Swimline 8939 Thru-Wall Skimmer Flap Weir
Best replacement part for pool owners restoring their skimmer's efficiency.
This simple flap is the unsung hero of a clean pool, acting as the critical gatekeeper that forces surface water—and debris—directly into your filter. It’s a minor, inexpensive fix that saves you from manually scooping the surface, though you’ll need to double-check your specific skimmer dimensions before ordering.
