Welcome! Removing the elastic strap on the side will free it up to drop down. From what I've searched 2 roller hinges....1 each side.....they can easily break. Is there a way to inlay the letters with it attatched? Sorry I'm not more help!
Sorry I couldn't come up with anymore than that. Some other members here might chime in with more info than what I have.....hang tight.....they're usually in and out on a weekend!
