External junction boxes

Quite like these,for various connections,hate the connectors inside though.
Wondering would you use compression glands on entry for flexes or pierce through the sealing membrane../neoprene to seal/hold the cable.

the Swa gland thread does not reach the inside of the box

You must be doing something wrong then. Are you, maybe, using internal rather than external glands

External glands,the boxes are threaded,& screwing the gland to the box,theres no way a locknut will fit into it.
Banjos are external.

External banjos on this boxes look awful. Use the correct parts here is one fitted.

Earthing nuts do not fit them you are supposed to use these neater than lashing a banjo on the outside.

This is the correct item you use for those types of boxes as the thread is not long enough to bite the Parana earthnut. Wiska is a manufacturer they also do a smoothed faced adaptable box that you drill and the wall thickness is such that you can fit an earthnut around the gland thread.

Always use glands with them and either strip connectors or wagos depending on how many I've to terminate inside.
Never use the connectors inside, although the brass part can be used as a nut for some outside lights if you drop and lose it lol just touch up with a black marker.

Use them all time. The earth bars are great. Always compression glands, the cost is negligible & way better job.

use flex glands every time. screwing the gland in breaks the neoprene seal, without you needing to cut it away first. with SWA, you can use banjos on the outside.

The banjo needs to be attached to the gland by a locknut of doing this, trapping it between the gland and the plastic is not good as the plastic will flex with time and cause it to become loose.
