This OnGuard high security u-lock provides tenacious protection for all but the most extreme situations. Quattro lock mechanism with dual lockdown protection, pins the beefy 13mm ultra-hardened steel shackle at both ends creating a double lock that can withstand up to 8 tons of pull force while our newly designed m-cylinder provides an added level of security and ease of use. Features include rubber and vinyl coatings to protect painted surfaces and our new all-tube universal mounting bracket that fits virtually any tubing from 20mm to 42mm. Also includes a solid anti-theft protection plan.
