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 centre of your panel (which avoids bowing), while applying vertical pressure to keep the faces correctly aligned. That's been true for two OneTIME Tool releases but now, version 3.0 have been improved with more attachment points in the bars and a new scissors joint design that applies almost double the vertical clamping pressure and improves clearance on thicker work. It's the best ClampZILLA ever, and its part of the permanent product line-up at Woodpeckers.

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 edge come together. 

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 their previous design. 

ClampZILLA earned its unusual name when we ran it through some torture testing. It took a three-foot long cheater bar and all of the product developer's strength to break the Acme-threaded clamping screw. Just before failure, ClampZILLA was exerting over 6,500 pounds of clamping pressure. 

ClampZILLA is designed for the long haul. 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 zinc-plated harded steel, except the clamp screw pivot, which is machined from brass. All the machining is done on state-of-the-art CNC equipment at their Strongsville facility.
