(10) Keyed Alike Trailer & Multi Purpose Padlocks w/ 20 Keys, 37KA-10

This listing includes ten (10) padlocks keyed alike (a single key opens all) and twenty keys. The lock also features Bump Stop Technology. APPLICATION: These padlocks are perfect for outdoor use when multiple locks operated by one key are required. The #37 latch lock performs effectively on 1-7/8 and 2 inch couplers and on nearly all standard hasp applications. These locks come with a removable shackle sleeve. With the sleeve removed - It secures coupler latches. With the sleeve attached - It is most suitable for hasps. KEY RETAINING function - prevents the padlock from being left unlocked. PADLOCK FEATURES: Measures 1-9/16" (21mm) wide by 3" (76mm) high. Armored Shackle Guard protects against bolt cutters. Revolving, case-hardened steel shackle sleeve offers resistance to cutting and sawing. Removable shackle sleeve. Sleeve off - Secures coupler latches for openings 9/32" (7mm) in diameter. Sleeve on - Works optimally with hasps, fitting openings 1/2" (13mm) in diameter or larger. Precision pin tumbler mechanism provides resistance to picking. IMPORTANT NOTE: If using this style of lock on a trailer's coupler latch, please note it is NOT recommended for all 2-5/16 couplers. It will fit some 2-5/16 couplers, excluding those where the latch is partially recessed from the coupler's top surface, or where latches are wider than 7/8". ATTENTION: If you order two 10-packs or any multiple of ten, we will automatically key them all the same
