The PerfectO is a compact true oval connector that minimises the eye-to-eye length whilst maintaining usability and easy one-handed use. Their shape provides effective centring of loads and the fully rounded rope bearing areas increase carabiner and rope longevity. Its keylock nose allows snag-free operation.

This is the smallest locking carabiner that DMM makes and is 14mm shorter than an Ultra O yet still retains a strong construction.
