The Ultra O's symmetrical rope baskets are ideal for assisted breaking devices, pulleys, swivels and shackles. They also give stable loading characteristics, as attachments can self-centre under load with minimal movement from the carabiner.

Oval connectors are popular in rope access and tree care situations where multiple connectors, slings, ropes or even pulleys can be connected. They are equally at home in fall arrest situations or as part of a pre-rigged rescue system. The round basket shape allows any of the connection points to self-centre when weighted - this helps avoid the unnerving click that often happens with a more D-shaped connector. The symmetrical basket mean rotation within systems is not required as they sit comfortably either way round.
