▶ Watch the setup demonstration

Four-way pressure

Close the joints. Keep boards aligned.

Side-to-side clamping helps bring board edges together. Top-and-bottom pressure helps keep the panel aligned during glue-up.

Four arrows show side-to-side and top-and-bottom pressure on a panel glue-up.
Pressure mechanism illustration. Body material, clamp length and capacity vary by model.

Bring edges together

Side-to-side pressure helps close the joints between properly prepared boards.

Keep boards aligned

Top-and-bottom pressure helps limit boards lifting out of alignment as you tighten.

Start with prepared stock

Use straight, square edges and dry-fit first. Clamping does not replace flattening or jointing warped stock.

Measure before you choose

Choose by panel width. Plan by panel length.

The size refers to the maximum clamping width across the boards. It is not the length of the finished panel.

  1. Measure the assembled width

    Lay out the boards edge to edge. Choose a clamp with enough capacity for the full width of your glue-up.

  2. Check the stock thickness

    Confirm your boards fall within the thickness range shown here. Dry-fit the complete setup before applying glue.

  3. Support the full panel length

    Use enough clamp positions for your panel length, stock and glue requirements. A pack count is not a guarantee that it suits every project.

Support board alignment

Vertical support helps manage board movement while lateral pressure brings the glue joints together.

Prepare before the glue

A dry run lets you check capacity, board contact and clamp placement while adjustments are easy.

Build on good preparation

Clamping does not replace jointed edges and flat stock. Check alignment as you tighten, without forcing the mechanism.

One series. Four capacities.

Match the clamp to the work you build.

Start with the widest panel you plan to glue. Then check stock thickness and the pack options available for your destination.

Before and after your purchase

A few useful answers before glue-up.

What arrives in the box?

The pack selector above states the number of clamps included. Quantity means packs: two packs of a two-clamp option contain four clamps. Wood, glue and the workbench shown in demonstrations are not included.

Need help with a part or setup?

Keep your order number and model code handy. Send a clear photo of the complete clamp and a close-up of the affected part so the support team can identify the correct version.

Does the size mean panel width or panel length?

It means maximum clamping width across the assembled boards. The length of your panel determines how many clamp positions and supports you need.

S05004: 48 in / 1219 mm
What stock thickness does this model accept?

Use boards within the thickness range shown below for this model. Measure the stock after milling and dry-fit the complete setup before applying glue.

S05004: ¼–3 in / 6.4–76.2 mm
How many clamps should I use?

That depends on panel length, stock stiffness, joint preparation and the adhesive instructions. Dry-fit first and check that pressure and support are adequate along the entire glue-up. Do not assume one pair is suitable for every project.

How many clamps are in a pack, and can I order one or three?

Pack options for this regional listing:

  • 2-clamp pack — Available. Quantity 1 = 2 clamps; quantity 2 = 4 clamps.
  • 1-clamp pack — Available. Quantity 1 = 1 clamp; quantity 2 = 2 clamps.

For one clamp, choose the 1-clamp pack with quantity 1. For three clamps, choose the 1-clamp pack with quantity 3, subject to available stock.

You can also order three clamps by adding one 1-clamp pack and one 2-clamp pack to your cart separately, subject to available stock.

Will these clamps flatten warped boards?

They help support alignment during glue-up, but they do not replace milling or flattening. Prepare straight, flat stock and properly fitting joints before you begin.

What if a handle, bracket or foot is damaged or loose?

Stop using the affected clamp and contact support with your model, order number and photos. Do not force a bent part straight or overtighten to compensate for movement. The team will confirm the next step and part compatibility.

What if a clamp seems to be missing from my package?

Compare the contents with the pack option on your order and inspect the packaging carefully. If the count still does not match, keep the packaging and send support a photo of the contents and shipping label.

What are the shipping and return terms?

Availability and delivery options depend on your destination and the item selected. Check the current shipping and returns policies below for the applicable terms; checkout confirms the shipping charges.

