I recently purchased a plastic locknut for my industrial and scientific CONTROL cables. Through trial and error I found that this adjustable locknut was the perfect solution for my power transmission needs. The waterproof feature is a game-changer, and the durability of the product is top-notch .The installation process was quick and easy, and the product has been working efficiently without any issues. The only downside is that it might be slightly more expensive than other plastic locknuts in the market. Overall, I highly recommend this product for anyone looking for a reliable power transmission accessory..
