Rules are used for taking or transferring measurements while straight edges allow drawing lines and testing for straightness. They are used to take accurate measurements while ensuring engineering & construction integrity. Raptor Supplies offers a wide range of rulers & straight edges from brands like General, Westward, Starrett, Johnson, Victor Thermal Dynamics, Klein Tools, Facom, & more. The vast rule and straight edge catalogue includes architect, folding, flexible, wood, steel & pocket rules; as well as diameter tapes and straight edges.

They are marked with arrows at two suspension points for excellent accuracy.
