Damstom 38'' Panel Clamp

Item #
72% 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.

Great Clamps
By far these are the best panel clamps that I ever used. Easy set up and the panel comes out flat as it should. The clamp screws provide excellent clamping pressure. Highly recommend.

Holds the stock while gluing. Watch out for warping but these will decrease or eliminate it.

Work well
I have used these twice and they have worked very well both time. Very little sanding required to make the join invisible.

38" Panel Clamps
They worked very well for the cutting board that I am making. I wish that they were only 24" long but I'm working with it.

joe w on Mar 25, 2018
I've used some old wood/metal clamps that I think were produced by Wood River. They are a bit contrary but can work pretty good. These clamps just look like a better solution.

Jake H on Mar 8, 2018
For better clamp-ups of flat panels. If these work as advertised, it should mean less sanding.
Anthony P on Mar 8, 2018
I have built many projects joining wood where these would have helped, finally getting tools to minimize any bowing

I've got some panels that have a slight twist in it but I don't want to spend too much time truing them up. This looks perfect for the application.

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
What is the max spacing of these clamps?
Duane H on Dec 4, 2015
BEST ANSWER: Used two clamps on a 3/4" x 28"D x 40"L top. Paced clamps about 5-6" from
both ends. Wish that I have had one more clamp. First time I used these clamps.
Will place a clamp at the back end of these clamps to hold them together.
Will wait until I use these clamps one more time to make final judgement
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 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,
