Review on Motormic Trailer Hitch Lock - 5/8" Extra Long Black Pin with One Locking System - Includes 1 Safety Clip and 5 Anti-Rattle O-Rings - Fits 2" and 2.5" Tow Receivers (Class III, IV, V) by Tory Richardson

This lock comes with two 1/2" and 5/8" pins so it will fit almost anything. For example, rubber O-rings that take up extra space on the pen. Hard wearing and good power coat finish. The only thing is is a cheap cap that covers the locking part of the pen. The plastic is cheap and very loose. I suspect it will fall off after a few bumps in the road exposing the locking mechanism to mud and water. I taped my cap to the locking mechanism and now the cap is secure.
