Help with 21-058 pin

A quick learner from New York says:
Bought the 21-058 pin assemblies which use the 108 plastic guides. The doors are leigh 96 inch metal bifold. All the hardware seems fine and installed ok but the 1/4 pins seem to pull out of the plastic guides when opening doors. Is there any way of keeping the pin snapped into the guide tighter.

Paul from SWISCO responded:

My advice would be to try spraying the track with silicone and see if that helps to keep the pins connected to the nylon guide. A local hardware store should sell silicone spray; we like that over oil since it's less likely to collect dirt and debris.
