occurs when interference between a hook and the attachment point causes the hook gate to unintentionally
open and release. All connections must be selected and deemed compatible with Truss Boss Anchor by a
Competent Person. All connector gates must be self-closing and self-locking, and withstand minimum loads of
3,600 lbs. See the following for examples of compatible/incompatible connections:
