There's that ONE spot in our game room that could hold an additional pin, except there isn't enough room in front of it to slide the glass off. You know the spot. I bet lots of you have one too. And one additional pin is not a trivial matter when you're an addict.

Why do we still have to slide the glass off that way, I'm wondering? Could someone make a rail mod or maybe manufacturers could start designing the rails (I know, less likely) so that they snap open upward-like? Then the glass could basically be lifted out (or still slid out if you really want to be retro about it). It'd still have the lock bar keeping it from sliding out of course. I know those rails come off for powder-coating and such, so they could be replaced with modded ones if such a thing existed.

The awkward little dance you do, half bent over, getting the glass into the slots to slide in is just embarrassing. We are better than this!

Is there something structurally I'm missing that would make this impossible?

For a game with a shaker you might, to keep it from rattling, but if it were sitting on a soft or insulating strip of some kind, maybe not. On the other hand, if there were no top piece of metal rail holding the glass on, what would it even rattle against?

That's pretty much what I was envisioning, spot on. Just rails with the top part hinged. *wishes*
