[PSUBS-MAILIST] Windows

[James Frankland]

Blue Globe seem to make all sorts of cable glands, including ones for multi
cables.  I did try and get some but the local supplier in the UK wasnt
interested once i said i only wanted a few.  The catalogues are huge, but i
think there are some multi glands in the one called, "novelties".  !
