Product Overview
The Waterway 519-9557 Wide Mouth Mounting Plate serves as a critical component in maintaining the integrity and performance of inground pool skimmer systems. Over time, exposure to chemicals, sun, and water pressure can cause mounting plates to warp, crack, or lose their ability to hold a secure seal. Replacing a worn plate with this OEM component restores the skimmer’s ability to maintain suction, prevents leaks, and ensures a stable connection between the pool wall and skimmer assembly.

Constructed from rigid, chemical-resistant plastic, the 519-9557 withstands long-term immersion and pressure while maintaining its shape and strength. The pre-drilled mounting holes make installation straightforward and precise, aligning perfectly with the skimmer body and faceplate for a proper gasket seal.

This mounting plate is a must-have for pool technicians and homeowners servicing or upgrading wide mouth skimmers on inground pools. It ensures that your skimmer performs as intended — securely fastened, properly sealed, and ready to handle daily circulation demands.
