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 Locksafe gated carabiner that DMM makes and is 14mm shorter than an Ultra O yet still retains a strong construction. Available in standard and removable captive bar versions, with or without iD.

Kwiklock - Auto-locking gate requiring two separate actions to open. Kwiklock gates are suitable when auto-locking gates are a necessity, but rigging systems are relatively static and anchor points are easy to monitor.
Locksafe - An auto-locking gate requiring three separate actions to open. Locksafe gates give extra security in complex rigging systems such as those featuring running ropes or remote anchor points.
Screwgate - Non auto-locking gate which requires two actions to open, and is easy to use with one hand. Screwgates are suitable in systems where anchor points can be easily monitored and are unlikely to be affected by running ropes.
