Three basic models of the Stavebolt family are shown here with their associated tension bolts, stitch bolts and various other hardware.

The Small Model, at left, is designed for use in a minimum of 6" x 6" timbers or 7" diameter logs. It measures 1-3/8" x 11" and requires the drilling of an 1-1/2" x 12" hole for its housing. The half inch stitch bolts, which lock it in place, require the drilling of (2) or (3) 9/16" holes, depending on performance requirements. The design loading will affect the number of stitch bolts required and the size of the washer at the head of the 5/8" tension bolt or threaded rod.

The Standard Model, at centre, which was subjected to the NRC/CCMC Evaluation, is designed for use in minimum 8" x 8" timbers or 9" diameter logs. It measures 1-29/32" x 11" and requires the drilling of a 2" x 12" hole for its housing. The 5/8" stitch bolts, which lock it in place, require the drilling of (2) or (3) 11/16" holes, depending on performance requirements. The design loading will affect the number of stitch bolts required and the size of the washer at the head of the 3/4" tension bolt or threaded rod.

The Heavy 4-pin Model, at right, is designed for use in minimum 8" x 8" timbers or 9" diameter logs. It measures 1-29/32" x 13" and requires the drilling of a 2" x 14" hole for its housing. The 5/8" stitch bolts, which lock it in place, require the drilling of (4) 11/16" holes. This high performance unit requires a 4.5" x 4.5" x ½" plate washer at the head of the 3/4" tension bolt or threaded rod to achieve maximum design loads.

Other Custom Models of the device are available on special order. These may include lengthened pipe sections for deeper housings, some with extra holes for hardware crossings and models with left hand thread for turnbuckle-like installations, etc. All models are subjected to the same manufacturing, quality control and proof testing procedures. For custom models, contact the Company directly. See the Applications section on this web site for typical uses.
