The Chainlok is a unique device which combines the features of padlocks and interlocks. A durable body and chain made from 316 Stainless Steel makes it suitable for use in the most hostile environments. Chainlok comes with o.5m chain as standard (longer lengths available on request). Flag style ‘Colour Aware Key’ enables incorporation into interlock (key exchange) systems. Flip caps prevent ingress of foreign matter when key is removed.
