I don't use these much.

How do you get a gland screwed fully home without spending 15 minutes filing the hole open?

?

Just screw the gland in and let it push the soft centre out. You may need your long nose pliers just to finally pull the centre away.

Screw it straight in with a pair of pump pliers. The gland will take for the first turn and the rest is just brute force.......They were designed like this for quick assembly.

As above...

Use an adjustable spanner or plumbers pipe grips to wind in the gland

Some are very stiff and do take some brute force to wind in

I quite like this design as you don't need to faff about with hole cutters

I use them a lot but with SWA you can't use the banjo and have to buy Wiska's pricey earthing bar.
You've got to admire them, they create a problem and then charge you handsomely to solve it!

I've never had any problem with them.

Tried that.
Even with a lot of force it didn't want to screw in.

Is it because you don't use them?

I`ve never had a problem, perhaps you got a faulty one. Screw gland in firmly and blank pops out (mostly) just grab with round nose pliers to break it off.

The 'combi' boxes have a soft membrane closing the actual hole, and it breaks/tears out as the threaded part goes in.
These work well with the earthing bar or Pirahnas in the larger boxes.

here

But if the thing blanking the hole is hard, they are an older design, and the knock outs need actual knocking out

here
not sure what type you have. note that the fittgins they show on that page only have 2 or 3 turns of thread so dont need to go right through into the box at at full diameter.

Mike, the second picture shows glands with noticeably shorter threads, which look like they're designed to screw fully in to the shoulder without having to break the membrane to do so.

@Mike,
The second link are for internal fitting and the first link, doesn't work for me, and I suspect are the IP rated ones. I've only used the former for outside and prefer to use Gwiss for internal installs and drill my own holes.

I use whisker boxes all the time when doing outside lights on pubs, but I do find plastic stuffing glands can be a pain to screw in and pop the membrane out so i do tend to wind either a brass bush or a swa gland in first to clear the membrane, takes a few seconds longer per gland but never fails

Very occasionally I have to open the 20mm threaded hole with a metal gland if the poor quality plastic one that I am using has weak threads. Then I can just fit the new plastic gland afterwards. But with good quality plastic glands it is normally just a case of push and turn to open the sealed hole.
