I recently bought a protective cap for my machinery from this Industrial & Scientific company and I am very pleased with it.As a result of using this product, I found that it is very durable and can withstand heavy use. The cap is easy to install which is great for anyone who needs a quick fix. The only downside I could see is that it's a little expensive compared to other protective caps in the market but with the amount of protection it provides, I think it's worth the investment..
