Tip Over Post Single Point Anchors

Design Considerations

Tip Over Post Single Point Anchors are designed for pitches of 4:12 and less. Tip Over Post SPA systems include an integral base plate, post, and D-ring anchor designed for attachment of a self retracting lifeline (SRL), lanyard, or a lifeline. The base allows for installation to a variety of roof designs and materials. When subjected to fall arrest forces, the post will tip over to reduce uplifting loads on the roof decking. Unlike Rigid Post Single Point Anchors which are are commonly attached structural steel members beneath the roof deck, Tip Over Post Anchors may be installed with minimal or no penetration of the roof in the case of metal deck, concrete or standing seam metal applications. The minimum required thickness for standing seam metal roofs is 24 gauge. Non-engineered single point anchors must be rated rated at 5,000 for one user or 10,000lbs for two users. Engineered systems must be designed for 2 times the applied load in the event of a fall by a qualified person. A single point anchor may be designed for single or dual tie-off as long as each user attaches to a designated D-Ring. Multiple users should never tie off to the same D-Ring under any circumstances. Special care must be taken to train personnel in the proper use of single point anchors. An SPA is designed to protect workers within a 30 degree conical cone; moving outside the intended coverage area increases the likelihood of coming into contact with structure below the work area in the event of a swing fall.
