Sioux Chief 832-3DHNRV Ductile Iron Drain Finish Head, 3" Round Strainer with Vandal-Proof Screws

The Sioux Chief 832-3DHNRV is a ductile iron finish head engineered to complete a 3" drain assembly with a round strainer top and vandal-proof (VP) screw attachment. Designed as the visible top component for commercial and institutional floor and area drain bodies, this finish head pairs a durable ductile iron casting with a round strainer pattern (R&S) sized for a 5" neck/body (5NB) opening, giving installers a rugged, field-ready cap for rough-in drainage work. The unit ships with a no-finish surface treatment, leaving the raw ductile iron casting exposed for installations where a painted or plated finish is not required or will be field-coated to match surrounding flooring. As a strainer-style drain head, it is intended to sit flush with the finished floor surface, allowing surface water to pass through the round perforated pattern while keeping debris out of the drain line below. The vandal-proof screw configuration is a key feature for this part number, securing the strainer to the drain body with fasteners that resist unauthorized removal — a common requirement in public restrooms, parking structures, mechanical rooms, and other high-traffic or security-sensitive commercial environments. Because this is a rough-in and finish-level drainage component rather than a decorative fixture, it should be specified and installed by a plumbing contractor familiar with matching strainer finish heads to the correct Sioux Chief drain body platform and neck size. Always confirm that the 3" drain opening and 5NB body dimension align with the installed drain body before ordering, as finish heads are matched components within the Sioux Chief drain system and are not universally interchangeable across all drain bodies.

Key Features

  • Trade Size: Sized for a 3" drain opening with a 5" neck/body (5NB) dimension, matching standard Sioux Chief drain body platforms.
  • Durable Construction: Ductile iron casting provides a rugged, impact-resistant finish head suited to commercial foot traffic and equipment loads.
  • Round Strainer Pattern: R&S round (RND) strainer top allows surface water to drain through while straining out debris before it enters the waste line.
  • Vandal-Proof Attachment: VP screw design secures the strainer to the drain body and resists unauthorized removal, a standard requirement for public and institutional restrooms.
  • No-Finish Surface: Supplied with no applied finish/color, leaving the raw ductile iron casting for field-finishing or unfinished installations.
  • Packaging: Supplied 1 EA for individual rough-in or finish-stage replacement and new-construction use.

Sioux Chief 832-3DHNRV – Frequently Asked Questions

1) Will the Sioux Chief 832-3DHNRV finish head fit any 3 inch floor drain body?
No. The 832-3DHNRV is sized for a 3 inch drain opening with a 5 inch neck/body (5NB) dimension, and finish heads are matched components within the Sioux Chief drain system rather than universal tops. Confirm both the 3 inch drain size and the 5NB neck dimension on the installed body before ordering; a different neck opening will not seat correctly.
2) What does the VP in 832-3DHNRV mean, and why would I specify it on a restroom floor drain?
VP is the vandal-proof screw attachment. The round strainer fastens to the drain body with tamper-resistant screws that resist removal by hand tools, which is why it gets specified for public restrooms, shower rooms, parking structures and mechanical rooms. If tamper resistance is not a requirement, a standard-screw strainer head is the simpler specification.
3) What exactly am I buying with part number 832-3DHNRV, and does it include the drain body?
You are buying the finish head only, the visible top assembly: a round strainer with vandal-proof screws, in ductile iron, for a 3 inch drain with a 5NB neck. It is supplied 1 each. The drain body, clamping ring and any waste piping are separate items, so order those alongside it on new construction.
4) Can I use the 832-3DHNRV as a replacement strainer on an existing floor drain without touching the drain body?
Yes, if the existing body is a Sioux Chief platform with a 3 inch outlet and a 5 inch neck. Replacing just the head is a normal retrofit when the old strainer is broken or has been pried out, and the vandal-proof screws help stop it happening again. If the existing neck is not 5NB, the head will not land flat in the floor and you need the matching size instead.
5) Does the 832-3DHNRV drain head come finished, or do I have to coat it on site?
It ships with no applied finish, so you get the raw ductile iron casting. For installations where the head will be hidden by equipment, in a mechanical room, or field-coated to match the surrounding floor, that is fine. If you need a decorative or plated top to match a finished public space, specify a nickel bronze or coated strainer head instead.
6) Is a ductile iron strainer head strong enough for a parking garage or a floor that sees carts and pallet jacks?
Ductile iron is the reason to pick this one. The casting is impact resistant and rated by the manufacturer for commercial foot traffic and equipment loads, which is why it gets used in parking structures and mechanical rooms. For light-duty interior work a nickel bronze or plastic strainer top would do, but it will not take the same abuse.
7) Should I pick a round strainer or a square one for a tiled shower room floor?
The 832-3DHNRV uses a round (R and S) perforated strainer pattern, which is the usual choice where the drain sets into a sloped mop-sink style or poured floor and the tile is cut around it. Square tops are generally chosen to line up with a tile grid or a trench layout. Function is the same, water passes the perforations and debris is held out of the waste line; the difference is how it reads in the finished floor.
8) Will I need a special driver to install or service the vandal-proof screws on this drain head?
Yes. Vandal-proof fasteners are not standard Phillips or slotted heads, so plan on having the matching tamper-resistant bit on the truck for both the install and any later cleanout of the drain. Without it you cannot lift the strainer, which is the whole point of the VP configuration.
