Rating:
74% of 100

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.

Good Clamps
I have used three damstom clamps to make two side panels and a top for a large walnut dresser and am very satisfied with them. Setup is fairly easy and I am well pleased with the results. I have no complaints.

Well made, works as advertised
We purchased 6 of these to clamp cabinet door panels and they do the job just fine.

I am suprised by the 30% not so good reviews and can probably add the following.

1.) For the task at hand they are not flimsy, but I would probably not use them for large live edge slabs, or lumber which is crooked and not milled true.

2.) A clamp on the other end is not needed, the technique of how to use them is important. Downward pressure in the center before tightening the front clamp knobs and again downward pressure when applying clamping force flattens and aligns the panels perfectly.

3.) I suspect that the poor reviews eminate from users who tried to clamp panels which are of uneven thickness and slightly warped. Those present a challenge regardless of equipment and methodology.

Great for cutting boards
I've had much better keeping my cutting boards and other flue ups flat with these clamps. Very easy to use and better results than with my parallel clamps.

William W on Jun 9, 2019
I use hand made, wooden boards with clamps to do this, now. It takes a good deal of time to set up, while glue is drying. This should be much faster and better.

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: One.
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.
Are they made in the USA?
Christopher F on Jul 13, 2019
BEST ANSWER: These clamps are made in Canada. They work very well.
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.
are there longer Damstom clamps? can they be extended?
Scott A on Oct 19, 2016
BEST ANSWER: No, that's all the longer they are. You may be able to modify them to make them longer but I have not needed to do that yet, or at this time.
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.
