Rain Bird VB-MAX-H rectangular maxi jumbo valve box - 103 x 69 x 46 cm - lockable green lid

Rain Bird VB-MAX-H maxi jumbo valve box for large irrigation systems

The Rain Bird VB-MAX-H is an extra-large rectangular valve box designed for underground installation of irrigation valves, manifold assemblies and other components of automatic irrigation systems. With a maximum bottom length of 102.5 cm, it provides generous space for extensive valve installations and complex pipe connections. Its spacious design makes it particularly suitable for large residential gardens, sports fields, landscaped areas and professional irrigation systems.

The durable black housing protects installed components from soil, dirt and mechanical impact. The lockable green lid blends naturally into lawns and landscaped areas and is secured with two stainless steel bolts. Its large top opening provides convenient access for inspection, servicing and replacement of installed irrigation valves.

Reinforced construction with secure lid locking

The Rain Bird maxi jumbo valve box features reinforced corrugated sidewalls and a wide base flange for improved structural stability. The black housing is manufactured from 100% recycled plastic and is designed for long-term underground installation.

The green lid is secured to the housing using two stainless steel bolts, washers and retaining clips. Beveled lid edges help minimize damage caused by lawn maintenance equipment. Two shovel access slots on the housing and integrated wrench grips on the lid make opening and removal easier during maintenance.

18 preformed pipe knockouts for flexible installation

The Rain Bird VB-MAX-H features 18 preformed pipe knockouts for flexible pipe routing. Six large knockouts at the ends accommodate pipes up to 127 mm in diameter, while twelve smaller knockouts along the sides are designed for pipes up to 76 mm in diameter.

The required knockouts can be removed during installation. Integrated knockout retainers allow removed sections to be repositioned above installed pipes, helping prevent soil and debris from entering the enclosure during backfilling.

Spacious design for complex irrigation manifolds

With overall maximum dimensions of 102.5 x 68.9 x 45.7 cm, the Rain Bird VB-MAX-H provides ample space for larger irrigation valves, extensive manifold assemblies and multiple pipe connections. The generous top opening allows easy access to installed components for maintenance and servicing.

The practical design makes it possible to inspect or replace valves and fittings without excavating the entire installation. Interlocking bottoms also allow two compatible valve boxes to be connected for deeper installations, making the maxi jumbo valve box a durable and maintenance-friendly solution for demanding irrigation projects.
