A pack of two black Nite Ize S-Biner MicroLocks. The MicroLock is a small double-gated stainless steel S-Biner sized for organising keys and other small items, with a twist-lock plastic lever in the centre: turn it to lock both wire gates so they cannot open by accident, and turn it back to open. That makes it easy to take a single key off your bunch for a run, give one to a mechanic or leave a spare with a friend, without fiddling with split rings. It is also handy for zip pulls, small pouches and torch lanyards. Each MicroLock is made of high-quality stainless steel with stainless wire gates, and the retail card shows a 3 lb (about 1.4 kg) rating.
