The KeyRing MicroLink defines simplicity without compromising key security. This 1” stainless steel split ring is paired with 4 Eyelet MicroLink Carabiners. Each micro carabiner features a small, yet mighty stainless steel body with a unique design and eyelet hole for smooth movement around the ring.Simply clip any metal key, fob, or accessory with its own split ring (even those micro split rings) onto MicroLink and boom—it’s secured. The secret to its security lies in its unique design. The MicroLink body features a narrow opening and novel gate design, ensuring it cannot be accidentally opened for a key to slip out unnoticed. And yet, when it’s time to remove a key for a walk around the block, share a key, or add keys to the mix, you can simply open the MicroLink gate and remove your key. It’s truly that simple.
