Things to consider before buying a Corner Clamps
There are many brands of corner clamps in the market. Every clamp will serve you the way you want. Some may disappoint you by breaking down after a few uses.
That's why we present the most critical factors that will lead you to the best corner clamp in the market. Don’t forget to check before getting one.
One of the most important factors to consider before buying a corner clamp is clamping power. You should go for a brand of Corner clamp that can firmly and securely hold objects in place.
If it doesn't, then you may find working with it very difficult, and the value of your corner clamp would be lost. Brands that are constructed with good materials such as cast iron and steel have more strength to hold objects in place and are very durable.
So analyze your projects very well and opt for a corner clamp that can hold down large and heavy materials in place while you work on them.
Large corner clamps are suitable for big and heavy woods but ensure you go for a brand that is not too large. Very large corner clamp cannot be easily maneuvered and would not be suited for smaller wood projects.
Medium-sized corner clamps can be easily positioned for smaller wood projects. You should also analyze the throat depth of the corner clamp and ensure it is sufficient for your project before purchasing.
Opt for a corner clamp that offers adequate material protection because corner clamps can stretch or damage the surfaces of the materials they hold. Therefore you should opt for a clamp that has a protective pad coating. This would ensure that your material surface does not get damaged or roughed up.
Clamp Jaw capacity
Clamp jaw capacity/opening are among the first things you should watch out for before purchasing a corner clamp. If the jaw capacity is not wide enough, then your clamp may not be open up to hold down thick materials.
The jaw capacity is usually measured in millimeters or inches, and the wider it is, the better for your project. Even if your current project material is flat, it is necessary to purchase a corner clamp that has a wide jaw capacity for future projects. 2.7 inches jaw capacity or more is ideal so that you don’t get limited using it only on small metal pieces or woodblocks.
There are basically two types of the handle in corner clamps. The sliding T handle type in clamps has a T design. The T design handle allows a user to apply high torque, which would let the jaws to have a high clamping pressure and a tight grip.
But the T handle design lacks soft padding and can be uncomfortable to use. The other type of handle is the soft rubber handle that is very comfortable and easy to use but lacks the T handle design.
So exerting high clamping pressure on the material would be impossible with the rubber handle design type. However, you can still tighten the rubber handle design to apply torque and push the jaws of the clamp firmly into the object. Therefore you should opt for the rubber handle clamp design.
The weight of the corner clamp is important for transportation and general mobility. If you are a workman and you need to carry your tools and equipment from one place to another, then you should consider corner clamps that are not too heavy.
But ensure you do not purchase a lightweight corner clamp because most of the lightweight design has no strength or durability.
The construction of the corner clamp is one of the most important factors to consider when buying a clamp. Corner clamps come in two types of design, which are swing jaw design and a double jaw design. The swing jaw design is very compact and can easily fit in tight spaces.
However, it has a lot of swivel points that bring about a lot of moving parts. This can affect the integrity and strength of the corner clamp. The double jaw corner clamp design is a little bit bigger in size than the swing design. But it has a grid structure that makes the clamp very durable and strong.
Both design types can clamp objects with different thicknesses, but the Double jaw design has a little more advantage, so you should opt for it. Ensure that the corner clamp is made with good material because poor quality material would lead to the failure of the corner clamp.
A good corner clamp should have a variety of uses. They should be suited for woodworking, metal works, framing, doweling, drilling, assembly of cabinets, and lots more.
It should also be accurate and give the workman perfect angles when in use. You should opt for a corner clamp that has a quick setup and accurate adjustments features for ease of use as well.

Making of Joints
Corner clamps can aid in making “T” joints and corner joints. They are used to join materials from the end of one material to another. It is best to use them in pairs when making T joints because one would be used to bind both ends of the board while the other would be used to set the angles.
What Clamps don’t do
Corner clamps would not press a piece of wood to another; instead, they would simply hold pieces of wood next to each other. Pieces of wood would be joined using glue and screws, so you should apply glue to surfaces of wood that would touch.
Position the pieces of your construction material in the clamp very closely
Open the clamp: This is done by twisting the handle counterclockwise and twist until the clamp is wider than the wood or materials pieces you are joining together.
