Buy a squisher and stop cutting corners. If box offsets are going to save you that much time and make/break the job you are cutting things way too tight. Presentation is eveything and if the inspector sees the effort put in here on the rough, that respect will carry through io the final and onto the next job. Plus, who can't whip in an offset in less than a few seconds, the bender is right there. That was the first thing I learned to bend. Those "buried" conduits in the stud wall going to the sconce box look like junk and if my guys did that, they wouldn't be my guys for long. Sorry it's late and maybe I'm just crabby. I'll give you the Erico fittings are nice and cowboys save you the bend, but I'm not crazy about cowboys either. So to answer the OP, yes we put a box offset everywhere one is needed, no wingin it there!:slaphead:
Its' probably just another sign of my age, but I will say you are "right-on" with that. It's rare that I find a job where offsets were not made, but when I do, I normally find a high percent of deficiencies with the rest of the job. In fairness, I probably inspect more closely when I see a "non-offset" job.
