CURT safety pins go beyond the simple function of keeping your coupler latch secure. They are constructed from quality materials and have a universal design that allows them be used for a variety of purposes in your towing setup. CURT safety pins are made from solid steel to provide more than enough strength to keep your trailer coupler latched down tight. The zinc plating that we use to finish our safety pins offers excellent protection against rust and corrosion. This is necessary for any trailer because of its frequent exposure to the elements. The user-friendly design of our safety pins allows them to be easily handled while maintaining effective security. This safety pin has a pin diameter of 5/16". CURT safety pins can also be purchased with a 12" chain attachment to mount onto your trailer coupler and prevent the safety pin from being misplaced. Use CURT safety pins for securing trailer couplers, jacks, caster wheels and more. When you couple your trailer to your vehicle, nuts and bolts just do not cut it. Secure your towing equipment right with a safety pin from CURT.

Used to retain wheels on John Deere 60d mower deck. Only needed when installing with auto connect. But larger diameter 1/2 inch would be better. But it works

I use these on my Bulldog couplers and they work perfectly. Good quality part. It's always a good idea to keep a spare.
