they are around 2o bucks for hte pair, its basically a plate that has a shaft on it with a rubber thing on the end, there is a spring behind it and it screws into the plate, you rivet it to the door, and when yuo close it, it compresses the spring and when you hit the button on the remote for hte solenoid it aids in "popping" the door out
