Zurn PN400-5S-GRID Floor Drain Grate 4-5/8"SQ

Covers the exposed floor drain opening while providing multiple pathways for water and other liquids to enter the drainage system. The Zurn PN400-5S-GRID Floor Drain Grate uses a 4-5/8" x 4-5/8" square configuration designed to interface with the applicable drain assembly. Its open-grid surface distributes liquid entry across several drainage passages while helping prevent larger debris from entering directly into the drain. The grate provides structural coverage over the opening while remaining accessible for routine cleaning and maintenance.

Drainage Operation:
Allows surface water to pass through the grid openings and into the underlying drain body. The arrangement of the openings provides distributed flow across the grate rather than concentrating liquid entry at a single point. Keeping the openings clear helps preserve the available drainage area and reduces restrictions caused by accumulated debris. The grate serves as both a drainage interface and a physical barrier between the floor surface and the drain opening.

Drain Opening Coverage:
Provides continuous coverage across the exposed drain opening while maintaining access for liquid movement. The square dimensions establish the physical footprint of the grate within the drain assembly. Proper seating helps distribute contact around the supporting area and reduces unwanted movement during normal use. A correctly positioned grate also helps maintain a consistent transition between the surrounding floor surface and the drain opening.

Replacement Guidelines:
Replace the Floor Drain Grate if it is cracked, broken, bent, deformed, corroded, or no longer fits securely in the drain opening. The part number PN400-5S-GRID and 4-5/8" × 4-5/8" square dimensions should be verified before replacement to ensure the correct floor drain grate is selected. Replace the grate if deterioration affects fit, drainage, surface support, or normal drain operation.

Common Failure Symptoms:

• Visible cracks or fractures in the grate structure.
• Broken or damaged grid sections.
• Bent or deformed grate surface.
• Excessive corrosion or surface deterioration.
• Worn or damaged edges.
• Grate no longer sitting evenly in the drain assembly.
• Loose or unstable grate positioning.

Equipment Compatibility:
The ZURN PN400-5S-GRID Floor Drain Grate should be matched with the applicable Zurn floor drain configuration before purchase. Verify part number PN400-5S-GRID against the existing grate and confirm the applicable drain model using the equipment parts diagram, manufacturer's documentation, or product specifications.
