These padlocks are ideal for all outdoor applications when needing multiple locks that utilize ONLY one key. To fit coupler latch: remove the shackle sleeve. Shackle fits opening of 9/32" (7mm). Note that non-rigid shackle has enough play to fit virtually all coupler latches less than 3/4" wide.

  • This listing is for THREE (3) padlocks keyed alike (same key unlocks all) and six keys. The lock is also available with Bump Stop Technology. Search 37NKA in our storefront.
  • APPLICATION: These padlocks are ideal for all outdoor applications when needing multiple locks that utilize ONLY one key. The #37 latch lock works well on 1-7/8 and 2 inch couplers and on virtually all standard hasp applications. These locks have a removable shackle sleeve. Sleeve off - Secures coupler latches. Sleeve on - Works best with hasps. KEY RETAINING - ensures that padlock is not left unlocked.
  • PADLOCK FEATURES: 1-9/16"(21mm) wide x 3"(76mm) high. Armored Shackle Guard blocks bolt cutters. Revolving, case-hardened steel shackle sleeve resists cutting and sawing. Removable shackle sleeve. Sleeve off - Secures coupler latches to accommodate openings 9/32" (7mm) in diameter. Sleeve on - Works best with hasps, fits openings 1/2" (13mm) in diameter or larger. Precision pin tumbler mechanism resists picking.
  • IMPORTANT NOTE: If using this style lock on a trailers 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.
  • ATTENTION: If you order two 3-packs they will NOT necessarily be keyed the same. To ensure you get two 3-packs keyed alike, you must order the 6-pack.
