These end caps fit over the end of the quick release ball lock pin and allow the pins to be used in applications where the receiving hole is not within tolerance or is out of round. The receiver caps can replace cotter pins and hitch pins to allow you to take advantage of quick changing and fieldwork without tools.
The caps are made from 300 series stainless steel. The Grip Length Reduction is the amount of pin that is inside the end cap which reduces the useable length of the pin by this amount. The tapped ends allow the user to attach a lanyard to the end cap so it does not get lost while not in use. A stainless button head cap screw is included.
