp since it will be a risk to face damages. However, even with a rubber-coated protective pad, it is still possible to damage the surface of the piece. But, such coatings will at least provide the clamps with a degree of forgiveness. Hence, the occurrence of such accidents will be reduced at a greater rate.
Not only that, but it is also essential to look for protection since you will not always see the damage unless you unclamp the tools. So, it will prevent damages in the first place.
