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

Middle Atlantic 436-2-2 Afterset Insert 2-Inch In-Floor Duct Fitting

Overview

The Middle Atlantic 436-2-2 is a 2-inch (50.8 mm) diameter afterset insert designed for use with IPS round duct in-floor service fitting assemblies. Part of Middle Atlantic's in-floor systems line, this fitting slots into an existing floor box or duct opening to provide a clean, finished service point for cable routing — installed after the floor surface is complete, which is the defining advantage of the afterset design. If you're retrofitting a finished floor rather than roughing in during initial construction, the afterset approach eliminates the need to tear up surrounding material.

At 2 inches in diameter, the 436-2-2 fits the standard IPS duct round opening spec. TAA compliance makes it eligible for GSA Schedule purchases and federal facility deployments where Trade Agreements Act conformance is a procurement requirement. For integrators working on government buildings, courthouses, or federally funded projects, TAA status on infrastructure components like floor inserts is a line-item procurement gate — not a feature, but a requirement that either passes or kills a bid.

The afterset form factor suits environments where structured cable management is added to an already-finished space: conference rooms, open office floors, trading floors, or command center installations where raised-access flooring or pre-poured conduit was not part of the original build. Rather than coring a new hole and installing a full flush-mount assembly, the afterset insert drops into a pre-cut or pre-existing 2-inch IPS opening and provides a finished, functional service point.

Middle Atlantic's in-floor system components are designed to work as a coordinated family — inserts, covers, and duct bodies share dimensional standards so field assembly is predictable. The 436-2-2 (often searched as 436 2 2) is the insert element in that system, not a standalone floor box. Verify the mating duct body and cover plate are specified before ordering if you're building out a complete service point from scratch.

Key Features

• 2-Inch (50.8 mm) Diameter: Fits standard IPS round duct openings — the dimensional match is the critical spec to confirm against your floor box or duct body before ordering. A mismatched diameter means the insert either won't seat or will leave a gap.
• Afterset Installation: Designed to install after the floor surface is finished, not during rough-in. This is the right fitting when you're adding cable access to a completed floor without demo work — a meaningful labor and material savings in retrofit projects.
• TAA Compliant: Meets Trade Agreements Act requirements, qualifying this component for TAA-compliant infrastructure projects including federal, state, and GSA-schedule deployments. Verify the full bill of materials for TAA status if your project requires end-to-end compliance.
• Part of Middle Atlantic In-Floor System: Dimensionally coordinated with the broader IPS duct and floor fitting family — covers, duct bodies, and inserts share specs so assembly in the field is consistent and parts interchange predictably across a project.

Integration & Compatibility

The 436-2-2 is compatible with Middle Atlantic's IPS round duct in-floor system components. The 2-inch diameter is the primary compatibility dimension — confirm your floor box, duct body, or existing opening matches before specifying this insert. For floor box and insert compatibility, cross-reference the full Middle Atlantic in-floor systems catalog to identify the correct duct body, cover plate, and any required adapters for your cable type and count.

This fitting is passive infrastructure — it does not carry electrical load or data signaling and requires no power or network connection. It is compatible with any low-voltage or line-voltage cabling that physically fits the 2-inch opening, subject to applicable electrical codes for the installation jurisdiction.

Frequently Asked Questions

Q: Is the Middle Atlantic 436-2-2 TAA compliant?

A: Yes. The 436-2-2 is confirmed TAA compliant, making it eligible for GSA Schedule and federally funded projects that require Trade Agreements Act conformance.

Q: What diameter opening does the 436-2-2 require?

A: The 436-2-2 has a 2-inch (50.8 mm) diameter. Confirm your floor box or IPS duct body matches this dimension before ordering.

Q: What is an afterset insert and how does it differ from a standard flush-mount insert?

A: An afterset insert is designed to be installed after the finished floor surface is in place, dropping into a pre-existing or pre-cut opening. A flush-mount assembly is typically set during rough-in, before the floor surface is applied. The afterset approach is the correct choice for retrofit and renovation work on completed floors.

Q: What Middle Atlantic system does the 436-2-2 belong to?

A: The 436-2-2 is part of Middle Atlantic's IPS (In-Floor Systems) duct round afterset family. It is designed to work with compatible duct bodies and cover plates in that system — it is an insert component, not a complete floor box assembly.

Q: Can the 436-2-2 be used in government or federal facility projects?

A: Yes. TAA compliance means it meets the procurement requirements for most federal and GSA-schedule projects. Always verify the complete bill of materials for TAA status if your contract requires end-to-end compliance across all components.

Jerry Tildsen

The 436-2-2 is one of those components that only matters when it's missing from a punch list — a 2-inch afterset insert sounds trivial until your crew is standing over a finished concrete floor with an IPS duct opening and no insert to close it out. At 50.8 mm, the fit is tight to the IPS spec, and TAA compliance means this isn't a part you swap for an off-brand equivalent on a federal job.

Technical Highlights:

• 2-Inch (50.8 mm) Diameter: Dimensionally matched to Middle Atlantic's IPS round duct system — the fit is by design, not by approximation. Attempting to force a non-spec insert into an IPS duct body risks cracking the duct or leaving an unsealed gap that fails inspection.
• Afterset Design: Installs post-finish-floor — the critical distinction on retrofit and renovation projects where you cannot disturb the surrounding slab or flooring material. Standard flush inserts require pre-pour access; the 436-2-2 does not.
• TAA Compliant: Documented compliance with Trade Agreements Act requirements — a hard procurement gate on GSA and federally funded facility projects. This is not a marketing note; it's a line item your contracting officer will verify.

Deployment Considerations:

• The 436-2-2 is an insert component only — you need the mating duct body and cover plate from the Middle Atlantic IPS family to complete a functional floor service point. Spec the full assembly before submitting a materials list.
• Confirm the finished floor opening was cut or cored to exactly 2 inches. Oversize openings will not hold the insert securely; undersize openings require additional field work that the afterset design is intended to avoid.

The 436-2-2 is the right call on renovation projects in occupied commercial spaces — conference rooms, trading floors, or government office retrofits — where the floor is finished and coring a new rough-in opening is not an option.
