Adjustable length clamp provides pressure from all four sides for big projects like gluing table tops and shelving.

Overview

Adjustable length clamp provides pressure from all four sides — ideal for big projects such as gluing table tops and shelving.
  • Applies pressure on workpiece face when edge-clamping to prevent bowing and buckling large panels.
  • Clamp attaches to any length 2 x 2's (lumber and wood clamp pads not included).
  • One Clamp per Package
  • Includes one set of 2 parts. Two sets shown in photo.
  • See more Info to make wood pieces.


To make wood pieces, drill a series of 5/8" holes spaced 2" apart down the center line of the board face of a 2x4 piece of lumber. Then rip the board lengthwise through the centers of the holes, creating two pieces approx. 1-1/2" x 1-11/16". Rotate the notched boards so that notches are away from each other.

I got another set after my loss to Katrina. Work out a system and the glue up procedure will go smooth. Use wax paper to protect the bars from glue. You don't need a gorilla to tighten the clamps. Shouldn't have tightened so much to break the clamp.

Bought the clamps to make an end grain patterned cutting that I saw in a back issue of Wood Magazine. It did an excellent job of not only the end to end pressure but keeping the board flat! I did make the holes larger in the 2X4 as one review suggested! It was a good idea!
