3. COMPATIBILITY
When used as part of a PPE system against falls from a height, this connector must be connected to a
compatible connection (example: a correct D-Ring). It is important to ensure compatibility in order to avoid
possibility of roll-out or disengagement.
Only one personal protective system can be attached to this connector. This connector is designed for use
by one person only.
Ensure that proper fall clearance exists in order to prevent striking ground or other objects in the event of a
fall.
Note: a connector is considered to have a compatible connection when the connectors have been designed
to work together and that their shape/size do not cause gates to inadvertently open. All connections must
fully close and lock.
