Master Lock 878 975 975LH

Master Lock debuted their new resettable combination padlocks at the Associated Locksmiths of America Convention & Security Expo, July 24th-26th in New Orleans, Louisiana.

Master Lock 975 cutawayThese new padlock models may look similar to the No. 175 and No. 178 combination padlocks but looks can be deceiving, it is what is on the inside that counts. The Master Lock Company has taken great steps innovating the old models to produce the new 878 and 975 models. The dual deadlocking mechanism (pictured to the right) allows for resetting the combination without the use of a combination change tool, such as the K175, which is required for model numbers 175, 176 and 178.

Best of all, instead of being offered in only commercial boxed packaging, each of these new resettable combination padlock models are available in carded packaging for Commercial Showroom Displays [975DCOM, 975DLHCOM]. This helps make these padlocks ideal for the locksmith retail shop that caters to commercial customers.
