Hi all, Off in a bit to a xmas meal and several beers so time for a quickie. What does the "S" stand for with these glands. Is it something simple like "small" as they are only used for up to 4mm 3 core SWA. How do internal glands BW differ from external CW glands. Do the external glands have extra seals in? And if you bright "sparks" could tell me what BW and CW actually stands for then you are awarded a "Brucie Bonus". Many thanks and have a good night.
