If you pull a trailer with your RT, F3T or F3L you should give these Batwings a try.
The front of the trailer is attacked by a lot of debris while riding.
Adding these Batwings to the top of the trailer hitch helps catch a lot of the flying debris and water.
Made of high density Polyethylene, it is built to last to take on the rough stuff.
These are bolted on the flat part of the hitch.
