Product information & specifications
DMM Vault Lock Harness Clip
Not PPE. The Vault Lock is a tool holder only and must never be used as personal protective equipment or as a load-bearing connector.
The DMM Vault Lock Harness Clip is a secure, durable and highly efficient tool holder designed for professional arborists who need reliable gear organisation on harnesses, kit bags or vehicles. Built from a robust two-part aluminium alloy body and secured with a stainless steel bolt, it offers dependable performance for day-to-day climbing and rigging work.
Available in Grey, Lime and Silver, it's in stock at Gustharts as an authorised DMM dealer, with free UK delivery on this order.
The locking gate mechanism provides additional security by preventing accidental opening, making it ideal for safeguarding essential tools at height. With one-handed operation, a low-profile nose to reduce snagging, and an upper shelf for quick in-situ gear selection, the Vault Lock delivers practical functionality in demanding environments.
