The green male Gilbert replacement plugs are the perfect complement to commercial Christmas lighting or architectural designs. This heavy-duty SPT-2 plug is capable of handling up to 10 amps and 125 volts and is UL listed for indoor/outdoor use. The simple slide back cover allows prongs within the cap to make contact easily and safely to stringer wire or existing lighting sets. You will never need to bunch the extra cord of your lighting set again. Just attach a plug where you need it!
