Sioux Chief 521-558 Double Pipe Eye Suspension Bracket, Galvanized Steel
The Sioux Chief 521-558 Double Pipe Eye Suspension Bracket is a galvanized steel rough-in hanger designed to suspend tubing runs from overhead structural members using a 3/8" threaded rod. This double-hole bracket features 1-11/32" diameter openings sized for use with PipeEye™ insulators, allowing it to cradle CTS copper, PEX, or CPVC tubing without direct metal-to-pipe contact. Built for behind-the-wall and overhead installations, this bracket gives plumbers and contractors a durable, code-ready suspension point for parallel tubing runs in commercial and residential rough-in work.
Key Features
- Double-Hole Configuration: Two 1-11/32" diameter eyes sized for PipeEye™ insulators, allowing a single bracket to support two parallel tubing runs.
- Durable Construction: Manufactured from galvanized steel for corrosion resistance in overhead and concealed rough-in applications.
- Threaded Rod Suspension: Bracket is designed to be suspended using 3/8" threaded rod, giving installers an adjustable overhead mounting point.
- Multi-Material Compatibility: Works with CTS copper, PEX, or CPVC tubing, giving plumbers a single bracket solution across different pipe materials.
- PipeEye™ Insulator Compatible: Designed to pair with PipeEye™ insulators to cushion tubing and help isolate it from the bracket surface.
- Family Hole Options: Part of a bracket series also available with one or four holes, allowing installers to match bracket capacity to the number of tubing runs at a given suspension point.

Sioux Chief 521-558 – Frequently Asked Questions
1) What size threaded rod does the Sioux Chief 521-558 pipe eye bracket hang from?
The 521-558 suspension bracket hangs on 3/8 inch threaded rod, which is the standard rod size for most overhead plumbing hanger work. That lets you set the drop height anywhere you need under a joist or deck insert. The rod itself is a separate purchase.
2) Will the 521-558 bracket work with PEX and CPVC, or is it copper only?
It handles all three. The 521-558 double pipe eye bracket is rated for CTS copper, PEX, and CPVC tubing, so one bracket covers the different materials you may run on the same job. The eyes are sized for PipeEye insulators, which is what keeps the tubing off the bare steel.
3) Do I need to buy insulators separately for the 521-558 bracket?
Yes. The bracket ships as the galvanized steel body only, drilled for two 1-11/32 inch PipeEye insulators. Order the insulators to match your tube size, and the 3/8 inch rod separately. The bracket gives you the suspension point, not the cushioning.
4) How big are the holes in the Sioux Chief double pipe eye bracket?
Two eyes at 1-11/32 inch diameter. That opening is sized around PipeEye insulators rather than bare tube, so the insulator goes in the hole and the tubing sits inside the insulator. If you drop raw tubing straight through you will get metal-to-pipe contact and movement noise.
5) I only have one pipe run at that hanger point, or I have four. Is there a different version?
The pipe eye suspension bracket family comes in one, two, and four hole versions. The 521-558 is the two hole (double) bracket for a pair of parallel runs. Match the hole count to the number of tubes at that suspension point rather than doubling up brackets on one rod.
6) Is a galvanized steel pipe hanger okay for above-ceiling and concealed wall runs?
That is what the 521-558 is built for. Galvanized steel gives it corrosion resistance for overhead and behind-the-wall rough-in, where the bracket gets closed up and never inspected again. Typical use is above-ceiling and in-wall support of parallel copper, PEX, or CPVC runs in both commercial and residential rough-in.
7) How many Sioux Chief 521-558 brackets come in a package?
Packaged 25 each, which suits a rough-in crew hanging a full floor of parallel tubing runs. The part number to order is 521-558 and it is made in the United States.
