Hilitchi's cable gland is a reliable, well-made product. The pack of 30 comes in 5 different sizes, ranging from very small for 0.31" diameter cables to the largest sizes of 0.72". In addition, the device is waterproof, has a waterproof ring and a rubber seal on the sealing nut. In my case, however, waterproofing was not required, so I did not test this feature. But judging by the design I would assume it will work as intended. Since I have a white cable, I ordered a white one, but the manufacturer offers a similar product in black. In addition, it is well packaged, each size comes in a separate zippered storage bag. So if your project requires you to route cables from the outside world into the enclosure, this cable gland is the best and highly recommended.
