Ever find that you’re trying to screw a light into a light fixture and the socket is just too deep into the fixture?
This socket extender is what you’ve been looking for. One extender adds 3 cm. (1.2 inches) to the total length.
Just screw one onto your light and screw it into the socket. Still not enough? Screw on another extender until your light can reach down into the depths of your fixture.
