Guaranteed +/- .002"
The 3D Square is 3/16" aluminum machined to a computer-generated precision of +/- .002" over the full 6" length of the blades. The L-shaped profile is engineered for strength, yet thin enough to allow quick and easy fastening with spring clamps. Bar-clamps or C-clamps can be used where stronger holding power is needed.
Use the 3D Square for building boxes and drawers, for assembly of cabinets and bookcases, or wherever an accurate 90 degree corner is required.
Clamp as many parts as you want
