6" Plastic Oddities Snap & Lok Drain Leaf Guard (Heavy-Duty Walkout Basement Cover)

Overview

Flat drain grates at the bottom of walkout basement stairs are notorious for clogging with a single layer of wet leaves—causing rainwater to pool on the lower landing and overflow the basement door sill.

This raised, perforated leaf guard solves that problem by giving water multiple elevated entry points along the scalloped rim and side walls, even when leaves pile up around the base. Unlike thin commercial plastic strainers that crack the moment someone steps on them, this cover features internal cross-ribbed support columns with filleted bases that transfer weight directly down to the drain grate below. Printed in ASA, it easily supports a 200 lb adult standing directly on top of it.

Compatibility & Fitment

• Designed For: 6" Plastic Oddities Inc. "Snap & Lok" Series Area Drains (fits the standard 6-inch Snap & Lok strainer found on PSL564, PSL566, and PSL568 models).

• Positive Locking Pins: The four internal support columns feature tip pins spaced to drop directly into the existing holes of the Snap & Lok strainer, locking the guard securely in place so it cannot shift or kick out under foot traffic or heavy runoff.

• Customizing for Other 6" Drains: If you have a different 6-inch drain grate (such as NDS, Sioux Chief, or Oatey), you can easily trim the four locking pins flush or adjust their positions in CAD using the included .STEP file.

Recommended Print Settings

• Orientation: Print upside down with the flat top face directly on the build plate and the scalloped rim and internal cross-rib posts pointing upward. No supports are needed in this orientation.

• Material: ASA (recommended for outdoor UV stability, moisture resistance, and impact strength), ABS, PETG, or PETG-CF. (Avoid standard PLA for outdoor exposure).

• Walls / Perimeters: 4 to 5 walls so the outer shell and internal cross-ribs carry vertical foot-traffic loads cleanly.

• Infill: 25%–35% Gyroid or Cubic.

• Supports: None required.
