Description
This bundle includes two Onguard RockSolid 8590 key locks, each measuring 89mm by 175mm (15mm shackle diameter). These locks weigh 3 pounds each and feature the X4P locking mechanism, which secures the shackle to the crossbar at four points to resist pulling, jacking, prying, and twisting. The 15mm hardened steel shackle is coated to protect against angle grinders and other attacks.
Each lock uses a bump-proof Z-Cylinder that is resistant to picking, pulling, and drilling. Weather-resistant features include a centered keyway, all-metal end caps, and an automatic keyway cover to improve durability.
The locks come with five keys each and include OnGuard’s anti-theft protection plan, offering up to $5,001 in bicycle theft coverage. These locks hold a security rating of 99 out of 100 and come in black and gray.
