And as I said they are not there as a complete replacement for glands:Sure - in that situation (with the entirety of the glands within the enclosure' {trunking}), the alternative approach might well take up a bit less space.
However, I was obviously talking about the 'normal' situation in which ~95% of the gland is outside of the enclosure, in which case it's fairly obvious which requires the least space within the enclosure.
Kind Regards, John
in fact I'll go back a few years and say brass glands were never intended to be to be the replacement for the style I've now shown, as they preceeded glands by a lot of years.I'm not trying to say these are suitable for pics in: (Edit Rockys 'other peoples work thread) in fact just the opposite.
