Plug That Hole!
Color: Black, Size: 1
I have been very pleased with how well this cover is holding up. It fits snugly into the receiver hole and stays put. Makes the back of the car look so much better and keeps dirt out of the receiver. Good Job! PLUS: I don't have to store the plug in the back of the car any longer! Hinged piece is still nice and flexible.

Well constructed! Tight Fit.
Color: Black, Size: 1
Great construction, very durable. A bit tight to install, but that is not necessarily a bad thing. It will certainly keep it from ever falling off.

Good hitch cover
Color: Black, Size: 1
This is a well made,tight fitting hitch cover but the holding strap is too small to go over the hitch lip so I used my wife’s hair dryer to heat it up a skosh and voila! Fit like a charm! I recommend this cover.
