B-LINE BCH21-AB – Frequently Asked Questions

1) Will the B-Line BCH21-AB J-hook mount on 3/8 inch threaded rod, or does it need 1/2 inch?
Either one. The BCH21-AB has a 1/2 inch diameter hole in the bracket, which lets it hang from 3/8 inch or 1/2 inch all-thread. That is what the "cable to ATR" designation means, it attaches to existing threaded rod drops rather than needing its own anchor in the deck.
2) Is the Eaton B-Line BCH21-AB UL listed for data cable support?
It carries a UL/CUL listing. For an inspector on a commercial or institutional job that is usually the question behind "can I hang my cable off this," and the BCH21-AB answers it on the spec line.
3) Can I use this J-hook in a damp area or outdoors?
The BCH21-AB is steel with a pre-galvanized finish, which suits dry interior work such as plenum, ceiling cavity and equipment room cable runs. Pre-galvanized coating is not the choice for wet exterior or corrosive environments, look to a hot-dip galvanized or stainless support for those.
4) Do I need extra hardware to install the BCH21-AB, or does it clamp straight to the rod?
It is a threaded rod mount fastener, so the bracket goes onto the all-thread drop you already have. Plan on the nuts and washers for the rod plus the rod itself, those are not part of the hook. Nothing gets driven into the structure for the hook itself, which is why it is common for retrofits into existing ceilings.
