The Danco 89172 shower arm flange does exactly what a flange should do — it stays put. The set-screw mounting system secures to 1/2 inch IPS shower arms, and the die-cast metal construction works with Moen, Delta, Kohler, and other standard brands. One reviewer summed it up perfectly: “The old one wouldn’t stay tight. This holds the shower rack in place.”
That’s the entire story. No gimmicks, no premium positioning. Just a metal flange with a set screw that actually works.
The Set-Screw Difference
Most cheap flanges rely on friction fits that loosen over time. The shower arm shifts, the flange slides down, and you’re back to looking at the hole in the wall. Danco’s set-screw mounting provides a secure, non-slip hold. Tighten it once, and it stays where you put it.
The flange measures about 2.69 inches in outer diameter — standard size that covers typical wall penetrations without looking oversized. The chrome-plated finish matches most bathroom fixtures.
The installation takes maybe two minutes. Slide the flange onto the shower arm pipe, position it flush against the wall, then tighten the set-screw until firmly secured. No special tools beyond a small screwdriver.
Why Metal Matters in Montana
Plastic flanges crack. Temperature swings from -30°F to bathroom steam create stress that cheap plastic can’t handle. This die-cast metal construction survives the thermal cycling that defines Montana winters. The metal also resists the constant humidity cycles in bathrooms — important when your shower runs hot while it’s below zero outside.
With over 160 reviews averaging 4.4 stars, contractors have figured out what works. Reviews consistently praise its secure fit and good value. The main complaint? Some users note the set screw is small and requires a specific small flat-head screwdriver. Keep a precision screwdriver set handy.
Who Should Buy This
Perfect for rental properties where you need reliable parts that won’t generate callbacks. Ideal for flipping houses where budget-conscious choices still require quality. Great for any contractor who’s tired of flanges that won’t stay tight.
Skip it if you’re doing high-end remodel work where clients expect decorative flanges with premium finishes. This is utilitarian hardware that does its job without calling attention to itself.
