As noted in the exploded views, all ProSeries
®
locks use an extension
mechanism that causes the ball bearings to lock or unlock the shackle.
Typically, ProSeries
®
locks are supplied with a non key retaining function
extension. There are five different variations of this extension you may
encounter as shown here.
The 2 right extensions are the original position used in the Weather
Tough
®
, Shrouded, Solid Body Aluminum, and Solid Body Brass locks.
The 2 left extensions are the version used in all Solid Body Steel locks.
The middle extension is used in the 6230.
The differences are in size and/or the location of the projection on the
spring washer. Its position is critical to operation of the lock. The two
positions you will encounter for that projection are shown at the right.
There are three different extensions used for the NRK, (Non Removable
Key), function and they are shown at the right. Care should be taken
to position them correctly within the lock during assembly. Consult the
component parts listings in this manual to determine the actual part
numbers for the extensions.

There are three different types of retainers used in ProSeries
®
locks.
A ring retainer can be found in the IC lock. It is a standard size and is
used to position a retainer plate for the throw member. In the door
hardware locks, a Retainer Plug (PN. 298-0629) is used to position the
door hardware cylinder. A trap door, screw, and nut (not pictured)
are used to position the cylinder in the other version locks, see the
component parts listings for specific part numbers of particular locks.

The door hardware locks require a driver to allow the door hardware
cylinder to drive the extension. There are four driver types available and
they are shown on the right. Shown is the distinctive feature of the driver
that engages the cylinder.
Positioning the driver on the cylinder should always be done to ensure
that the orientation of the driver forms the assembly profile at the right.
