A.Y. McDonald 74M3W Rectangular Meter Box Frame

The A.Y. McDonald 74M3W is a Series 20 rectangular (REC) frame component intended for use in below-grade water meter box and valve box assemblies as part of a rough-in water service installation. Identified by A.Y. McDonald under model reference 4174-017, this frame is designed to pair with a matching rectangular cover to provide a finished, load-rated access point at grade for utility and plumbing contractors servicing meter pits, valve boxes, and similar underground access structures. As a trade rough-in component, the 74M3W frame is built for installation behind the finished surface, not as a decorative or homeowner-facing fixture, and is intended to be specified by plumbing and utility contractors as part of a complete meter box or valve box system.

Key Features

  • Frame Component: Functions as the outer frame element of a two-piece frame-and-cover access assembly used in below-grade utility installations.
  • A.Y. McDonald Manufacturing: Produced by A.Y. McDonald, a manufacturer of waterworks, plumbing, and utility rough-in products used by municipal and contractor customers.
  • Rough-In Application: Installed below grade as part of a meter box or valve box assembly, positioned to sit flush with the surrounding surface for future service access.

A.Y. McDonald 74M3W – Frequently Asked Questions

1) Is the A.Y. McDonald 74M3W a complete meter box, or just part of one?
The 74M3W is the frame only. It is the outer frame element of a two-piece frame-and-cover access assembly, so you still need the matching rectangular cover and the meter box or valve box body to finish the installation. Order it as a component of a complete below-grade assembly, not as a standalone box.
2) Will the 74M3W frame fit a round meter pit lid?
No. The 74M3W is built in a rectangular (REC) footprint and is meant to mate with rectangular meter box or valve box assemblies. For a round pit you need a round frame and cover instead.
3) What A.Y. McDonald model number should I reference when ordering the 74M3W frame?
Two identifiers travel with this frame: the catalog designation 74M3W and A.Y. McDonald's model reference 4174-017. Either will get a waterworks counter to the same Series 20 rectangular frame. Quoting both avoids a mix-up with adjacent frames in the line.
4) Does the Series 20 designation matter when matching a frame to an existing cover?
It does. The frame is part of A.Y. McDonald's Series 20 frame line, and the series is what keeps the frame, the cover, and the box body consistent for fit and ordering. If the cover already in the ground is from a different series or a different manufacturer's line, match the series rather than assuming a rectangular lid will seat.
5) Where in the installation does a meter box frame like this sit?
Below grade, behind the finished surface. The frame is set as part of the meter box or valve box assembly and positioned to sit flush with the surrounding surface, giving a finished access point at grade for future service on the water line. It is a rough-in component for plumbing and utility crews, not a finish fixture.
6) Can I use the 74M3W on a valve box, or is it strictly for water meters?
Both. The frame is specified for below-grade water meter box assemblies and for valve box and access pit installations, in new construction as well as utility replacement work. The requirement is that the box it lands on is rectangular and matched to the Series 20 line.