What is the clamp body made from?

Body material refers to the main clamp structure, not every fastener or component. Check the model information below when comparing the series.

I did my first cutting board with the new clamps and I had to do much less sanding. I am very happy with them!

16" panel clamps

This is my first time using a clamp like this. I was checking out some other brands and saw that these had good reviews and the price was right. I've glued up 3 boards so far, and they are very easy and quick to set up! I used some painter's tape on the bottom rail and have little to no cleanup afterwards. I used a scrap piece of wood by the rear pins just to prevent any damage to the finished piece, but don't think it's really necessary. Great clamps! Can't wait to check out more SpeTool products!

A real help

I broke these clamps in on a chaotic board I was making, 7 glue ups. It really does work as well as described. So much so, I am looking to purchase 2 more in the 36" size. Very glad I bought these, looking forward to many more years of flatter glue ups. Thanks SpeTools!

Bracket bends

When you tighten down clamp it tends to bend under pressure. I like the product , I just would like the end brackets to be stronger. I bent it back with a pliers but the strength really isn't there anymore.

Panel Clamps Are Great

Finally started a project where I could use the 24” panel clamps. They are a game changer. Will be ordering some 36” clamps in the near future!

Fantastic

These clamps work amazingly well. Very high quality heavy duty materia and came very well packedl. Fantastic results with super easy clean up. Worked like a champ gluing up some inlay strips. Reasonably priced for what you get. I'll definitely be getting a few more

Great Clammping Experience

I am very impressed with your product. It works as advertised. You still need to not be in a hurry and check all the wood before clamping. I have used all I bought and will continue to do so. Before clamping the wood down the wood make sure it is where you want it and check as you tighten the clamp that it stays level. If you do that it will come out wonderfully. It is possible to eliminate the clamps used to keep everything flat if done properly.

Well made - was hesitant on the price yeah my first set I was sold on it. Money well spent.

Panel Clamps

These clamps are a game changer. I’ve been building cutting boards with them and it has cut my glue up time in half! They make it really easy to square up the ends of the wood and they apply pressure equally front to back and top to bottom. I liked the first set so much, I ordered a second set!! Best money on tools that I’ve spent in a long time…

4 way pressure panel clamps

They seem to work well, have actually only used them once so far. there seemed to be a small bow in them on my project, (a 30x20 table top). Will see if this persists or was something to do with the lumber itself. overall, easy to use, easy to assemble and disassemble, definitely recommend a sacrificial board on the pin end, as they would likely leave a dent in your material otherwise.

Well made, quality build, works very well. Glued up a 2 inch thick solidwood bench top with 15 pieces of hardwood. Clamps kept everything flat. Very pleased. Used french cleats to hang clamps on wall. Only issue is worry about long pin falling out when soring them so i used think wire cables and caribenner clips to attach them. Great product!

These clamps work as advertised. They keep everything perfectly flat and straight. Glue cleans off the clamps easily. Much easier to use than parallel clamps

You have to be kidding? Only one? How the heck do i use ONE? It doesn't come in pairs? OMG! Guess im buying another. So disappointed

I dont care how well you think your homemade glue station clamping is, it will never be as quick,simple and efficient as this system is.

Extremely disappointed! This is my second order for the 24 inch panel clamps. The first order was great but in the last two months they changed their design. It's not just cosmetic, but they are dimensionally different. The initial order was great but the new design is mediocre. Unfortunately the review doesn't allow me to add pictures but their is approximately 1/4 difference in the base. If I'm only using 2 clamps it's not tlan issue but when you combine the panels for a larger glue up 1/2 of the clamps can't sit flat.

spetools 3” clamp system

This clamp is worth the investment. It took away some stress and reduced the number of clamps per glue-up. I make rustic giant wall clocks that are about 36” diameter. These clamps are saving grace!

These are the best clamps I used to date. I have used the rocker ones in the past and these surpass that will definitely be buying more sets for all my glue ups.
