Product Usage: Padlocks

Numbering to "Differ"

To give an improved service, at no extra cost, Iso-Lok can guarantee that padlock locking mechanisms do "differ". Using our simple system of numbering padlock body and keys and registering these numbers in our customer service department, we can avoid using the same numbers on subsequent orders. If, for security reasons, you don't wish the locking number to appear we can still apply the same system for you.

Using the same procedure and in addition to supplying padlocks "to differ", we supply:

Padlocks all "keyed alike" (to pass) Padlocks "master keyed" (mastered and differed) Padlocks with chain attached

This registration of numbers enables us to quickly identify locking mechanisms previously supplied if duplications are required at a later date.

Iso-Lok Keying Options:

Iso-Lok offers three basic keying options with it's safety systems.
