Questions and Answers
Q: Hi Richard, my name is Mike. I was wondering if you know whether or not we can use the Dorma RTS88 with a wooden header and an ALL glass door. The glass door does not have any trim around it, its all glass and would have some sort of "patch fitting" from what my glass guy is telling m
A: Sure you can do this - how thick is the glass on this door?
Q: 1/2" and the doors are typically about 36" wide x 91" high.
A: Here is the Bill of Materials you will need:

Top of door – PT22 – 833.112.xxx
Bottom of door – PT10 – 833.100.xxx
Floor Pivot – 355.6 – 901.106.001
Floor Pivot Cover – 901.079.xxx

“xxx” is where you call out finish.
