Question:
Hi etrailer, I'm looking at your ball mounts for a 2-1/2" receiver and need one with a 2" ball. I also want a locking hitch pin since my truck sits outside and I'll probably leave the ball mount installed most of the time. Which ball mount and lock should I get?

Hey Adam! You can use the Curt Hitch Lock # C23519 with any of our 10k etrailer ball mounts for 2-1/2" receivers. You'll want to choose from the following based on the amount of drop you need:
-etrailer Ball Mount w/ Pre-Torqued 2" Ball 2" Drop # e68TV
-etrailer Ball Mount w/ Pre-Torqued 2" Ball 4" Drop # e48TV
-etrailer Ball Mount w/ Pre-Torqued 2" Ball 6" Drop # e98TV
The # C23519 has a stainless steel pin so it will hold up well against rust and corrosion when you leave it installed on the truck. The lock uses a quarter-turn design so it's easy to install and remove, and the watertight dust cap helps keep dirt and moisture out of the keyway. It also comes with two keys.

I leave the ball mount in my truck most of the time so I definitely want something that won't rust up. Sounds like the stainless steel lock is worth it.
