Jr Smith 1010D 11-1/8 in High Density Polyethylene Roof Drain Dome

Roof Drain Dome 11-1/8 in

The Jr Smith 1010D is a high-density polyethylene dome designed for 11-1/8 in roof drains. It serves as a protective cover for commercial and residential drainage systems. Plumbers and building maintenance teams use it to prevent debris from entering the drain body. The component is supplied new and ready for installation.

High-density polyethylene construction

The dome material resists corrosion and chemical exposure common in rooftop environments. It maintains structural integrity under sustained weather cycles and standing water conditions. The polymer formulation prevents degradation from UV radiation over extended service periods. No internal moving parts or mechanical seals are present to wear under load.

Replaces damaged or missing drain domes

This unit fits existing 11-1/8 in drain bodies where the original cover has cracked or been lost. The upgrade is justified when the current dome no longer excludes leaves, gravel or construction debris. It is not suited for drains with smaller or larger nominal diameters. Buyers needing a different drain size or a metal grate alternative will not find a match here.
