The NS range’s bolt and latch locks are made from copper-brushed aluminium with stainless steel covers. The corrosion-resistant properties of aluminium enable the range to withstand harsh operating conditions.

There are no intermediary components between the NS range’s key and bolt – the key drives the bolt directly. A broken key will prevent the bolt from moving; a defective bolt will trap the key in the lock. This ensures personnel are immediately warned of any fault affecting either the key or locking mechanism, keeping operators safe.
