40mm solid brass body and 6.5mm diameter brass shackle which are corrosion- and spark-free making them ideal for electricians and engineers. The coloured vinyl casing makes it easy to identify which personnel are working on the equipment. The keyed alike option is useful on multiple site applications where the 'green' electrician can have one key to operate all his green locks, safe in the knowledge that his other colour coded colleagues have completely different keys and cannot switch on the equipment while he is 'locked off'. Lock body and shackle made of solid brass. Double locking, automatic locking. Precision pin cylinder with mushroom counter pins. Paracentric key-way for greater protection against manipulation. Meets standard: DIN EN 12320.
