ARGCO 401 Style 2-Piece Aluminum Pendent Escutcheon & Replacement Components
ARGCO 401 Style Aluminum Escutcheons provide corrosion-resistant trim for compatible pendent fire sprinkler installations and are available as complete two-piece cup-and-skirt assemblies or individual replacement components.

This listing includes complete escutcheon assemblies as well as replacement skirts and a replacement 1/2" white cup, allowing the required component to be selected without purchasing a complete assembly when only one piece needs replacement.

401 Style Cup & Skirt Design
The ARGCO 401 Style uses a two-piece design consisting of a cup around the sprinkler piping and a separate skirt that provides the visible finished trim at the ceiling.
This construction allows the two components to move relative to one another, providing adjustment between the sprinkler connection and finished ceiling surface.
The two-piece configuration can also simplify maintenance because compatible cups and skirts are available separately. If only the visible skirt or cup requires replacement, a complete new assembly may not be necessary.
Corrosion-Resistant Aluminum
ARGCO offers its aluminum 401 Style as part of its corrosion-resistant fire sprinkler escutcheon line. Aluminum provides resistance to rust and can be useful where conventional steel trim may be susceptible to corrosion.
The material can be useful for compatible indoor or outdoor sprinkler installations where moisture, humidity, or environmental exposure makes corrosion resistance desirable.
Actual suitability depends on the installation environment and project requirements. Verify the required escutcheon material and finish before ordering.
Aluminum & White Finish Options
Aluminum
- Available as a complete 1/2" IPS assembly
- Replacement skirt available separately
- Corrosion-resistant aluminum construction
- Suitable where a metallic aluminum appearance is desired
White
- Complete 1/2" and 3/4" IPS assemblies included
- White replacement skirt available
- White 1/2" replacement cup available
- Useful for blending with compatible light-colored ceiling finishes
Why Use a Two-Piece Pendent Escutcheon?
A two-piece escutcheon provides adjustable trim around a pendent sprinkler where the sprinkler piping extends through the finished ceiling.
The cup surrounds the sprinkler connection while the skirt provides the visible ceiling cover. Their adjustable relationship helps accommodate differences between the sprinkler fitting location and finished ceiling surface.
This provides a cleaner finished appearance while maintaining access to individual escutcheon components when service or replacement is required.
The escutcheon is a trim component only. It should not be used to support sprinkler piping or compensate for an incorrectly positioned sprinkler.
Typical Applications

- Pendent sprinkler installations
- Commercial buildings
- Institutional facilities
- Industrial facilities
- Compatible residential sprinkler systems
Corrosion-Resistant Trim
- Humid environments
- Compatible outdoor applications

- Finished ceiling applications
Replacement Component Selection
Pay close attention to the component description when selecting a variation from this listing. Not every SKU represents a complete two-piece escutcheon.
4525288, 4525288WH, and 4525288WH-3/4 are complete standard 401 Style escutcheon assemblies containing the cup and skirt.
4525288-SKIRT and 4525288WH-SKIRT are replacement skirts only. A cup is not included with these variations.
4525288WHCUP1/2 is the white aluminum 1/2" IPS replacement cup only. A skirt is not included.
When replacing only one part of an existing escutcheon, verify that the existing assembly is compatible with the selected 401 Style replacement component.
Installation & Maintenance
Verify the required sprinkler IPS size, escutcheon style, component type, and finish before installation.
For a complete assembly, position the cup and skirt according to the sprinkler installation and ceiling configuration. Adjust the two components so the skirt sits properly against the finished ceiling without interfering with the sprinkler.
When replacing only a skirt or cup, inspect the remaining escutcheon component before reuse. Replace components that are bent, damaged, excessively worn, corroded, or otherwise unable to maintain proper positioning.
Do not force an incompatible cup and skirt together, modify the sprinkler, obstruct the sprinkler discharge pattern, or use the escutcheon as structural support.
Fire sprinkler installations should follow the sprinkler manufacturer's requirements, approved system design, applicable NFPA standards, and local codes.
