Master Lock Commercial Padlock 1-1/2 In H 4 Pin Boron Alloy

Commercial padlock for outdoor security

This Master Lock commercial padlock uses a boron-alloy steel body and a 3/8 in steel shackle with a 1 1/2 in clearance. Four pins and a Master K6000 keyway provide high-security locking for gates, sheds and storage units. The rectangular silver body measures 1 1/2 in high, 2 in wide and 1 in thick with two bumpers for durability. Each lock is keyed differently for individual access control.

Buyers needing weather resistance

This padlock is not weather resistant, so it suits covered or indoor locations rather than exposed marine or coastal sites. The core cannot be swapped or rekeyed, limiting use in master-keyed systems. Users who require a control key or registered key control should look elsewhere. The long shackle helps reach wider hasps but offers no shrouded protection against bolt cutters.

Simple shackle installation with fit checks

Open the lock with its unique key, slide the long shackle through the hasp or chain and snap it shut; no tools are required. The fixed 15/16 in internal width and 1 1/2 in shackle height mean you must verify the mounting points match before purchase. The non-rekeyable cylinder means a lost key requires full lock replacement.
