Yes. Our single doors can be fire rated (up to 3 hours) up to and including 4'0" wide x 10'0" high so you are covered for a 3' x 9' door with a 3/4 hour rating.

On a 3/4 hour rating (C Label) you are allowed 1296 square inches of glass max. 9 sguare feet equals exactly 1296 square inches so you are good here as well.

Thanks for your question!
