This flap is specific to the Dolphin M4/M400 series (pre-2015 residential cleaners). Proteus models (DX4, DX5, etc.) use a different chassis design and flap assembly with their own part numbers (typically in the 99997xxx range).
Check your Proteus model number against the Maytronics parts diagram or send us a photo, we'll identify the exact OEM flap you need. order.support@eztestpools.com / 877-209-7773
