The TUNDRA SPECIALTIES *11503 (321392) is a flanged plastic basket strainer designed to capture debris and protect downstream components in fluid-handling systems. Built with a plastic construction and a flanged mounting design, this strainer seats securely in compatible sumps, tanks, or basins. The 8.5-inch square basket footprint provides solid debris-holding capacity, reducing service intervals in applications where particulate load is a concern. Licensed plumbers and mechanical contractors are the typical installers for this type of strainer in commercial and industrial settings.
This flanged basket strainer is suited for use in pool and spa systems, commercial plumbing sumps, process water lines, and similar fluid-handling installations where a removable basket element is required for routine cleaning. The flanged design allows for secure, stable mounting to mating flanged sumps or drain bodies. The plastic basket construction resists corrosion in wet environments and keeps weight low for easier service access.
Designed as an OEM-style replacement flanged basket strainer for use in commercial plumbing, pool, spa, and process water applications requiring an 8.5-inch square flanged basket configuration.
Installation should be performed by a licensed plumber or qualified mechanical contractor in accordance with applicable local plumbing codes. Shut off and depressurize the associated system before removing or installing the basket strainer. Verify flange bolt pattern and basket dimensions match the receiving sump or drain body before installation. Do not overtighten flange hardware on plastic components, as this may cause cracking or deformation.
