B-LINE SB220303YZ – Frequently Asked Questions

1) What comes in the box with the B-Line SB220303YZ auxiliary support channel?
The SB220303YZ ships pre-assembled with the channel, the spacer, and the mounting hardware together, so you are not sourcing spacers or fasteners separately to stand the channel off a wall or structural member. What is not included is the strut fittings, clamps or hangers you plan to attach to the channel face.
2) Is the yellow zinc finish on this B-Line support channel suitable for outdoor or wet locations?
The finish is yellow zinc chromate over steel, which is a plated corrosion coating intended for dry indoor service. For exterior, damp or corrosive environments, specify a hot dip galvanized or stainless channel rather than yellow zinc.
3) What steel is the B-Line auxiliary support channel made from?
It is formed from ASMA A36 steel, a structural carbon steel grade, and finished in zinc chromate. That is the material to quote when a drawing or submittal calls out the channel grade for an auxiliary support.
4) What is an auxiliary support channel used for on an electrical job?
An auxiliary support channel is a short strut section, spaced off a surface, that gives you a mounting rail where the structure itself has no usable attachment point. Electricians use it to pick up conduit straps, boxes, small enclosures and cable hangers. The B-Line version arrives with channel, spacer and hardware already put together, so it goes up as one piece rather than as loose parts assembled in the field.
