The Polyvance Compression Roller, No. 6144, is designed to reduce the finishing time and enhance the strength of plastic welds by smoothing and compressing the joint between the plastic filler rod and the base material. It can also be used to improve the appearance of back-side welds and accelerate the process of embedding reinforcing mesh into a repair. The tool features a polished stainless-steel roller and smooth sealed cartridge bearings, an ergonomic handle, and a high-strength plated steel frame. Additionally, the Compression Roller acts like a heat sink to cool the weld.
