Product details:
CRL's finest Folding Wood Rule is linked at each joint by a brass plated lock sleeve that protects each joint at the rivet. The top 6" (152 mm) section has a brass slide with graduations which slides out from the edge and is handy for measuring into narrow openings. Brass plated end caps protect the ends from wear. Graduations are in 1/16ths of an inch and the entire Rule is epoxy coated for long life.
