RNB87K assembly fixture.

If you plan to assemble lots of EC87K kits, you'll want an AFC Assembly Fixture. This fixture is used to hold the coupler together as it is assembled. The AFC is also very handy for holding the coupler if it becomes necessary to thin the shank of the coupler for certain installations. Note that this fixture works for EC87, SBEC87, double shelf, and tightlock couplers, but not short/long shank couplers.

A separate fixture is offered for the RC87K Sharon coupler kit. The AFRC fixture fits only the RC87 style coupler.

The AFN fixture is very useful when assembling EN87K kits.

For the Sharon coupler kits, an assembly fixture is not really an option, but a requirement. The RN87K and RNC87K share the same fixture. The RNB87 requires a different fixture because of its shorter shank.

Spare balls and springs are useful to keep at the workbench. We will replace parts lost during assembly at no charge, but a spare pack lets you carry on without waiting for a replacement. Each pack contains 12 balls and 12 springs.
