Cut lever linkages.

Couplers that have the cut lever attached on top are referred to as "top operating" Couplers that have the cut lever attached at the bottom are referred to as "bottom operating". The type E coupler modeled by the EC87 was always available as a bottom operating coupler, even though the top operating version seems to have been preferred initially. Prototype Couplers offers items to assist the modeler in adding these special details.

The BCL87 contains 10 etched brass cut lever linkages. These linkages fit into slots on the bottom of the coupler as shown in the picture. These brass etchings fit the E, SBE, and SE style couplers. The cut levers (not included) should be inserted through this linkage in a manner that allows the coupler to swing from side to side.

Type F couplers are almost always bottom operated and the linkage is mostly hidden by the coupler casting. A "J" shaped small diameter wire can be used to simulate the linkage for these couplers. The Prototype Couplers type F coupler head provides a shallow locating hole for this wire.

For those that desire to model top operating type E couplers, Prototype Couplers offers drilled top coupler castings which will accept lift rings. This option should be ordered at the same time coupler kits are ordered. Lift rings should be installed prior to assembly of the couplers since there is a risk that glue used to attach the rings may also make its way to the locking ball inside the coupler. For this reason, the drilled tops are only an option for kits - not assembled couplers.

Holes in top castings are created with a #80 drill. We recommend either bending your own eyebolts from 0.010" wire or using Grandt Line #5085 eyebolts (or #86085 if you would rather have the equivalent in brass) for this application.
