Minuteman International CDR-12 8x12in Cast Iron Clean-Out Door | Matte Black Hinged Access Door | Basement & Utility Room Wall Access | Model CDR-12

A heavy-duty 8x12-inch cast iron clean-out door for basements, utility rooms, and fireplace access, finished in matte black.

This Minuteman International clean-out door is built from rugged cast iron with a matte black finish that resists rust and blends into brick, stone, or painted walls. The hinged door features a single-bolt closure for secure, tool-free operation, and the air-tight fiberglass gasket prevents drafts and debris from escaping. Ideal for accessing chimney flues, dryer vents, or plumbing cleanouts, this door is a reliable workhorse for any home maintenance need.

Best for

• Basement or utility room walls where you need occasional access to plumbing, electrical, or HVAC components
• Fireplace clean-out access in masonry or prefab fireplaces, mounted flush with the surrounding wall
• Dryer vent clean-out access in laundry rooms, providing a sealed, insulated door
• Industrial or rustic-style interiors where exposed cast iron adds a utilitarian aesthetic

Not ideal for

• Exterior walls or damp locations - the cast iron can rust if exposed to moisture over time
• High-traffic areas where the door may be bumped frequently - the single-bolt closure is secure but not childproof
• Spaces requiring a fire-rated door - this is a clean-out door, not a fire-rated access panel

Style and finish

The matte black cast iron finish is understated and industrial, complementing brick, stone, or painted drywall. The hinged door and single-bolt closure give it a classic, no-nonsense look that suits traditional and modern utility spaces alike.
