The Rain Bird VBJMBB Jumbo Valve Box (body only) is a large-capacity underground enclosure designed for irrigation valves, manifolds and controls. Its roomy interior and service-friendly features make installation and maintenance faster while protecting components from dirt and damage.

  • Spacious interior: Room for multiple valves, manifolds and large fittings — ideal for commercial or robust residential systems.
  • Quick pipe placement: Pre-scored knock-outs allow fast pipe entry without cutting; knock-outs slide back into place to seal around pipe after backfill.
  • Engineered strength: Constructed to maintain horizontal and vertical integrity under load, even with knock-outs removed.
  • Pest and service features: Bolt-hole knock-out helps deter critters when the locking bolt isn't used; side shovel slot gives easy lid access during service.
  • Dimensions: Overall length 26.3" × width 19.8" × height 12.1" for a deep, wide profile that accommodates larger valve assemblies.
  • Body only: This listing includes the body only; lid and certain accessories are sold separately and match VB Series components.

Designed for installers who need a durable, serviceable enclosure, the VBJMBB reduces installation time and simplifies long-term servicing. See the VB Series brochure in product documents for technical drawings and accessory compatibility.
