iGaging 4in & 6in Double Square Set - 4R Steel Blade, High Precision Woodworking

Overview

The iGaging 4in and 6in Double Square Set brings professional precision to everyday shop tasks. This pair includes two hardened steel double squares with satin chrome finishes, designed to stay accurate through repeated use. Each head can lock securely at any position along the blade, making layout work steadier and faster. The set is built for durability and repeatable results, whether you are aligning cabinet components or laying out precise joints.

Precise graduations you can trust

The blades are graduated in 8ths, 16ths, 32nds, and 64ths, with easy-to-read markings that resist fading. The stated accuracy of 0.0008 inches per inch helps you verify squareness and alignment with confidence, supporting accurate measurements during joinery and alignment tasks. The satin chrome finish reduces glare and provides smooth sliding for quick checks across the workpiece edge.

Two squares, two bases

The 4-inch blade includes a 2.5-inch base, while the 6-inch blade offers a 3.75-inch base. This pairing covers a broad range of tasks—from tight dado work to broader panel layouts. Both blades are heavy-duty hardened steel and precision ground, ensuring a consistent reference surface. The construction supports steady layout work across materials and project sizes.
