Maximum Capacity for LDH Hydrant Operations The R&B Fabrications Extra Large Hydrant Tool Bag (Model 439YL) is the largest hose-mounted carrier in the R&B lineup, specifically engineered for modern Large Diameter Hose (LDH) operations. While standard bags fit keys and gate valves, this extended 27-inch bag is designed to hold the massive 5-inch Storz adapters, Humat valves, and heavy-duty spanners required for high-flow water supply. Key Features Extended 27” Length: Provides 1,458 cubic inches of storage, offering enough room for a 5-inch coupler or Storz adapter along with standard hydrant tools. Hose-Mounted Security: Features two heavy-duty Velcro® webbing straps that wrap securely around the supply hose (up to 5" diameter), ensuring the tools travel with the coupling when the line is laid. Impervious Durability: Constructed from 22 oz. vinyl-coated nylon, which is significantly heavier than the standard model's 14 oz. fabric, offering superior resistance to abrasion, oil, and road grime. High-Visibility Safety: Bright yellow vinyl paired with a red reflective strip ensures the bag—and the hydrant connection—are visible to oncoming traffic in low-light conditions. Why It Matters Standard hydrant bags often fail to accommodate the bulky adapters needed for 5-inch LDH connections. This forces firefighters to carry adapters separately or risk them falling out. The Model 439YL solves this by providing a "garage" for your largest water supply appliances directly on the hose, guaranteeing a complete hookup kit at the plug every time. How to Use Attach: Strap the bag to the hydrant end of your 4" or 5" supply line using the dual Velcro loops. Load: Insert the 5" Storz adapter, heavy hydrant wrench, and mallet into the main compartment. Secure: Press the full-length Velcro flap shut to retain the heavy tools during the layout. Deploy: Drag the hose to the hydrant; the bag stays attached and ready for instant access. Technical Overview Weighing 18 oz (approx. 1.1 lbs), this bag measures 27” L x 9” W x 6” H. It is designed to be the ultimate "set and forget" tool carrier for engines running LDH supply lines. Compliance & Origin Made in the USA. - Berry Compliant
