Reversible Manhole Rings & Drainage Grates
A reversible ring can be set top-flanged or bottom-flanged, so one stock ring covers both installation styles. Bass & Hays stocks reversible cast iron manhole rings and matching drainage grates in 18″, 24″, 30″ and 36″ sizes in Grand Prairie, Texas, with same-day availability on most items.
