A.Y. McDonald 74M3WRG Rectangular Meter Box Frame, Size 20

The A.Y. McDonald 74M3WRG is a rectangular (REC) frame designated Size 20, built as a companion component for A.Y. McDonald meter box and curb box assemblies used in water service rough-in work. As a frame, its job is to provide the fixed perimeter structure that a matching lid or cover seats into at grade, giving utility crews and contractors a stable, repeatable fit when a box is opened for meter reading, curb stop access, or service maintenance. Frames of this type are installed below grade or at finished grade as part of the water meter box or curb stop box assembly and are selected to match the box and lid family they are paired with. Because this listing covers the frame component specifically, it is intended to be ordered alongside a compatible A.Y. McDonald box and lid rather than as a standalone enclosure.

Key Features

  • Frame Component: Supplied as a dedicated frame for use with a matching A.Y. McDonald meter box or curb box lid assembly.
  • Rectangular Profile: REC (rectangular) shape designed to correspond with rectangular box and lid openings rather than round configurations.
  • Size 20 Designation: Identified under the manufacturer's Size 20 designation for matching against the correct box and cover family during ordering.
  • Below-Grade Service Use: Intended for installation as part of a below-grade water meter or curb stop box assembly, supporting repeatable access for utility and plumbing crews.
  • A.Y. McDonald Compatibility: Manufactured by A.Y. McDonald for use within its water works box and lid product family.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

  • Water Meter Box Frame Replacement and Assembly
  • Curb Stop Box Access Frame Installations
  • Municipal and Utility Water Service Rough-In
  • Residential and Commercial Underground Service Boxes
  • New Construction and Retrofit Meter Box Repair

Why A.Y. McDonald?

Choosing the correct A.Y. McDonald frame for a given box and lid family supports a proper, repeatable assembly for below-grade water service access.

A.Y. McDonald 74M3WRG – Frequently Asked Questions

1) Is the A.Y. McDonald 74M3WRG a complete meter box, or just the frame?
Frame only. The 74M3WRG is the rectangular perimeter frame that a matching lid seats into at grade; it is not an enclosure on its own. You order it alongside a compatible A.Y. McDonald box and lid from the same family to build a complete below-grade meter or curb stop assembly.
2) Will the 74M3WRG frame fit a round meter box lid?
No. It is a rectangular (REC) profile frame, made to correspond with rectangular box and lid openings. If your box and cover are round, this frame will not seat correctly and you need a round-configuration frame instead.
3) Can I use this frame to repair an existing water meter box without digging out the whole box?
That is one of its intended uses. The 74M3WRG is listed for meter box frame replacement and retrofit meter box repair, as well as new construction rough-in. As long as the existing rectangular box and lid are from the matching A.Y. McDonald Size 20 family, the frame can be swapped as the access component while the box stays in place.
4) What does the Size 20 designation on the A.Y. McDonald 74M3WRG mean when I'm ordering?
Size 20 is A.Y. McDonald's own family designation, and it is the number you match against when pairing the frame with the correct box and cover. Frames, boxes and lids are ordered as a matched set, so confirm the box and lid you already have in the ground carry the same Size 20 rectangular designation before you order the frame on its own.
5) Is the A.Y. McDonald 74M3WRG frame suitable for curb stop access boxes as well as meter boxes?
Yes. It is used on both water meter box and curb stop box assemblies, installed below grade or at finished grade so crews get repeatable access for meter reading, curb stop operation, or service maintenance.
6) What part number do I give my supplier for the A.Y. McDonald rectangular Size 20 frame?
The manufacturer part number is 74M3WRG, from A.Y. McDonald's water works box and lid line. One model covers this frame, so the part number plus the rectangular Size 20 designation is all a counter needs.
