Key Features
4-Way Pressure This panel clamp squeezes from both sides while also pushing faces into alignment. That means flatter glue-ups with less fighting, less bowing, and less cleanup after the clamps come off. Self-Centering Action The scissors-joint design focuses lateral pressure at the center of the panel. That matters on wide glue-ups where uneven force can pull boards out of line. Better for Thick Work Version 3.0 adds more attachment points in the bars and a revised scissors joint. You get stronger vertical clamping pressure and better clearance when the stock gets thicker.
Overview
Woodpeckers ClampZILLA 3.0 4-Way Panel Clamp is built for woodworkers who want flatter, straighter panel glue-ups with less wrestling at the bench. This is a 4-way panel clamp designed for panel glue-ups, table tops, and other wide edge-glued assemblies. Model Number CLPZ-18-1-22. Instead of only pulling boards together from the edges, it applies lateral pressure to close joints while also applying vertical pressure to keep faces aligned.
The basic idea is simple, but it solves a real problem. Standard bar clamps can close a joint, but they do not do much to keep adjoining boards flush, and they can encourage bowing when pressure is uneven. ClampZILLA uses bars on both sides of the work, tied together by a self-centering scissors joint at both ends. That layout focuses clamping force at the center of the panel, where it does the most good, so you spend less time fixing misalignment after the glue dries.
Woodpeckers updated this version with more attachment points in the bars and a revised scissors-joint design. In practical terms, that means you can tune the setup more easily for the work in front of you, and the clamp delivers substantially more vertical pressure than earlier versions. If you build table tops, cabinet panels, workbench laminations, or other wider glue-ups, that extra downward and upward force is what helps keep the faces from stepping out of plane.
This design is especially useful when the workpiece is thick enough that ordinary clamp setups start getting awkward. The improved clearance on thicker stock gives the clamp more real-world range in a furniture or cabinet shop. It is not just about squeezing harder. It is about applying force in the right directions so the panel stays under control while glue is wet and slippery.
There is also a practical side to the layout. Because the clamp bars sit above and below the work, the system stays organized on the bench and distributes force more evenly across the glue-up. For thinner stock, Woodpeckers notes that you can add flat stock above and below material thinner than 5/8 inch. That gives you a straightforward way to adapt the clamp to lighter panels without giving up the alignment benefit.
The Woodpeckers ClampZILLA 3.0 4-Way Panel Clamp is a good fit for furniture makers, cabinet shops, serious hobby woodworkers, and anyone doing repeat panel work who is tired of chasing board alignment with cauls and extra clamps. If your projects stop at small picture frames, this is probably more clamp than you need. If you regularly glue up tops, doors, shelves, or wider solid-wood panels, this is the kind of clamp that can make the process faster, cleaner, and more predictable.
It is also worth noting that this product is made in the USA. For a shop tool like this, that matters less as a slogan and more as a sign that Woodpeckers built it as a purpose-made woodworking clamp, not a generic clamp adapted to panel work after the fact.
Keep Panels Flat During Glue-Up
Wide glue-ups go sideways fast when pressure is uneven. This clamp system puts bars on both sides of the panel so the pressure stays balanced across the work instead of pulling everything off line.
- Built specifically for panel glue-ups and table top assemblies
- Focused center pressure helps reduce bowing during clamping
More Vertical Pressure Where It Counts
The revised scissors-joint design is not just a mechanical update. It increases vertical clamping force so adjoining boards stay flush, which means less sanding and scraping later.
- Self-centering scissors joints on both ends
- Designed to improve face alignment across multiple boards
Adapt to Thick and Thin Stock
Clamp setups are only useful if they can match the work in front of you. The updated bar layout adds more attachment points, and the design improves clearance on thicker workpieces while still giving you a workable option for thinner panels.
- More attachment points in the bars for setup flexibility
- For stock thinner than 5/8 inch, add flat stock above and below the work

Pro Tip
If you are gluing up stock thinner than 5/8 inch, sandwich the panel with flat stock above and below before tightening the ClampZILLA. It helps the clamp work the way it was designed and keeps lighter material from shifting out of plane.
Tool Nut’s Take
Tool Nut’s Take
Woodpeckers ClampZILLA 3.0 4-Way Panel Clamp Is the Fix for Fussy Glue-Ups
If panel glue-ups are a regular part of your shop time, this clamp solves the two problems that matter most: closing joints and keeping boards flush at the same time.
- Who it’s for: Woodworkers, cabinetmakers, and furniture builders making panels, tops, doors, or shelves from solid stock.
- Why it stands out: The 4-way layout and self-centering scissors joints do more than standard bar clamps, especially when you are trying to keep a wide glue-up flat.
- Worth knowing: This is a purpose-built panel clamp, not a general grab-anything shop clamp. If you do not build panels often, it may be more specialized than you need.
Common Questions
- What is this clamp designed to do? It is designed to clamp panel glue-ups by applying lateral pressure to close joints and vertical pressure to keep board faces aligned.
- What makes ClampZILLA 3.0 different from earlier versions? It adds more attachment points in the bars and uses a revised scissors-joint design that applies nearly double the vertical clamping pressure.
- Can it be used on thicker workpieces? Yes. Woodpeckers states that the updated design improves clearance on thicker work.
- Can it handle thinner material? Yes, with support. For material thinner than 5/8 inch, add flat stock above and below the workpiece.
