S&G CHANGE KEY U12 4-WHEEL STD 6600-6700 SERIES
Product Overview
Suitable for all 4-wheel 6600 and 6700 series combination locks.
Older T8400MP locks required a model 8400 change key, which is now obsolete. These locks can be identified by a change key hole that is flush with the surface of the cover. In most cases, a standard 4-wheel change key can be used as a substitute for the obsolete key.
Key Features
- Gold tone finish.
