Youth Center Questions

A contractor had a question on the interior and exterior door manufacturer specified in Section 08120. Is Kalwall the correct door manufacturer? Do they even manufacture doors or are they a wall systems manufacturer? If they are not the door manufacturer, who is the Series 500IR and Series 500 standard referring to? I could not find anything on the internet about a 500 series door under Kalwal.

These are typos. In Section 08120, page 2, lines 26 and 43, the manufacturer should be Kawneer, not Kalwall.
