OMG VTBSTR10-YW Vortex Breaker Strainer Dome

VTBSTR10-YW is the yellow vortex breaker strainer dome by OMG, designed to retrofit onto existing Hercules or Aluminum Classic roof drains in 3-, 4-, 5-, or 6-inch sizes. The strainer integrates vortex breaker technology in its cast aluminum dome to accelerate drainage (up to 2.5× more flow versus standard strainers), reduce “chugging” of water, and enhance performance under heavy rainfall. Its bright safety yellow finish helps visibility on the roof and marks drain locations clearly.
