The rigidity, light-weight, and easy handling advantages of the Starrett scriber make it the favorite of log builders everywhere! The features of this scriber include steel construction, forged legs, quadrant, knurled lock nuts and tempered points. This sturdy construction overcomes the possibility of the legs moving with the grain when scribing. The dual vial bubble attachment is fully adjustable. It rotates 360º thus facilitating both vertical and horizontal scribing. The Starrett scriber combined with the rear mount dual vial bubble attachment makes this unit the most popular log scriber we have ever supplied to students, individual home builders and contractors. Since the early 1970's more homes have been built using Starrett scribers than any other scriber. This unit is practically a must for accurate and tight fitting joints.
