Elevator Threshold Drain

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. 

Elevator Threshold Drain
Keeps the Path Clear

Keeps the Path Clear

One-piece, heel-proof grating keeps people moving. A 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 can be easily removed for low-maintenance cleaning. So whether emergency personnel access is needed or it's a fast-paced day, you'll know every step will be made in a safe environment.


Total Compliance

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.
