(10) Keyed Alike Multi Purpose Padlocks w/ 20 Keys, 37NKA-10 w/BumpStop Technology

This set contains ten (10) padlocks keyed alike (a single key unlocks every lock) and twenty keys. These locks feature BumpStop Advanced Cylinder Technology. The lock is also offered without BumpStop Technology. APPLICATION: These padlocks are perfect for all outdoor applications requiring multiple locks that use only one key. The #37 latch lock works effectively on 1-7/8 inch and 2 inch couplers and on virtually all standard hasp applications. These locks include a removable shackle sleeve. Sleeve off - Secures coupler latches. Sleeve on - Works best with hasps. TO FIT COUPLER LATCH: Remove the shackle sleeve. The shackle fits a standard opening of 9/32" (7mm). Note that the non-rigid shackle has sufficient play to fit virtually all coupler latches less than 7/8" wide. IMPORTANT NOTE: If using this style lock on a trailer's coupler latch, please be aware it is NOT recommended for all 2-5/16" couplers. It will fit some 2-5/16" couplers, the exception being 2-5/16" couplers that have the latch partially recessed from the top surface of the coupler, or latches that are wider than 7/8". SPECIFICATIONS: The 3/4" (19mm) Armored Shackle Guard helps block bolt cutters. The revolving, case-hardened steel shackle sleeve resists cutting and sawing
