Description

Straps are designed to transfer tension loads in a wide variety of applications.

HRS — heavy strap designed for installation on the edge of 2x members. The HRS416Z installs with Strong-Drive® SDS Heavy-Duty Connector screws.

HTP — heavy tie plate designed for installation on the side of 2x4 or larger members.

LSTA and MSTA — designed for use on the edge of 2x members, with a nailing pattern that reduces the potential for splitting.

LSTI and MSTI — light and medium straps that are suitable where pneumatic nailing is necessary through diaphragm decking and wood chord open-web trusses.

MST — high-capacity strap that can be installed with either nails or bolts. Suitable for double 2x member connections or greater.

MSTC — high-capacity strap that utilizes a staggered nail pattern to help minimize wood splitting. Nail slots have been countersunk to provide a lower nail head profile.
