Hand Tools
Rules and parallels
Graduated rules, straight edges and parallels
Precision rules, straightedges and parallels for measuring lengths, laying out, and checking the flatness and straightness of surfaces.
They include flexible and rigid graduated rules (with inch and millimeter scales), straight edges with ground edges, and ground and lapped parallels.
Made of hardened steel, they keep their accuracy and finish with continuous use.
