4' Prof. Straight Edge Short
The four foot Professional Straight Edge provides the accuracy needed for making seams in sheet vinyl and like materials. It is precision ground on each of its edges for straightness with accuracy of +/-.003". It establishes straightness along a first edge of a seam so that the other edge can be underscribed using the first edge as a guide. This straight edge is also made of special spring steel that will return to its flat condition even after being bent. It has one end formed at a 45° angle for pattern work, and is painted blue to reduce rust. Dimensions: 4' x 3" x 1/8". Net weight: 4 lbs.
