Please note:
1) The ultimate load is NOT the same as allowable load. Ultimate load is the load at the point of failure. Since point of failure is usually heavily dependent on the roof itself, allowable load
should be calculated by the responsible engineer using the appropriate factor of safety for that job.
2) Thread must be embedded in a rafter or other structural roof member.
3) See IBC for required edge distances.
