Angle Accessory

A handy add-on that works with the GRS-16 and MTR-18

Compatible with our GRS-16 and GRS-16 PE Guide Rail Squares and the MTR-18 Precision System Triangle, the Angle Accessory extends the usefulness of your tools. When used with the GRS-16 or GRS-16 PE, the angle effectively extends the reference edge of your square to address challenging applications. When used with the MTR-18, the angle can be clamped to square the interior of a cabinet or confirm squareness in many different glue-up/assembly scenarios.

GRS Family: Extend the Reference Edge

If you frequently cut workpieces with edge details like chamfers, radii or other profiles, you may find the reference edge of the guide rail square isn't quite thick enough to rest against the true edge of your workpiece. To solve this dilemma economically, we've created a simple solution: a precision aluminum angle that attaches to the accessory mounting holes on our GRS-16 and GRS-16 PE guide rail squares. Once attached, the effective thickness of the guide rail square is extended to 1-7/8" (47.6 mm) thick and the effective reference edge length extends up to 21.7" (552 mm), allowing you to quickly achieve accurate cuts on otherwise difficult-to-square workpieces.

MTR-18 Triangle: Use as Clamping Angles

Transform your MTR-18 Precision System Triangle into a large, extremely accurate clamping square by adding two Angle Accessories. Easily square a cabinet during glue-up, or hold a miter joint or butt joint at a perfect 90 degrees. Once attached to the face of the MTR-18, the Angle Accessory provides a generous 1.38" (34.9 mm) of clamping surface.

Available in Two Sizes

The Angle Accessory is available in two sizes: small (7" or 177.8 mm long) and large (15" or 381 mm long). When used with the GRS-16 family, both angles are effective at extending the depth of your guide rail square but the larger size is better if you are working with edges that feature natural variation (e.g. live edges), and the added reference edge length makes your cuts even more accurate. When used with the MTR-18, both sizes work great but the large size does provide more real estate for clamps.

The Angle Accessory includes two stainless steel socket head screws for mounting to your guide rail or triangle.

The Angle Accessory is also compatible with the previous version GRS-16 and GRS-16 PE. If you are not sure if your model supports the Angle Accessory, look for the accessory mounting holes on either side of the GRS-16 label, measuring 100 mm apart on centers.

The Angle Accessory is not compatible with the PTR-18 Precision Basic Traingle as it lacks the appropriate mounting holes.
