Legrand Wiremold CMK70 In Wall TV Power Grommet Kit - Clean Cable

In this review of the Legrand Wiremold CMK70 in wall TV power grommet kit, the bottom line is simple: it is a practical solution for anyone who wants to hide TV cables without running new wiring or hiring an electrician. The kit includes everything needed to create a clean in-wall cable path, from two grommets and a pre-wired harness to a hole saw and fish tape, and installation is truly plug-and-play. For homeowners mounting a flat screen and aiming for a professional appearance, this kit delivers fast results and a much neater setup.

Key Features

• Complete kit: Includes two power grommets, a pre-wired wire harness and accessories so users have all parts needed for a single TV installation.
• In-wall power outlet: The assembled kit provides two outlets that accept most TV plugs, keeping the TV power connection concealed behind the wall for a cleaner look.
• HDMI cable pass-through: The brush-style AV pass-through lets HDMI and other low-voltage cables run behind the wall without damaging cables or connectors.
• Tools included: A hole saw, handle and fish tape are part of the package so the install can be completed without separate tool purchases.
• Easy installation: Pre-wired harness and plug-and-play design mean no electrical termination or electrician is required, typically installable within 30 minutes.

Who It's For

The CMK70 is ideal for homeowners or installers mounting flat screen LED, LCD or plasma TVs who want a tidy, professional appearance without hard wiring. It works well for living rooms, bedrooms and offices where the wall construction matches the kit requirements.

It is not intended for users who need full in-wall hard wiring or for walls that do not meet the minimum stud and drywall thickness requirements. Those needing permanent hard-wired power should consult an electrician or consider a different in-wall power solution.
