That LB apears to have threaded hubs, and is rated for a wet location.
True. That link was provided for completeness sake, and technical enlightenment for any that care to read this additional information. I will absolutely concede that the population of folks interested in that additional information might be quite small. The original poster’s question was already answered in a direct manner in the posts that proceeded that link. The (perhaps sad) fact remains that the installation is compliant, excpet for the non-exposed LB cover.
