The Zurn Z899-100 trench drain system is designed specifically for elevator thresholds and other shallow-deck applications where rapid water evacuation is critical. Crafted from Type 304 stainless steel, this drain is engineered to handle a flow rate of 100 gallons per minute (GPM) and meets stringent building and fire-safety codes. The channel is shallow to suit post-tension concrete slabs and includes heavy-duty grating options rated for high load conditions.

Key Features

• Fabricated channel in Type 304 stainless steel (#11 gauge) with bead-blasted finish for durability and corrosion-resistance.

• Designed to evacuate up to 100 GPM to prevent water accumulation at elevator openings and maintain safe access.

• Shallow body depth suitable for limited-depth installation areas (ideal for thin slabs or post-tension floors).

• ADA- and heel-proof grate options: stainless steel wire grate (-SWG) and fabricated slotted grate (-FS), both lock-down and load-rated to 2,500 lbs.

• Complies with fire-safety and building code requirements, including San Francisco Fire Code (Section 511.1) and accessible design guidelines.

Note: Zurn trench drain products are subject to a $750 minimum order.
