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.
