Best 6-Inch Cleanout Covers for Drainage and Floor Cleanouts
The best 6-inch cleanout cover depends on whether you need a threaded pipe plug, a visible floor plate, or a replacement cleanout head. The Cinsda and Jeckthun plugs are options for non-pressure DWV drainage systems; the Zurn assembly is designed for certain retrofit applications; and the SUPPLYGIANT plates conceal an existing cleanout opening. Check the opening, connection type, and installation location before choosing.

Cinsda 6-Inch PVC Sewer Cleanout Plug
Best for: Homeowners or contractors looking for a PVC plug for a non-pressure sewer and drain, waste, and vent (DWV) system. This product is described as a component used with 6-inch sewer and drain pipe in drainage systems.
Its listed PVC construction is described as sturdy, with resistance to frost and corrosion and high impact strength. Choose this option when you need a pipe fitting-style cleanout plug rather than a decorative floor cover. It is intended for residential and commercial underground DWV applications.
Limitation: The product information specifies non-pressure use. Confirm the fitting and cleanout adapter connection before installation; this plug is not described as a floor cover plate.
Zurn LC-CR06NI Nickel Bronze Cleanout Head
Best for: Buyers handling a retrofit or replacement where a compatible light commercial modular drain adapter is already installed. The product is a cleanout head assembly, not simply a threaded PVC plug.
The listed Snap-On frame is intended to make the top assembly flexible for retrofit and replacement applications, and the description says it snaps onto existing light commercial modular drain adapters. The nickel bronze top provides a finished appearance and is described as slip-proof. Choose this assembly when the existing drain adapter matches the product’s stated application.
Limitation: The fit depends on the existing adapter. Verify the adapter type and dimensions rather than assuming that every 6-inch cleanout will accept this head.
SUPPLY GIANT 6-Inch Stainless Cover Plate
Best for: Someone who needs to conceal a cleanout hole while keeping the cleanout plug accessible. The stainless steel plate is listed as a floor cleanout cover plate with a chrome finish.
The included 2-1/4-inch nickel-plated bolt is specified for installation. The plate covers the opening where a cleanout plug is located, so the plug can still be reached when maintenance is needed. The manufacturer also lists secondary uses as a wall protector or a way to cover existing wall damage.
Limitation: This is a cover plate, not a replacement pipe plug. Check the opening and bolt arrangement before choosing it, especially if replacing another plate.
SUPPLYGIANT 6-Inch Cleanout Cover Plate
Best for: Buyers seeking a stainless steel plate to conceal a floor cleanout while retaining access to the plug. Like the other SUPPLYGIANT plate, it is also described as usable as a wall protector.
This version includes a 4-inch nickel-plated bolt, which is the key listed difference from the DD006S-F2 plate. Compare the bolt length with the existing installation instead of selecting by the shared 6-inch label alone. The product description says the plate covers the cleanout opening while allowing access when required.
Limitation: The bolt length may not match every cleanout setup. It covers the opening; it does not seal or replace the underlying cleanout plug.
Jeckthun 6-Inch PVC Threaded Cleanout Plug
Best for: Buyers who need a male-threaded PVC cleanout cap for a compatible 6-inch DWV drainage connection. Its listed NPT male thread is intended to connect to standard 6-inch DWV sewer and PVC drain pipes.
The product description identifies residential, commercial, and underground non-pressure drainage applications, and also mentions RV sewer systems. Its PVC construction is described as resistant to cracking, freezing temperatures, and corrosion. Choose it when the threaded connection matches your existing fitting.
Limitation: The description specifies non-pressure DWV use. Confirm the thread and pipe connection before purchase; the stated size alone does not establish compatibility with every cleanout.
Buying Guide: How To Choose A 6-Inch Cleanout Cover
Do you need a plug, a plate, or a head assembly?
A cleanout plug closes the pipe opening and is selected by its connection type and system use. A floor cover plate conceals the opening while leaving the plug accessible. A cleanout head assembly is a replacement top designed for a compatible drain adapter. These parts perform different jobs, so identify which component needs replacement first.
How should you check size and connection?
Measure or confirm the existing fitting and review its connection style. The PVC options describe male-threaded connections, while the Zurn assembly is described as snapping onto certain modular drain adapters. A 6-inch product label does not by itself confirm that threads, adapter, bolt, or opening dimensions will match.
Which material and installation details matter?
For the listed PVC plugs, check that the application is a non-pressure DWV system. For a visible floor opening, compare the cover plate’s bolt length with the installation: the two SUPPLYGIANT listings specify 2-1/4-inch and 4-inch bolts. For retrofit work, confirm the existing adapter is the type described for the Zurn assembly.
Frequently Asked Questions
Is a 6-inch cleanout cover the same as a cleanout plug?
No. A plug closes the pipe connection. A cover plate conceals the opening while allowing access to the plug.
Can these PVC plugs be used in pressurized plumbing?
The Cinsda and Jeckthun product details specify non-pressure DWV use. They do not identify these plugs as suitable for pressurized plumbing.
How do I choose between the two SUPPLYGIANT plates?
Compare the included bolt length with your installation. One listing specifies a 2-1/4-inch bolt; the other specifies a 4-inch bolt.
Will any 6-inch cleanout head fit my existing drain?
Not necessarily. Check the adapter and connection details. The Zurn assembly is described for compatible light commercial modular drain adapters.
