10 Pcs White Plastic Waterproof Cable Glands M20 x 1.5

I looked a long time and finally found this product. The threads will screw into a standard 1/2 inch wall cluster(see picture). I had ordered other similar items but the threads were just not quite right. This one fit perfectly into a wall cluster from my local HD. The body is plastic with a rubber gasket interior. Used firm force to tighten and showed no sign of marring or stress. The gasket forms a watertight seal around the Pigtail for my LE® 100W Super Bright Outdoor LED Flood Lights, 250W HPS Bulb Equivalent, 10150lm, Daylight White, 6000K, Security Lights, Floodlight, 5 Years WarrentyHope this helps with your purchase.
