Smallest Enclosure Face

[Sidewinder]

sellers,

I think I get your idea, but a 20mm gland lock nut is 27mm a/f which is about 42mm across corners, thus the spacing is no where near what you suggest overall, I believe.

No banjo required BTW

A knurled lock ring has been suggested, but the OD & bearing faces are quite small, thus a reduced mechanical interface strength.

Not seen a nut as you describe on a gland, but I have on many other things done up with a hook spanner like this?:

I'm not sure that 1m is too much for 25 off 12mm diameter SWA cables coming into an enclosure TBH.

I have to terminate these into 100 points and send them back out on 2x25 pair duct grade Cat6's @ dia 15mm in stuffing glands, so this option will keep me close to the wall and give me room to work in case of re-configuration if I leave enough slack in the cores to reach either end of the enclosure.

I am allowing for some, future expansion BTW!

Wixroyd are a great company to deal with out of interest. They're just doing a special 100 off aviation style lock pin job for me. Talk to Marcus Iafrate down there.

I've been dealing with Wixroyd for over 15 years now, though I tend to where possible design around standard parts, so this job is an exception for me!

have a look at this quick paint sketch, is that how you propose them?  I don't think you could/should go any closer.

I sometimes use this method. But then substitute the locknuts for rings...I like lock rings .

I read somewhere a while ago about Niccy going all moody and deducting 1 jimmy savile point if locknuts were tw@ted up with a chisel or other percussive driven instrument...just saying

many moons ago as an apprentice I remember the NIC man pulling up my boss about the chisel marks on the locknuts,

'well, you know they are all tight then, dont you'

and he walked off .

Yes Sellers, that is how it was laid out in CAD, with a 3rd row, mirroring the two you have in the top row below the single at the same spacing, it was all calculated out from the BS size of a hex conduit lock nut, the a/f dimension converted to across corners, then allowing a few mm for my lock nut spanner to pull the glands up tight.

This was then replicated along the enclosure to give me 36 entries, with only 3 rows to keep the enclosure as tight to the wall as possible.

It does not take long to layout in CAD with arrays & TTR circles!

Apart from the dia 50mm allowance, I have not worked out many other dimensions except the overall, as I let the CAD system do this.

The Niccy men , like many others who dictate what we should be doing , have probably never struggled to get the grips in at a silly angle in the top of an enclosure.

A hospital engineer was looking at the chisel marks on a 2"  locknut , his comment was  " Well at least we know its tight" .

I look at it like this , the locknut needs to be tight .....the grips won't work properly.......what to do ?  .....  run off giggling.......leave it loose......or knock it round with a chisel .

I find these good!  :innocent

Wow, they certainly have an off the wall tool range.....including a sausage cooking aid. Are they manufacturing or just an agent?

 

[Sidewinder]

Dunno Marvo, but I find the kit I have well made & it works!

Some good looking gear there I must say , Slidey but I'll stick with the chisel if the grips won't get a grip,  remembering that the L/nuts today are 1/2 the thickness of the old ones.

As are the brass bushes.

 

[kerching]

I've used a set of these...the bush/ nut set.

Very good, well made. I believe they are made in Sheffield .

Might buy one of the lock ring jobbies

while we're on the subject.  Tightening them up would be alot easier if glands had a larger nut intergrated into them.  Something decent to get some grips or a spanner on.
