What cross tee’s are used when you are setting up the Sanigrid system to use 2×2 panels versus 2×4 panels?
Reference Sanigrid Technical Data Sheet 6255 and Installation guide 6244. SG223 are used to nest with main runners when the main runners are placed every 24″ (no 48″ cross T’s are used in this combination). SG222 are used to nest into the 48″ Cross T’s SG202 when the Main T’s are every 48″ split by the 48″ Cross T’s.
