I'm looking for an explosion-proof stainless steel electrical cable gland, specifically in size M20. We are interested in placing an order for 100 units. It is essential that these cable glands meet high safety standards for use in hazardous environments. Please provide specifications, pricing, and lead time for the order. If you have different sizes or options available, feel free to include those as well. We're aiming for quality products, so any certification or testing information would also be appreciated. Looking forward to your prompt response!
