Matched sets of couplers and adapters with mechanical keys.

Keyed units will not latch onto standard non-keyed units.
For a particular key code, custom-machined matched
couplers and adapters can latch only onto each other.
Coupler keys are designated as 1C, 2C, 3C, etc., and
adapter keys as 1A, 2A, 3A, etc. So a coupler stamped
with key 1C will connect only with an adapter
stamped with key 1A. When ordering, please specify
key code numbers of your choice.
For 2, 3, and 4 inch size couplings, each coupler and
adapter of the set has an attached key on each side.
of the body. Coupler keys are designated 1F, 2F, 3F,
etc. and the adapter keys 1M, 2M, 3M, etc. These
designations are stamped on the keys themselves.
Keys are field replaceable.
One key (for example, 5F) is fitted to the left-hand
side and one (for example, 4F) to the right-hand side
of a coupler to give the coupler a unique designation
5FL/4FR. The mating adapter for this coupler will have
a unique designation of 5ML/4MR. Each combination
is given a set code, in this case set code T. When
ordering, please specify the set code of your choice.
