FAQs
Can this cable seal be installed below the waterline?
What's the best way to drill a blank bung?
Before drilling holes, freeze the blank seal in a freezer, this makes it very easy to accurately and neatly drill the hole. For best fit around cables drill a hole Ø1-2mm larger than the cable diameter. When drilling into a frozen blank seal this hole will look far too big but when the seal defrosts, it will be a good tight fit.
