Piranha Nut in MK Masterseal Box

[taycast]

Does anyone know if a 20 mm piranha nut can be fitted inside a MK masterseal 2 gang socket? I have found with some other weatherproof boxes, there is sometimes not enough room to fit/tighten these nuts due to the inner shape and profile of the box. Thanks

I have had the trouble of which you speak.

While having not used a Piranha before, I get round the problem of fitting SWA locknuts into such boxes by lying the nut in the box and attaching the gland BEFORE fitting the SWA to the assembly.

Don't turn the piranha nut, let it dig into the backbox.
You should be turning the gland to lock against the piranha nut then terminating your SWA and tightening the backnut.

It doesn't need to be super-tight, remember, as the nut has a little grub screw which tightens against the gland and stops it coming loose.

Masterseal enclosures are pretty spacious inside, and free from ribs etc. Now, if you said you were using a Wiska.....

Now, if you said you were using a Wiska.....

Agreed - WISKA are especially hopeless for terminating SWA IMO. It should be ideal, with the 20mm thread, but there's no way to connect the armour using banjo or Piranah.

Edit: Stupid me. I just found this handy WISKA accessory http://www.tlc-direct.co.uk/Products/WKEC308.html

Heres a mock up in a single masterseal and spins 360 degree easy enough.
A twin is the the same depth I would expect.

Good of you to take the time to show the pictures - thanks - looks like there is plenty of space as you show. Being a true Scotsman, I didn't want to shell out for a Masterseal if my nuts weren't going to fit.

Fnarr, fnarr.


And will you look at Rocky - he's so posh he's got a lace tablecloth on his workbench....

 

[securespark]

Not so posh..Look at that carpet....

Only kidding Rocky!!

My local neweys have never heard of them, but their bringing them in as a stock item for me in 20 and 25mm sizes. JOY

Rocky, have you got the piranha nut on the wrong way?
Shouldn't the serrated edges not be there to bite (piranha!) into the backbox which causes the locknut to hold in place?

I know it's only a mock-up before you say!

IIRC you are supposed to put shiny side down (as in the picture) with plastic enclosures, and toothed side down in metallic enclosures.

Just curious rocky, how good an earth do you get off a nylon compression gland

There's no mention of plastic or metal enclosures.
