The Simpson AHEP is a galvanized hip-end purlin that serves as a lateral restraint and spacer during truss erection. It is specifically designed to attach to the leading edge of step-down hip trusses, eliminating the need for other materials such as drop-top chords, 2x lumber, or gable end fillers. Its unique interlocking design allows for linear installation and maintains framing spacing from eave to hip or peak. The purlin is secured to the roof sheathing or decking with either knurled pneumatic fasteners or low-profile head, self-drilling screws. Its adjustable length makes it suitable for various pitch ranges, from 3/12 to 9/12 as a structural purlin and up to 12/12 as a lateral restraint and spacer during installation.
Key Features
- A structural purlin to which sheathing can be directly attached — no need to remove temporary bracing
- Accurately spaces the installed trusses and helps meet the temporary top-chord lateral restraint recommendations of WTCA/TPI BCSI on step-down hip ends
- Adjustable in length to accommodate a wide pitch range
