I got a frameless slider, installed it myself. Not that hard to
install. With the door system that you have the measurements have to
be spot on.
Its also important what the doors will be supported on. I assume that
they are going right into beams right? Doors were heavy as hell.
(3/8" glass)
One thing to be real careful about is handling the glass. Do NOT bang
it around when installing it. Any hard surface contact can shatter
that glass real easy.
