Rack-a-tiers 42740 Hole Cutter Mud Ring

Product Description

The RACK-A-TIERS 42740 is a hole cutter mud ring designed to work with compatible hole saw systems used in electrical rough-in and finish work. A mud ring serves as a guide and depth stop when cutting holes through drywall, plaster, or similar finish surfaces, helping keep cuts clean and consistent. This accessory is suited for electricians working on device box openings, outlet placements, and fixture cutouts where a flush, precise hole is required. It pairs with the corresponding Rack-A-Tiers hole cutter to complete the cutting assembly.

The 42740 mud ring is used in residential and light commercial electrical installations. It is most commonly deployed during rough-in or trim-out phases when cutting drywall openings for electrical devices and fixtures. Electricians and low-voltage installers working with Rack-A-Tiers hole cutting tools will find this accessory keeps the cutter properly registered to the wall surface, reducing tearout and improving hole consistency across repeated cuts on a jobsite.
