Review on Uxcell Waterproof Adjustable Locknut 13Mm 18Mm Industrial Electrical and Wiring & Connecting by Dhoal Shankar

I would be VERY tired of ordering these. They are not resistant to UV radiation and become brittle after brief exposure to the sun. They are therefore not suitable as cable ducts for access to the roof or anywhere else outdoors. Unfortunately, if they were better designed, they would be very comfortable.
