Product Summary

dormakaba’s QCI200 Series ANSI/BHMA Grade 2 interconnect locks provide single motion egress for standard-duty applications.

When you need options for easy emergency exit, the QCI200 Series offers a lower cost alternative to mortise locks and includes features like an ADA thumb turn to ensure compliance with building codes.

Unlike most interconnect locks, we designed our QCI200 lock with a cylindrical body for more robust performance and better security.

Constructed with top-quality materials and enhanced security functions, QCI200 locks deliver easy-to-use security you can count on.

Product Details

Durable and secure 

Construction features like cylindrical lock bodies, enhanced deadbolts, stainless steel cartridges between levers and deadbolts, and 1” deadbolt latches with hardened steel roller pins make QCI200 series interconnect locks more durable and attack resistant. Features like an ADA thumb turn keep QCI200 locks compliant with current building codes.

SmartKey™ technology

The QCI200 series comes with an optional re-key system, allowing simple re-keying without changing or removing anything from the door.

Better warranties 

With a lifetime mechanical, three-year finish the QCI200 series is backed by industry-leading guarantees.

Easy to retrofit 

Choose a SFIC option or keep existing small format cores and use them with QCI200 series products.

More options 

Add a lock/unlock deadbolt status indicator, and single locking or double locking options.

Simplified installation 

Compartmentalized packaging makes QCI200 locks easier to install, and tapered deadbolt latches make installation on even warped doors much simpler.
