A.Y. McDonald 74M3AT Rectangular Frame, Model 4174-004

The A.Y. McDonald 74M3AT is a rectangular frame identified by manufacturer part number 4174-004, built for rough-in plumbing and utility access applications where a fixed, rectangular frame opening is required. As with other A.Y. McDonald rough-in components, this frame is manufactured to fit within a coordinated system of covers, boxes, and access assemblies used by plumbing contractors and utility installers. The rectangular (REC) configuration distinguishes it from round frame styles, making it suited to installations where a rectangular access opening is specified by the job or by the mating cover/box assembly it is paired with.

Key Features

  • Rectangular Configuration: The 74M3AT is designed with a rectangular (REC) opening profile rather than a round profile, for use where the job specification or mating cover calls for a rectangular access frame.
  • Manufacturer Part Number: Cross-referenced to A.Y. McDonald part number 4174-004, allowing contractors and distributors to confirm fit and compatibility against A.Y. McDonald's documented product line before ordering.
  • Frame-Only Component: Supplied as a frame component intended to be installed as part of a larger access assembly, consistent with A.Y. McDonald's modular approach to frames and covers used in below-grade and rough-in plumbing work.
  • A.Y. McDonald Sourcing: Sourced directly under the A.Y. McDonald brand name, a long-established manufacturer of water works and plumbing rough-in products used by professional contractors.

A.Y. McDonald 74M3AT – Frequently Asked Questions

1) Is the A.Y. McDonald 74M3AT a round or rectangular frame?
Rectangular. The 74M3AT is built with a rectangular opening profile, not a round one, so it pairs with covers and box assemblies specified for a rectangular access opening. If the job drawing or the mating cover calls for a round frame, this is the wrong configuration.
2) Does the 74M3AT come with a cover, or is it the frame only?
Frame only. The 74M3AT is a single component meant to be installed as part of a larger access assembly, so the mating cover or box is ordered separately and has to match the rectangular opening. Plan the order with the cover in hand if you are building the assembly from scratch.
3) What is the manufacturer part number for the A.Y. McDonald 74M3AT frame?
The 74M3AT cross references to A.Y. McDonald part number 4174-004. Order under that number if your supplier or spec sheet lists the part numerically rather than by the 74M3AT model designation, so you get the rectangular frame configuration and not an adjacent style.
4) What is the A.Y. McDonald 74M3AT frame used for on a plumbing job?
It goes into rough-in and below-grade plumbing access work, the frame-and-cover assemblies used on utility and water works installations. Typical use is new construction and renovation rough-in, plus stock replacement where an existing rectangular frame has to be swapped out.
