Of course you want to keep your trailer securely locked to your vehicle — but what about securing your uncoupled trailer at home? Reese’s universal coupler lock fits into the ball socket on your trailer tongue, and locking it prevents the trailer from getting hitched to a vehicle.
Constructed from cast steel, the coupler lock incorporates an advanced locking mechanism that resists picking and prying.
Reese coats the locking bar with zinc to resist corrosion, but there’s no mention what that yellow coating on the body is. Six locking positions and an undersized ball allow the universal coupler lock to work with couplers for 1-7/8″, 2″, and 2-5/16″ balls.
If you look closely you’ll notice the Smith & Wesson branding on the side. Smith & Wesson puts their name on a lot of different products, but I can’t find any reference to this coupler lock on their site.
Regardless of the branding, the universal coupler lock will run you about $20.
