DMM Ultra D Locksafe ANSI Carabiner
If you want a connector that’s strong, smooth to handle, and built for serious work, the DMM Ultra D Locksafe ANSI Carabiner is a solid choice. The Triple Action Locksafe mechanism has been a favourite among arborists for years, giving you fast, reliable security that won’t open accidentally. This Ultra D version adds extra gate strength and a generous 16 mm (5/8″) gate opening, making it easy to clip ropes, swivels, lanyards, and hardware even in tight or awkward positions.
The offset D shape is designed to maximise usable space while keeping the load in the strongest part of the carabiner. It’s an excellent option for retractors, lanyards, and a wide range of working-at-height systems. Every unit is individually marked for full traceability, giving you confidence in high-risk environments.
With its strong ratings and solid certifications, this carabiner gives working professionals gear they can count on.
