The OnGuard Bulldog Combo Mini DT U-Lock combines the convenience of a compact design with the added security of a 4-foot fully coated, braided steel cable. The best-selling Bulldog combo series U-locks offer the same level of security as Bulldog keyed locks, but with the convenience of not having to carry a key. This U-lock provides excellent security with the X2P Double Bolt Locking Mechanism, which locks the shackle on both sides. The 13mm hardened steel shackle resists cutting, prying, and jacking, and the double rubber-coated crossbar cover protects paint and finishes. This lock includes an all-tube mounting bracket.
