Cables To Go 39871 HDMI 3.5mm gender changer

HDMI and 3.5 mm wall plate

The Cables To Go 39871 is a single-gang wall plate that passes HDMI audio and video signals alongside stereo audio through brushed aluminium. It suits installers and AV integrators who need a tidy, permanent connection point in classrooms, meeting rooms or home theatres. Flexible pigtails on both connectors simplify routing inside a standard junction box. Aluminium construction resists wear in high-traffic commercial environments.

Check your wall box and cable run

Verify that the mounting location accepts a standard single-gang wall box before ordering. Ensure the in-wall HDMI and 3.5 mm cables have enough slack to reach the plate’s short pigtails without sharp bends. Confirm that the source and display devices use HDMI female ports and 3.5 mm stereo jacks so the gender-changer layout matches your patch leads. The plate does not convert signal types or amplify the link.

Thermals noise and power

This passive adapter draws no power and generates no heat or noise during operation. The aluminium faceplate acts only as a durable mechanical housing. Normal use adds no thermal load to the cavity and requires no ventilation beyond what the wall box already provides. Long cable runs on either side determine signal quality, not the plate itself.
