Hingepin Kit - Self Locking

This is a caster block hingpin kit that is self locking. It has a flat end on one side and e-clip on the other. These are recommended if you are using bumpstops. Since the top 2-56 screws are now used to hold the bumpstops, we need something else to hold the hingepins in place. These IRS hingepins will hold their position without the need of a 2-56 screw.
