B-LINE 4D280ZN – Frequently Asked Questions
1) What are the footprint dimensions of the 4D280ZN post base for anchor layout?
It measures 6 inches by 6 inches with a 4 inch height, so plan on a 6 x 6 inch bearing area on the slab or steel under each post. Weight is 3.8 lb per base, which matters when you are ordering a few dozen for a rooftop or mechanical room frame.
2) Is the electro-plated finish on the 4D280ZN base suitable for outdoor or rooftop use?
The base is steel with an electro-plated (electro-zinc) finish, which is a light indoor-duty coating. It holds up in dry interior mechanical spaces and above ceilings. For exposed rooftop, exterior, or wet and corrosive areas, specify a hot-dip galvanized or stainless 4Dimension base rather than the ZN version.
3) What does a 4D post base actually do in a strut framing assembly?
It is the footing that ends a vertical 4Dimension strut post and transfers the load into the floor, slab, or structural steel. The 4 inch tall body sleeves and secures the post end while the 6 x 6 inch plate spreads the load and gives you room for anchors. It is the base only, so channel, anchors, and the hardware that joins the post to the base are ordered separately.
4) What part number do I order for a zinc-plated 4Dimension post base?
Order Eaton B-Line 4D280ZN. The ZN suffix is the electro-plated steel version of the 4D post base, and that single model is the whole offering here, so there are no size or finish options to select.
