Compatibility: When making connections with Parapet Anchors, eliminate all possibility of
roll-out. Roll-out 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 Parapet Anchors 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
