Sometimes less is more, and the MicroLink Carabiner is proof of that. Measuring at about 1 inch tall and 1/2 inch wide, this miniature solution is strategically designed to allow for effortless key attachment and security. Simply clip any metal key, fob, or item with its own split ring (even those micro split rings) onto MicroLink and boom it is secured. The secret to its security is hidden in its unique design. The MicroLink body features a narrow opening and novel gate design, ensuring the gate cannot be accidentally opened for a key to slip out unnoticed. And with strong stainless steel construction in a minimalist no-frills design, MicroLink will keep your keys and other gear secure for years to come.
