This strong slide-bolt lock is recommended for use with Miti made wheel immobilizers. The key path is protected by a drill-resistant shield and the body is made of case-hardened chrome-plated stainless steel. This lock is extremely durable and some of our customers have been using the same locks in very intense conditions for years. The keys are in very low circulation which greatly reduces the risk of key duplication versus other locks. Available keyed alike.
