Elevator/Threshold Drain

Only Patented System in the Industry

We prove our dedication to quality control with the Z899 system's design patent. After surveying real professionals and solving for the average jobsite, our systems offer the ideal balance of lightweight design and durability. We made sure contractors could handle our trench drains without heavy lifting, alignment hardware, or extra hands.

Keeps the Path clear

One piece, heel-proof grating keeps people moving. 100 gpm flow rate prevents water from cascading, whether the drain is installed in front of an elevator or entryway. 

The system consistently drains for a slip-free path, and easily removes for low-maintenance cleaning. So whether it's emergency personnel access or a day that's just fast paced, you know every step was made to ensure safety. 

Total Compliance

Performance is nothing without compliance. We created our system to adhere to all regulations and adapt to emerging codes. 

Our drain complies with 2013 California Building Code: 403.61, 403.6.2, 3007.4, 3008.4 with 2013 San Francisco Fire Code, Section 511.1.4. The one-piece system is also ADA compliant. Expert assistance is available to verify plans, specs, and code requirements.

Flexible solutions

Whether it's discussing our product portfolio, selecting grate style, or drafting drawings for your client quote, our in-house engineers can give you the materials (and assurance) to guide you though the process. We offer a wide customizable selection to satisfy all applications, installation requirements, and building aesthetics.
