Key Features

Square Corners Fast

The Woodpeckers Clamping Squares PLUS & CSP Clamps system keeps casework, panels, and cabinet parts aligned at 90 degrees while you fasten or glue. That means less shifting during assembly and less time fixing a corner that walked out of square.

Drop-In Clamp Setup

The built-in 3/8 inch holes let CSP Clamps drop right into the square instead of fighting separate F-style or C-style clamps. Setup is quicker, cleaner, and easier to manage when you are juggling multiple panels.

Bigger Working Surface

Clamping Square Plus is longer, wider, and stronger than the original design. That extra size gives you better support on larger assemblies where a small corner block just is not enough.

Overview

The Woodpeckers Clamping Squares PLUS & CSP Clamps system is built for woodworkers who want cleaner cabinet assembly, panel layout, and box construction without fighting parts that drift out of square. This is a clamping square and clamp system designed for keeping corners aligned during assembly and fastening. Model CSPRIK1 is part of the Woodpeckers Clamping Square Plus platform, and the whole idea is simple: lock parts at 90 degrees quickly, then keep moving.

What makes this setup different is how the clamp works with the square. Woodpeckers machines a series of 3/8 inch holes into the Clamping Square Plus, then pairs that layout with the CSP Clamp so it drops into position instead of forcing you to reach around the work with separate clamps. On real projects, that saves time and frees up space around the corner. If you build cabinets, drawers, shelving, or utility boxes, that matters right away.

Compared to a basic assembly square, the Clamping Square Plus is described by Woodpeckers as longer, wider, and stronger than the original design. That extra footprint gives you better registration on larger parts and better stability while you drive screws, pin parts together, or let glue set. It is especially useful when you are working with sheet goods and larger case panels where a small corner square does not give you much bearing surface.

The practical benefit is control. When corners stay put, your reveal lines stay consistent, shelves land where they should, and you spend less time checking diagonals after every clamp adjustment. The drop-in clamp format also makes it easier to work around the project instead of stacking a bunch of traditional clamps in the same area and hoping you still have room for a drill or driver.

Woodpeckers also built support around the system. The available CSP Clamp Rack-It stores the setup in one place and is rated to hold up to 4 Clamping Squares Plus and 8 CSP Clamps. For a busy shop, that is not just neat storage. It keeps the squares and clamps together so they are ready when you start glue-up instead of scattered across a bench drawer and a wall cabinet.

This system makes the most sense for cabinet makers, furniture builders, trim carpenters, and serious DIY woodworkers who assemble square boxes and panels on a regular basis. If you only need to square up an occasional picture frame, it is probably more tool than you need. If you build casework often, the Woodpeckers Clamping Squares PLUS & CSP Clamps setup is the kind of shop aid that earns its keep fast because it speeds up assembly and cuts down on rework.

Hold Panels Square While You Work

The main job here is keeping a 90 degree corner from moving while you build. That is what makes this setup useful for cabinet boxes, shelving, and utility casework where one bad corner turns into a twist across the whole assembly.

• Designed to keep large panel projects aligned during assembly
• Lets you fasten, add parts, or dry-fit components while the corner stays square

Faster Clamp Positioning

The built-in hole pattern is what separates this system from using a plain square and random shop clamps. The CSP Clamps drop directly into the square, so you can secure the corner without wrestling bulky clamps around the edge.

• Series of 3/8 inch holes accepts the matching CSP Clamp
• Cleaner setup than separate F-style or C-style clamps at every corner

Keep the System Ready to Go

Shop organization does not sound exciting until glue is open and you are hunting for the last square. The optional Rack-It keeps the whole setup together so the next assembly starts faster.

• Rack-It storage holds up to 4 Clamping Squares Plus and 8 CSP Clamps
• Keeps squares and clamps in one place near the assembly bench

Tool Nut’s Take

Woodpeckers Clamping Squares PLUS & CSP Clamps is the smart way to tame glue-up chaos

If you build boxes and cabinets regularly, this setup solves a real shop problem: keeping corners square without turning the project into a clamp traffic jam.

• Who it’s for: Woodworkers, cabinet makers, and serious DIY builders who assemble square casework often enough to care about speed and repeatability.
• Why it stands out: The drop-in CSP clamp layout is the big win here. It is a cleaner, faster approach than pairing ordinary squares with whatever clamps you have lying around.
• Worth knowing: Model CSPRIK1 sits in a broader Woodpeckers system that also includes storage. That is great for shop workflow, but make sure you confirm the exact configuration you want before checkout.
