Like all D&D Security Locks, the PullBolt is made from 316-grade stainless steel, making the device ideal for use in marine or corrosive environments. The 3/4” (19mm) diameter lock bolt has a “throw” of 1 1/4” (32mm), and contains a hardened steel insert to resist hacksawing. It is also resistant to prying, oxyacetylene cutting and bolt-cutting.
The locking mechanism is a “deadlock” design, which protects the device from being tampered with or locked without the key-holder’s authority.
The standard 6-pin, key-in-knob style lock cylinders can be keyed alike, master-keyed, or easily replaced by a locksmith with high security cylinders.
