Product information & specifications
DMM PerfectO Locking Carabiner
The DMM PerfectO Locking Carabiner is a compact, true oval connector designed for arborists, climbers and rope access professionals who need precise, stable connections in a smaller form factor. Engineered to minimise eye-to-eye length while maintaining excellent usability, it's ideal for systems where space, alignment and efficiency are critical.
Available in Screwgate, Kwiklock and Locksafe gate options, with optional captive bar, it's in stock at Gustharts as an authorised DMM dealer.
The symmetrical oval profile keeps loads evenly centred, particularly effective with pulleys, ascenders and rigging devices, improving system stability and reducing unwanted movement. Unlike many lightweight connectors, the PerfectO uses fully rounded rope bearing areas to reduce wear on both carabiner and rope, with I-Beam construction reserved for non-rope-bearing areas to keep strength-to-weight performance high without compromising durability where it matters. As the smallest Locksafe-gated carabiner in the DMM range — 14mm shorter than the Ultra O — it delivers compact performance without sacrificing strength.
Key Features & Benefits
- Compact true oval carabiner for precise system setup
- Minimised eye-to-eye length for efficient rigging
- Symmetrical design for optimal load centring
- Rounded rope bearing surfaces reduce wear on rope and hardware
- Keylock nose for snag-free clipping and removal
- Optional captive bar for secure orientation
- Available in Screwgate, Kwiklock and Locksafe gate options
