Addressing the cosmetic concerns consumers have over unsightly cabling, the global manufacturer Legrand has introduced its WP-9000 Power Supply In-Wall Extension Kit. 

Legrand says its extension kit is a code-compliant solution that provides electronics installers an option to hide cabling runs that homeowners find unsightly. It can be used to power low-voltage devices such as touchscreens, soundbars, IP cameras, LED lighting, in-wall amplifiers and other components

Legrand says the kit can be used for nearly any type of low-voltage product where aesthetics and power are concerned.

The kit's keystone adapter connects to power supplies rated up to 48-volts DC at 100 watts. At receptacle height the extension kit extends power in the wall via speaker cable to wall mounted low-voltage devices whereever applicable. 

Legrand says the WP-9000 kit only needs a wall plate and whatever length of cable necessary to complete the connection. The kit comes with a keystone adapter insert, four crimp connections, and a four-inch barrel connector cable assembly. 

Legrand adds that, through its universal design, it supports connections to nearly any type of power supply. 

The WP-9000 Power Supply Extension Kit from Legrand is available for $16.
