DMM Ultra D Locksafe

A triple-action gate requires three distinct movements—slide, twist, and pull—to open the carabiner. This design significantly reduces the risk of the gate accidentally opening while in use, making it a standard safety requirement for professional work-at-height applications.

The offset D-shape shifts the load toward the spine, which is the strongest part of the carabiner. This geometry also creates a wider gate opening compared to a symmetrical D-shape, making it much easier to clip ropes, slings, or other hardware.

Yes, the Taper Lock nose is specifically engineered to be clean and flush, eliminating the traditional 'hook' found on older carabiners. This prevents the gate from catching on ropes, webbing, or harness gear loops when you are trying to remove it.

Every DMM Ultra D is individually marked with a unique serial number, which allows for full traceability. This is essential for professional gear logs, as it helps you track the carabiner's service history, inspection dates, and lifespan throughout its use.

The carabiner is finished with a high-quality anodized coating that provides excellent corrosion resistance. While it is built for durability, you should still rinse it with fresh water after exposure to saltwater or grit to maintain the smooth operation of the gate mechanism.
