Sandwiches large, thick panels to hold them flat while drying—no bowing when pressure is applied!

Get perfectly flat panels every time with the Damstom Panel Clamp. With its two straight, parallel bars adjusted to firmly sandwich the panel, you'll completely eliminate the problem of glued panels that buckle and bow under pressure. This makes it an excellent solution for table tops, wide door panels and thick bench tops. Tool-free knobs allow you to adjust the parallel bars to clamp panels from 3/4'' thick to a massive 4-1/2'' thick. Plenty of clearance for the handle makes it easy to wind the clamp closed. Constructed from steel with a powder-coated blue finish and rugged Acme thread.

I already had 2 of these clamps. I decided to do a 10.5' table top so I needed 2 more clamps. These work wonderfully to keep a flat surface when clamping several boards together.

What differences, if any, are there between the Damstom D300 Black Edition Panel Clamp (38 inches) clamp and the Damstom clamp offered exclusively by Rockler? We have the obvious Rockler-blue, but is the material the clamp is constructed of different? What about coating / finish?
Jay A on Jan 12, 2016
BEST ANSWER: The difference, other than the color, is the knobs. The knobs on the Rocker are plastic with a metal thread while the original Damstom Black clamps have metal knobs with a metal thread.
what holds down the opposite side from the clamp. ? does not look like there is a clamp there ??
ROBERT S on Nov 8, 2015
BEST ANSWER: There are two square vertical post with a stop on one side. Shown on the far side of the image. Place them at the far end of the wood you wish to clamp. The turn the adjustable clamp handle to tight and add pressure to the gluing wood. The clamp is also adjustable for different thickness wood. I have used the clamp several times and I am very happy with it.
How many total clamps are in the package? Does it come with just one clamp or two?
Terry B on Oct 30, 2017
BEST ANSWER: the price is for 1 clamp/ u need a minimum 2/i own 3 which handles just about anything i might run into/top
quality primary shop tool. joe/carpenter/50yrs/ret.
What is the max spacing of these clamps?
Duane H on Dec 4, 2015
BEST ANSWER: I have found that in a normal kitchen panel of 29" to 30" long
I have used one per foot with cull's. But with three or more board as in a butcher block top or cutting board I would go with one every 10" with cull's
Hi how much downward pressure do they provide?
Paul C on Mar 11, 2016
BEST ANSWER: Not as much as I would like to see. I always need to add a clamp at the back of the clamp to hold the
bars together and still not satisfied. Easier to use than the 2-way pressure clamp but like them better.
If you do a lot of edge gluing of long or wide material would not recommend.
Is both top and bottom parts considered 1 clamp ?
Brent C on Jun 4, 2016
BEST ANSWER: There are the 2 pieces in the kit. it clamps very well horizontally, but he back side needs 2 small clamps in the back to keep it nice and tight. Also if glueing up cutting boards you have to do alot of work to do to remove the glue squeeze out after you remove the clamps and if the piece is wide you will need a center clamp.
Does glue stick to the clamps?
Daryl R on Nov 13, 2019
BEST ANSWER: I used my clamps just today on a sideboard build, and strangely, ended up with a lot of squeeze out, literally all over my three clamps. Usually, I am quick to wipe off the squeeze out but got distracted today on a phone call for about an hour. Coming back to the build I found the hardened squeeze out running up and down my clamps. With a little warm water and a piece of orbital sandpaper (turned upside down) I easily removed the dried glue. Kind of like using a chisel but without a sharp edge. Truly these clamps are a brute and I love them completely. They clean up from most everything but certain stains, so be careful there. Otherwise, glue (typical woodworker's) isn't a problem at all. Great product. I have 8 of them now.
is this for one clamp or a pair of clamps?
Don H on Sep 28, 2018
BEST ANSWER: I purchased two clamps. A clamp consists of 2 bars , a screw device and a square backing pin.
Just ordered 3. I'll have them in 3 days. Has anyone had issues with not putting enough down pressure? I make American flags and just hoping these cross bars dont bend.
PEKOP on Dec 10, 2019
BEST ANSWER: Cross bars won’t bend. I use these to make tables. Only problem. Make sure you use scrap pieces at each end. Will leave a in dentation on project when tighten. Also don’t over tight do each clamp turns equally at same time. Hope this helps.
Are they made in the USA?
Christopher F on Jul 13, 2019
BEST ANSWER: These clamps are made in Canada. They work very well.
are there longer Damstom clamps? can they be extended?
Scott A on Oct 19, 2016
BEST ANSWER: you want to get greedy with a revolutionary clamp/ make two panels/plate join/or go for length/vs width/i generally
use 1 clamp every 6-8" width. hope this helps. joe/carpenter/50yrs/rt.
i am gluing up 1 by boards 14 1/4" long, 57" long, 30 3/4" long &18 3/4" long.
How many clamps do I need on each?
Pappy on Jul 18, 2016
BEST ANSWER: I do t see any problem with any of the boards with the possible exception of the 57. Presume they are each separate glue ups. You might need two clamp sets side by side to do a proper job on those 57" pieces. Clamps are easy to use and do a nice job. Let set for about s half hour and remove squeeze out - will make finishing tasks easier and better. Hook luck,
I need one for 48 inch wide panel. Is there that size?
Frank A on Dec 12, 2017
BEST ANSWER: Not yet. Currently (Nov 2018) Damstom says they are considering a clamp in the 50-52" range. Hopefully they will release one soon.
