Woodpeckers ClampZILLA 4-Way Panel Clamp places bars on both sides of your
stock, joined together by a self-centering scissors joint on both ends. ClampZILLA
focuses the lateral pressure on the exact center of your panel (which avoids bowing),
while applying vertical pressure to keep the faces correctly aligned.

In addition to keeping your panels flatter, ClampZILLA saves you both time and
money. You would need 2 regular bar clamps plus 2 “F” clamps and a set of clamping cauls to replace one ClampZILLA 4-Way Panel Clamp. That’s four screws that you have to adjust, while ClampZILLA applies vertical and horizontal pressure simultaneously by simply turning one screw. Your boards move into proper alignment as the edges come together. No more anxiety-filled gluing sessions worrying about the glue starting to set before you get just the right amount of pressure on each clamp.

ClampZILLA’s updated design works with stock from 5/8" to 4". For jobs thinner than 5/8", you can add a piece of 3/4" material above and below your stock and get all the benefits of ClampZILLA’s centered lateral pressure and simultaneous vertical pressure on stock down to 1/4", or even less. End spacers are no longer needed on thick glue-ups and the vertical pressure is almost double that of the earlier design.

The steel bars and clamping pads are
powder-coated for a tough, long-lasting finish…dried glue usually just pops right off. All the clamping mechanism components are machined from stainless steel, except the clamp screw pivot, which is machined from brass. All machining is done on state-of-the-art CNC equipment in Strongsville, Ohio.

ClampZILLA comes in 3 sizes; 18", 38" and 50" capacity. The 50" bars are quite
heavy and long, and can be purchased separately to replace the bars in either the 18" or 38" clamps when you need the extra length.
