Installation Notes

Installation is typically performed by maintenance technicians, contractors, or experienced DIYers using standard hand tools. Always drill a pilot hole sized to the bolt diameter before driving into wood or structural material, and ensure the substrate is rated to handle the intended load. Torque the hex nut securely against the mounting surface to prevent rotation of the eye under load. Verify that the mounting surface and any attached hardware are rated for the applied load before putting the anchor point into service.
