STANDARD EXTENSION
VALVE BOX
Designed to work with our Standard Valve Box for mainline or other deeper burial projects. Can also be used
alone for shallow burial systems. Engineered to house up to four valves with durable truss design to provide
maximum strength.
• T-Top Locking Lid—Makes it quicker to take the lid on and off resulting in faster service times.
• 100% Recyclable—Some models contain pre and post-consumer recycled materials.
FEATURES AND BENEFITS
• T-Top Lid—Extends all the way to the edges of the base, preventing grass and dirt from interfering with
the lid to base interface. The solid lid surface with indented finger holes ensures that no water, dirt or sand
intrudes through the lid into the valve box.
• Lid Traction Bars—Incorporates textured surface in lid to provide traction and safety.
• Reinforcing Ribs—Utilizes a unique truss design on the underside of the lid to provide maximum support.
• HDPE Structural Foam Process—Derives from a combination of high-density polyethylene material and a
proven manufacturing process which ensures maximum strength and durability.
• UV Stabilizers—Incorporates special UV inhibitors to minimize long-term effect of sunlight.
• Rigid Skirt—Extends around the full perimeter of the valve box providing maximum top load, side load and
torsional rigidity.
• Multiple Color Options—Available in green, green on black, and tan, allowing you to match the box lid to
the landscape for optimum aesthetic effect.
