Cutting Edge Poly 48" x 5" x 1" UHMW Poly Cutting Edge Compatible with BOSS Snowrator 4-Foot Plow, Replaces STB13773, Reversible 5-Hole Design

Upgrade your BOSS Snowrator with a cutting edge engineered to outperform the standard factory edge. Manufactured by Cutting Edge Poly from solid, industrial-grade UHMW polyethylene, this heavy-duty edge measures 48 inches long, 5 inches high and a full 1 inch thick—providing exceptional strength, wear resistance and dependable commercial performance.
Unlike steel edges, UHMW poly will not rust, corrode or leave rust stains. Its low-friction surface glides smoothly across pavement while helping reduce chatter, vibration, noise and operator fatigue. It delivers a clean scrape while being gentler on concrete, asphalt, pavers and other finished surfaces.
The precision-machined five-hole mounting pattern is designed for direct compatibility with the 4-foot BOSS Snowrator plow and replaces BOSS part number STB13773. Its reversible design allows the edge to be flipped when one side becomes worn, extending its usable service life and delivering greater value.
Cutting Edge Poly edges are built from premium, commercial-grade material—not thin, lightweight plastic. Every edge is CNC-machined for consistent dimensions, proper hole placement and dependable fit. The result is a rugged aftermarket upgrade designed for snow professionals who want smoother operation, longer-lasting performance and better surface protection.
Includes one black UHMW poly cutting edge. Verify your blade dimensions and five-hole mounting pattern before ordering. Proudly manufactured in the USA by Cutting Edge Poly.
