OPW 1C-2100-DEVR Threaded, Five-Gallon, Fill/Spill Containment Manhole Duratuff II Base with Cast Iron Cover and Drain Valve

• Easy Installation – Reduces job-site time and installation costs. OPW Thread-On Spill Containers screw directly onto 4" NPT riser. No external connections to make; adjust the final grade height and support the unit with backfill. 
• Integral Pull-to-Open Drain Valve – Allows high-speed drainage of excess product into the tank. Designed with a convenient self-cleaning seal and removable screen for easier component cleaning. 
• Rain-Shedding Cover – Available in either cast aluminum or cast iron, this unique design incorporates a seal in the underside of the cover. The seal seats between two dams on the mounting ring to prevent surface water from entering the spill container. 
• Fuel Compatibility – Designed to accommodate the fuels of the future, including methanol, ethanol and fuels with MTBE additives. 
• Product Identification Tags – Available for both the cover and bucket to positively identify the product contained in the UST with standard API symbols.  
• Heavy-Duty Mounting Ring – The angled ramp design offers superior protection against snow plow and traffic damage, and provides for secure concrete anchoring. 
• Corrugated Bellows – can be adjusted +/- 1 inch for desired grade level. 
• Duratuff II or Cast Iron Base – Composite Duratuff II material is lightweight, durable, and conductive. A rugged optional cast iron base is also available.
