The Martindale CABLOK series has been designed for locking off multiple breakers, switches and valves to prevent re-energisation of circuits and systems during maintenance as part of a safe isolation procedure. The flexible multi-stranded steel cable with PVC sheath is easy to thread and can be adjusted to the required length before locking off with a simple squeeze action. The ergonomic designed has a built-in hasp with space for up to six padlocks for when there are multiple operators working on the same system.
