How To Measure For Hitch Receiver Lock Pin Span


What is the significance of the Span of a Hitch Receiver Lock? How do I know what Span I need? I know my Receiver is 2inch - but I dont understand how to pick the right Span?


Expert Reply:

The span you refer to on the etrailer Trailer Hitch Receiver Lock for 2" Hitches # e98880 is the usable length of the pin.

To properly measure for this, you can measure the outside walls of your hitch at the pin hole. If you measured, and got 2-5/8", you'd need a hitch pin with at least a span of 2-5/8" like # e98880,. Additionally, you'd need to measure the diameter of the pin hole, so you can choose the correct diameter pin as well. Usually class I and II hitches have a 1/2" diameter and class III and IV trailer hitches have a 5/8" diameter pin.
