Water Resistant Marine Stereo Cover - Smoke Colored Heavy Duty Boat Radio Protector Shield with Flip-up Door & Spring Loaded Release - Mounting Gasket Included - Pyle PLMRCB1

Looks good straight out of the box, fairly chunky appearance but should clear any controls underneath, includes a sticky back foam gasket. Note it doesn't say waterproof on the box, it is water resistant, In my opinion is will probably keep splashes off your stereo but very little else.The hinge has an ingenious spring mechanism inside (Well it would be if it actually worked, the tension is zero, I have tried increasing the tension myself and the spring bends, just lift it by hand), there is a flexible rubber gasket on the face which should not lose its shape easily due to it not actually touching the cover (not sealing) when closed!Not sure what is meant by a support shelf as this is just a cover although the picture on the box shows the twin control type mounting and the instructions show you what to cut away to turn it into a DIN type, mine came as the DIN type already. as mentioned rain and light splashing will probably not get in, and the final mount position for me will be stored under cover.
