The Detention Area Drain is a robust, finish-floor drain based on the Zurn Z315, engineered for demanding environments where secure, reliable water removal and long-term floor integrity are essential. Its Dura-Coated cast iron body and anchor-flange design ensure strength and stability under heavy use, while the adjustable nickel bronze top lets you achieve a flush, clean finish with tile, terrazzo, or other flooring surfaces. An invertible membrane clamp and built-in weep/relief paths make the drain compatible with waterproofing systems, and the secured strainer with optional locking cover helps prevent unauthorized access, debris entry, or tampering — ideal for detention areas, secure facilities, or institutional floors with strict maintenance and safety standards.
