Here is a Hinged Keypad cover.  You could use it for covering anything you want protected.  I had these years ago in a buisness to cover alarm keypads.  They are quality made and have a hinge for opening.  I think they were made my STI in the USA.   They are open backed for covering items.  I have used it to cover a 3 gang swith array.  I don't know if that meets any codes but it kept the weather off it.  They come appart for easy mounting.  The inside covering area is 8"w x 43/8 t x 1 3/4" deep.  The space covering wall would be 96/8 w x 6 1/8" T x 2" deep.  This does not count the hinges.   There are 2 units that are clear and one that is smoked.  Please indicate the one you want.  The pricing is for each one.  Thanks for looking and Enjoy!
