Zurn ZS400SSM – Square “Type SSM” Head Assembly with Straight Shank

A polished 6" × 6" stainless steel square head with a Ø110 mm straight shank and a secured, heel-proof, medium-duty strainer—engineered to pair with Z415-series drain bodies for clean looks and dependable performance in finished interiors.

In technical terms, the ZS400SSM is a “Type SSM” head assembly that provides a metric 110 mm straight shank connection and a secured, heel-proof square strainer. In plain English: it’s a durable, stainless top that seats securely in the drain body, stays flush under foot traffic, and complements tile or stone finishes in public spaces.

The secured heel-proof strainer eliminated rocking and the 110 mm straight shank provided a sturdy fit. Post-renovation, facilities reported easier cleaning and fewer maintenance calls related to loose or damaged tops.
