Pins and Keepers
Safety Pins
Confirm that the pins are inspected for damage and in good shape prior to installation. If the keeper is in good shape when installed, any damage noted during the inspection would indicate some type of problem or interference. Check that the keeper is not hard against the shoulder of the pin pocket, but is loose and free to move without binding.
