Retain existing lock cases.
Modernize security in a targeted manner.</span>

Many correctional facilities use Mogul locking systems, which have been in reliable service for decades. When individual cylinders reach the end of their service life, replacement parts become increasingly difficult to obtain, or existing components no longer meet current operational requirements, a complete replacement of the locking system is often neither economically nor organizationally feasible.

The HSL MOGUL cylinder from Steinbach &amp; Vollmann was developed as a direct retrofit solution for existing Mogul lock installations. The existing lock case is retained. No extensive door modifications, welding, or major structural alterations are required.

As a result, the retrofit solution enables targeted modernization of the locking technology while preserving the existing infrastructure.

Retrofitting Mogul Cylinders

When the cylinder poses a risk to operations

For locking systems that have been in use for many years, it is not always necessary to replace the entire lock. Often, the only component that needs to be updated is the cylinder.

A complete transition to new lock types can have far-reaching consequences:

  • Modifications to Existing Doors
  • Welding and Metalwork
  • Longer lock-down periods for individual detention rooms or areas
  • increased planning and installation costs
  • additional costs for new lock bodies and hardware

The HSL MOGUL cylinder therefore addresses the areas where modernization is actually needed. The existing lock body is reused and supplemented with cylinder technology developed specifically for the correctional system.

Benefits for Operators
