I have an area that has Steel Grating that is 1/4" x 1-1/2". The
openings are 15/16" x 3 3/4".
When A.3.3.41.2(2) {2019 ED} states "the thickness of the ceiling
material does not exceed the least dimension of the openings", is this
referring to the depth of the member (1 1/2") or the width between
openings (15/16") or the actual thickness on the material (1/4")?
It's late on a Friday and I'm tired. Thanks for the help.
