Help ID this joist
(OP)
Hope someone can help me ID this steel joist.
It looks like a Butler joist with very similar hat channels as chords (with lips) but the end is not quite the same. The joist has square ends and attached to the side of the girder joist.
Also, I was told that Butler's are typically spaced at 5' o.c. These joists are at 6'-4" o.c., 24" deep and 39' long. Location is in Phoenix, AZ.
Attached are some of the pictures. Thanks!

What year was the building built?
Macomber had a system which framed directly into the sides of truss girders with projecting studs on the end of joists that dropped into keyhole slots on the girder.

Al - That's what I'm saying. it's not a butler joist but the hat channel chords are nearly identical to what Butler uses with the lips on the flanges.
No tags on the joists and not sure how old is the building. I would say 1970's.
