Screen frame rails

The screen is supported by two rails on either side. there is no rail going width-wise on the screen.

Frame rails for screen.

Left rail installed.

Closeup of rail attachment. Self tapping metal screw into the aluminum. Mounted underneath so the rail supports the weight instead of the screws. Doesn't look as nice but it will be more sturdy.
One problem is that the rail blocks the adjustment screw for the mount. I'll have to figure a way around this. I think aligning the lasers before attaching the screen to the rails will be the solution.
















Ooops!



















Rails installed... the right way this time.
