Spring pin with and without cap

A quick learner from portland oregon says:
I need to replace one of these and also need an extra cap. I have the cap identified and in my cart now with floor/ceiling rail attachment clip.

this is my second request for parts - i just sent one for the fixed pin that also goes with this set of doors.

The nylon cap you have looks spot on to our 21-109 and the complete door pin assembly you're showing us is the 21-054. Review both parts and let us know if you have any other questions.
