Carpenter's Three-Dimensional Square GEKO 10/90/100 — woodworking angle gauge

The GEKO Carpenter's Three-Dimensional Square 10/90/100 is a woodworking angle gauge designed to provide three fixed reference angles—10°, 90° and 100°—for repetitive checking, marking and alignment in joinery and carpentry tasks. The tool’s three-dimensional shape allows it to be positioned on faces and edges to verify angles, set up workpieces and control assembly fits with consistent orientation. It is intended for use during layout, fitting and repair where stable, repeatable angular references are needed.

Advantages

The GEKO three-dimensional square offers a compact, single-piece solution for quickly checking common angles used in woodworking and joinery. Its fixed angles eliminate the need for repeated measurement with protractors for the specified values, reducing setup time and helping maintain consistent results across multiple workpieces. The tool’s form factor supports edge and face contact for stable placement when marking or aligning components.

Suitable for

• Checking and marking 10°, 90° and 100° angles on wood and composite workpieces
• Aligning joints and edges during assembly and fitting
• Repetitive layout tasks where fixed reference angles speed workflow
• Repair and maintenance tasks requiring quick angle verification

Key specifications

• Fixed reference angles: 10°, 90°, 100°
• Three-dimensional design for face and edge placement
• Intended application: woodworking and joinery angle checking and marking
• Compact size for bench or site use and repeatable positioning

How to use

Place the GEKO three-dimensional square against the workpiece so that the chosen face or edge of the tool sits flush with the surface to be checked or marked. Use the 10°, 90° or 100° face as the reference and trace the edge to mark the angle on the material. For alignment during assembly, position the square between mating parts to verify the correct angle and hold components in place while securing fasteners or adhesives. Ensure the contact surfaces of the tool and workpiece are clean and free of debris for accurate placement.

Использование и уход

Store the tool in a dry place to avoid contamination and check it visually before use. Clean contact surfaces with a cloth to remove dust or sawdust. For extended accuracy, avoid dropping the square or subjecting it to heavy impacts.
