The CGW 49533 back-up pad is designed for use with hook and loop abrasive discs on 4-1/2 inch diameter sanding tools. It features an internal 5/8-11 threaded arbor to fit compatible machines and a foam layer that provides medium stiffness and enhanced grip for hook and loop discs, helping to maintain consistent contact during grinding or finishing tasks. The pad’s construction is tailored to balance firmness and conformity, which supports stable sanding pressure and help reduce loading of the abrasive surface.
With a 4-1/2 inch diameter and a 1/4 inch foam thickness, this back-up pad prioritizes consistent heat dissipation and even abrasive engagement. The foam helps cushion during use while preserving the abrasive disc’s alignment, which can contribute to smoother finishes and more predictable material removal. This pad is packaged as a single unit, ready for use with 5/8-11 arbor-compatible tools and standard hook and loop discs that match the pad size and interface.
When selecting backing components, verify that your abrasive discs are compatible with a 4-1/2 inch pad and that the disc’s center hole and hook-and-loop interface align with the pad’s dimensions. The 5/8-11 arbor size and the foam’s mid-stiffness rating are intended to optimize disc grip and contact stability for routine surface finishing and material removal tasks on appropriate substrates.
