Parts Desk Insights
Best Use Case: Use this AC Plug Holder+ to create a protected, easy-access spot for your battery charger’s 120V AC connection—so you can plug in from the dock without leaving the cord connection exposed.
Common Issues: For the cleanest install, confirm the mounting location provides solid backing for the screws and that the cover seals properly when closed. Also double-check that the plug clamp insert sits correctly before final tightening so the plug stays secure in the housing.
