Bulldog STD LM U-Lock (8010LM)

The OnGuard Bulldog STD LM U-Lock is built for durability and convenience, balancing a strong 13 mm hardened steel shackle with a practical mid-size locking area. The X2P Double Bolt mechanism secures both sides of the shackle to resist pulling and prying, while the Z-Cylinder core helps prevent bumping, drilling, and picking attempts. Rubber-coated crossbar surfaces protect your bike’s paint from scratches, and the versatile shackle size makes it easy to secure bikes to racks, posts, and railings in urban environments. Includes five laser-cut keys and a universal mounting bracket for convenient on-bike storage. Dimensions: 115 x 230 mm (4.53 x 9.06").
