Use this white TayMac cover when an outdoor receptacle must remain protected while a plug is connected and the installation calls for a clean white exterior finish. For Canadian outdoor electrical work, the cover, device, box and gasket should all be selected for the installation location and weather exposure.

Application Why ML500WCN Fits
Outdoor GFCI outlets Protects the outlet while plugged in and supports common GFCI device layouts.
White siding and exterior trim White base blends better with light exterior surfaces than gray or bronze covers.
Patio and deck power Expandable depth helps protect connected cords for outdoor living spaces.
Holiday and landscape lighting Useful where outdoor cords remain connected for seasonal or landscape lighting loads.
Timer-controlled outdoor circuits Pairs well with Intermatic timers, photocontrols and outdoor lighting control setups.
