Rapid Deployment for Supply Line Operations Engineered to speed up critical water supply connections, the R&B Fabrications Large Diameter Hose (LDH) Strap is a heavy-duty tether designed to anchor your 4” or 5” supply line to the hydrant while the engine proceeds to the fire. Built from massive 3-inch wide nylon webbing with a tensile strength of over 22,000 lbs, this strap withstands the extreme drag forces of paying out heavy hose at speed.

Key Features

  • Extreme Tensile Strength: Constructed from 3-inch wide industrial nylon webbing rated at 22,550 lbs, ensuring the strap never snaps under the weight of dragging LDH.
  • Hydrant Anchor Point: Allows the firefighter to pull a fold of hose from the bed, loop it over the hydrant, and secure it instantly, signaling the driver to "GO."
  • Quick-Release Attachment: Features a webbing loop that secures to the engine’s rear grab bar, keeping the strap accessible until the moment of deployment.
  • Secure Hose Retention: Uses a heavy-duty zinc-plated adjuster and a robust hook-and-loop (Velcro®) closure to bind the hose fold tightly, preventing premature deployment.
  • Glove-Friendly Operation: Equipped with an oversized pull tab that allows firefighters to rip the Velcro open and release the hose easily while wearing thick structural gloves.
  • Hydrant Tool Integration: Designed to work seamlessly with the R&B #441 Oversized Hydrant Tool Kit or #443 Tool Bag, keeping wrenches and mallets attached to the supply line.

Why It Matters The "hydrant man" has one of the most pressure-filled jobs on the fireground: catch the hydrant, anchor the line, and wave the engine on—all in seconds. If the hose slips or the strap breaks, the operation stalls. This LDH strap provides a fail-safe mechanical link between the hose and the hydrant, ensuring a smooth lay-out every time.

How to UseSetup: Attach the strap to the tailboard grab bar. Loop the strap around the first coupling/fold of your LDH supply line in the hose bed. Secure with the Velcro closure.Deployment: At the hydrant, grab the strap (and attached hose fold). Loop the strap over the hydrant barrel. Signal the driver. As the engine drives away, the hose pays out from the strap's anchor point.Connection: Use the quick-release tab to free the coupling and connect to the hydrant.

Technical Overview The strap measures 60 inches in length, providing enough slack to wrap around large barrel hydrants. The use of heavy brass rivets and reinforced stitching at stress points ensures longevity in harsh weather conditions.

Frequently Asked Questions

Why does the R&B Large Diameter Hose Strap use 3" nylon webbing with 22,550 lbs tensile strength?

The LDH-01YL is engineered for extreme fireground conditions where standard straps would fail. The 3" nylon webbing with 22,550 lbs tensile strength ensures the strap can handle the weight and stress of fully charged large diameter hose (LDH) during rapid deployment at hydrant operations. This heavy-duty construction, combined with reinforced stitching and brass rivets, prevents strap failure when firefighters pull hose from the rig under time-critical conditions, allowing the engine to proceed immediately to fire suppression while maintaining a secure hydrant connection.

How does the R&B LDHS work with the #441YL Oversized Hydrant Tool Kit for complete hydrant operations?

The Large Diameter Hose Strap (SKU LDH-01YL) is designed as part of R&B Fabrications' integrated hydrant operation system. While the LDHS secures to the engine's top grab bar and allows firefighters to deploy LDH over the hydrant using the hook & loop closure system, the #441YL Oversized Hydrant Tool Kit or #443 Tool Bag provides the wrenches and adapters needed to complete the connection. This coordinated approach ensures firefighters have both the hose deployment solution and the tools to establish water supply in one streamlined workflow.

Can firefighters operate the R&B Large Diameter Hose Strap pull tab while wearing structural firefighting gloves?

Yes, the LDH-01YL features a glove-friendly pull tab specifically designed for operation while wearing thick structural firefighting gloves. This design consideration is critical during fireground operations where removing gloves wastes precious seconds and exposes firefighters to hazards. The zinc-plated adjuster and heavy hook & loop closure are also sized for gloved operation, ensuring the entire 60" strap system can be deployed, adjusted, and secured without compromising firefighter safety or efficiency.

What makes the R&B LDHS different from standard hose straps for engine company operations?

Unlike generic hose straps, the R&B Large Diameter Hose Strap (MPN: LDH-01-YL) is purpose-built for large diameter hose deployment at hydrants. Standard straps lack the 22,550 lbs tensile strength needed for LDH, don't include the quick-release attachment system for engine grab bars, and aren't optimized for the hook & loop closure method that keeps spare hose secured during hydrant operations. At 32 oz and 60" length, the LDHS provides the reach and durability fire departments need for reliable hydrant connections, while the high-visibility yellow color ensures visibility during low-light operations.

Will the R&B Large Diameter Hose Strap fit on apparatus with non-standard grab bar configurations?

The LDH-01YL's 60" length and adjustable zinc-plated adjuster system accommodate most engine company grab bar configurations. The webbing strap secures to the top grab bar regardless of spacing or mounting style, and the hook & loop closure allows firefighters to customize the fit for their specific apparatus layout. However, departments with unique custom rigs should verify the 60" length provides adequate reach from their grab bar to the hose bed. R&B Fabrications' heavy-duty construction ensures the strap maintains secure attachment even on apparatus with wider-than-standard configurations.
