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.
