Middle Atlantic Afterset Insert 3IN High - 436-2-3

Middle Atlantic 436-2-3 Round Afterset Insert, 3-Inch High

Overview

The Middle Atlantic 436-2-3 is a 3-inch (76.2 mm) diameter round afterset insert designed for in-floor IPS duct service fitting applications. If you are outfitting a raised-floor or in-floor raceway system and need a clean, compliant finish piece that drops into an existing floor cutout after the primary duct work is set, this is the insert to spec. The 436-2-3 (often searched as 436 2 3) ships as a factory-new, genuine Middle Atlantic component sourced direct — no grey-market, no parallel imports.

TAA compliance is verified for this SKU, which matters when the project falls under federal procurement rules or GSA schedule requirements. That single checkbox eliminates a common RFP blocker on government, municipal, or DOD-adjacent installations without requiring a substitute part.

For integrators speccing Middle Atlantic in-floor system components, the 436-2-3 fits within the broader floor box and service fitting category. If you are planning a full raceway build, review the pathway and cabling planning guide to ensure the afterset insert diameter aligns with your conduit and pull-box layout before ordering. Pairing this insert with compatible cable management accessories keeps the finished floor penetration clean and serviceable.

Key Features

• 3-Inch (76.2 mm) Diameter: sized for standard IPS duct round cutouts — verify your floor box opening matches this diameter before ordering, as afterset inserts are not field-adjustable once the floor finish is applied.
• TAA Compliant: meets Trade Agreements Act requirements, clearing the compliance gate on government and federally-funded projects without a waiver or substitution request.
• Afterset Design: installs after the floor finish is in place, which is the correct sequence for renovation and fit-out projects where the floor surface is completed before service fittings are finalized.
