Price Guide (Inc GST): POA

The non-conductive features ensures there is no electrical connection to the key, thus providing further safety for workers, as well as making the locks very light weight at only 72 grams each.

The SLP-550 series matches Cirlock's SLP-450 series with stainless steel shackle. The shackle is 5mm diameter and 50mm long – the Cirlock Australian standard size in lockout padlocks.


  • The locks are available in seven different colours, and can be keyed different, keyed alike and/or master keyed.
  • The Cirlock unique 6 pin cylinder also ensures a very large number of combinations. 'Danger do not remove' and 'belongs to' labels are standard on locks, and/or they can be supplied with 'out of service' labels, company logos, personal names or photo ID or any other labelling as required.
  • All locks and matching keys are uniquely numbered and further engraved information, such as names, can be provided on request.

SLP-550 series padlocks are exclusively made for Cirlock, Australia's original lockout manufacturer. Available through local electrical and other wholesalers.
