When you need rugged durability and perfect alignment for your BOSS SR MAG straight blade attachment, the BOSS 143‑3550‑03 SR MAG Straight Blade Push Frame delivers.

Key Features & Benefits
-
OEM Quality Fit & Compatibility: Designed specifically for the SR MAG line, the 143‑3550‑03 push frame integrates seamlessly with straight blade attachments, preserving factory tolerances and performance.
-
Robust Construction: Built from heavy‑duty materials capable of handling the stresses of plowing. This push frame helps resist bending, fatigue, and impacts from packed snow or hidden obstacles.
-
Reliable Blade Support: The push frame is the structural backbone that transfers the blade’s load to the SR MAG. A solid frame ensures that the blade aligns correctly, angles properly, and responds accurately to hydraulic or manual controls.
-
Reduces Wear & Maintenance: With the right frame in place, less stress is placed on brackets, pins, welds, and hydraulic components – helping extend the lifespan of the entire straight blade assembly.
Without a sound push frame, blade alignment becomes unreliable, which can lead to uneven snow clearing, blade wobble, excessive stress on pivot points, and accelerated wear of both blade and mount components. Replacing worn or damaged push frame assemblies with the authentic BOSS 143‑3550‑03 Push Frame restores rigidity, enhances control, and ensures your SR MAG straight blade performs as intended.
