Jumbo Valve Box Extension (Green)

Commercial grade irrigation valve boxes, turf irrigation valve boxes, and utility underground enclosures that will meet your specific needs

Lightweight - Easy to use while providing higher load and environment resistance qualities over current products in plastic or concrete.

Reduced Side Angle - Provides easier readjustments to grade, while inside area remains the same.

Increased Break Resistant - Structural foamed plastic parts have a lower density than straight injection products, allowing a part to still provide high flexibility through proper design while remaining resistant to impact and bowing when installed.

Non-Conductive or Sparking - Ideal for use in electrical or phone connection junction boxes.

UV Protection - UV inhibitors to prevent cracking and discoloration for a long lasting product.
