The structure I am working with was built in 1958. The roof plans call off a 26L05 long span joist spanning 52'. The SJI 60 yr manual does not include this designation in its loading tables. Does anyone have information on where I could find this "lost" member? Thanks!

Perhaps they meant "LH"? Drafting error?

The LH designation wasn't established until 1962 unfortunately. I contacted SJI and they claim no such member was ever made so I can only conclude that someone screwed up haha.

We ended up just moving the new RTU from midspan of the member to the supporting girder.
