The Woodpeckers CSPC2 CSP Clamps (Model Number: CSPC2) are purpose-built clamps for Woodpeckers Clamping Squares Plus setups when you want corners held dead steady without juggling extra C-clamps or F-style clamps. This is a workholding clamp set designed for panel and case assembly.

The whole idea is simple: the clamps drop into the hole pattern on the Clamping Squares Plus and tighten in place, keeping the square registered while you install fasteners, add internal parts, or just dry-fit a layout. If you build cabinets, boxes, drawer parts, or face-frame style assemblies, this style of clamping keeps your workflow moving because the clamp and the square work as one unit.

On the tightening side, Woodpeckers uses large, easy-to-grip knobs and a fast-running Acme thread. In real use that means you can run the clamp down quickly, then put real pressure on it without fighting the mechanism. When you are doing repetitive corner assemblies, that time savings is noticeable.

The clamping jaw is extruded aluminum and is intended to clamp without marring your stock under normal clamping pressure. That matters when you are assembling pre-sanded parts or plywood panels where you do not want clamp marks telegraphing through your finish.

Capacity is the other big win. The CSP Clamps work with material as thin as 3/16 in and up to 2 in, which covers most shop and jobsite casework, furniture parts, and general woodworking assemblies.

If you already own Clamping Squares Plus, the CSPC2 clamps are the cleanest way to turn them into a fast, repeatable corner clamping system. If you do not, these clamps are still a good reason to look at the Clamping Squares Plus platform, because standard clamps will work with the squares, but they are not as quick or as compact as the drop-in CSP setup.

Woodpeckers CSPC2 CSP Clamps make Clamping Squares Plus actually feel "one-hand" fast.

If you are already using Clamping Squares Plus, these are the clamps that turn them from "nice idea" into a repeatable corner-assembly system.

• Who it's for: Woodworkers doing cabinets, boxes, and panel assemblies who want corners held square without stacking extra clamps everywhere.
• Why it stands out: Drop-in fit to the CSP holes, quick-running Acme thread, and a thickness range that covers most real-world builds.
• Worth knowing: These clamps are designed around the Clamping Squares Plus CSP pattern, so they are not a general replacement for standard clamps on random jigs.

• What thickness can these clamps handle? The CSP Clamps work with material from 3/16 in up to 2 in thick.
• What are these clamps designed to work with? They are designed to lock into the hole pattern on Woodpeckers Clamping Squares Plus (CSP design with 3/8 in holes).
• How many clamps are in the CSPC2 set? CSPC2 includes 4 clamps.
