Lowell LLKRD Alternate Key Lock Set for LDDF Series Racks

The Lowell LLKRD is designed for AV integrators and rack system installers who need independent security across two rack sections within a single LDDF Series dual-door frame. Rather than sharing a single key between both short doors, this alternate lock and key assembly gives each door its own distinct lock cylinder, allowing facilities managers, technicians, or clients to be granted access to one section without exposing the other.

This solution is particularly relevant in installed AV environments where equipment racks serve multiple departments or user groups, such as when one rack section houses broadcast gear and the other holds network or control hardware. Field installation keeps the process straightforward: the original lock stays on one door while the LLKRD replaces the lock on the second door. No special tooling or factory modification is required. If you are specifying an LDDF Series rack installation and security segmentation is a requirement, the LLKRD is the purpose-built answer from Lowell.
