- This listing is for TEN (10) padlocks keyed alike (same key unlocks all locks) and twenty keys. These locks feature the BumpStop Advanced Cylinder Technology (for explanation see more product details below). The lock is also available with out Bump Stop Technology. Search 37KA 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.
- TO FIT COUPLER LATCH: Remove the shackle sleeve. Shackle fits standard opening of 9/32" (7mm). Note that non-rigid shackle has enough play to fit virtually all coupler latches less than 7/8 wide.
- 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.
- SPECIFICATIONS: 3/4" (19mm) Armored Shackle Guard helps block bolt cutters. Revolving, case-hardened steel shackle sleeve resists cutting and sawing.
FEATURING BUMP STOP TECHNOLOGY - Lock bumping a surprisingly simple method of breaking in through locked doors and padlocks - is undoubtedly the newest emerging threat to personal property security. And virtually all locks in use today are particularly vulnerable to bumping. Until now. BumpStop Advanced Cylinder Technology employs an innovative, patent pending design which utilizes a unique reverse rake tapered driver pin, high performance springs and tightly machined cylinder chambers. During a bump attempt, this design prevents the transfer of force from the bump key to the pins and therefore blocks rotation of the cylinder so that the lock remains locked.
