Ensure your SR MAG BRX48 broom keeps sweeping clean and strong with the BOSS 143‑3685 Full Bristle Kit. A complete, OEM‑grade replacement kit built to restore full brushing power, this kit ensures optimal contact with surfaces, consistent performance, and longer broom life. Whether you’re clearing snow, debris, or salt residue, worn bristles can degrade performance; this full kit restores your broom’s factory standard sweep.
Key Features & Benefits
-
Full OEM Bristle Replacement: This is the complete bristle kit (part number 143‑3685) engineered specifically for the BRX48 broom attachment of the SR MAG series. Using genuine BOSS bristles ensures correct fit, optimal length, and durable performance.
-
High‑Quality Material for Longevity: Designed to resist wear from pavement, ice, snow, salt, and road grit. Durable bristle material helps avoid rapid breakdown and keeps your broom operating longer between replacements.
-
Restores Sweeping Efficiency: Worn or splayed bristles can reduce sweeping coverage, increase work time, and leave behind debris. Installing this full bristle kit restores even contact across the surface for cleaner passes and better job results.
-
Cost‑Effective Over Time: Replacing just the bristles rather than more expensive components (like the whole broom frame or motor) helps lower long‑term maintenance costs. Investing in a proper bristle kit extends the useful life of the rest of your broom components.
Why You Should Replace
Over time, the bristles on your BRX48 wear down, bend, splay out, or get damaged. When that happens:
-
Sweeping becomes uneven
-
More passes required to clean surfaces
-
Increased stress on frame, caster wheels, and mounts
-
Poorer visibility / finish quality
Using the BOSS 143‑3685 Full Bristle Kit brings your broom back to its intended design form—ensuring full contact, more efficient sweeps, safer operation, and longer life for adjoining components.
