What does the -SF suffix stand for?

#1

I was reading through the latest deliveries on Planespotters.net, and PR-CND was delivered to Connect Linhas Aéreas in April. The type is a Boeing 737-400SF, which I know is a cargo variant. I’m just wondering what the -SF actually stands for.

My guess would be standard body freighter

Or maybe it means special freighter

That exists for the 400 as well…

BCF stands for Boeing Converted Freighter (BCF)

Makes sense. Thanks for the insight!
