Fill unused holes in Henley block

[pc1966]

I might need to remove an old heater CU leaving some cable holes in the Henley block where its tails currently go. Anyone got a good suggestion for an insulating plug for those holes?

There are propper little plugs for it, but I have no idea what they're called

I found this Weatherproof Plastic Compound 1kg - https://www.cef.co.uk/catalogue/products/160802-weatherproof-plastic-compound?gclid=EAIaIQobChMIrpjPz_OO9wIVQYBQBh3yuAYREAQYBSABEgK7lfD_BwE&gclsrc=aw.ds

These may be too big, and if not, probably too expensive ??

I thought this looks like an opportunity for 3D printing, and sure enough: 20 Pack, Henley Block Blanks/100a connector blanks | eBay - https://www.ebay.co.uk/itm/185254582641?

I see golf tees and plastic rawlplugs get suggested, along with silicone sealant

Are they 25mm holes or 35mm?
I found this, though it's a bit home-brew 3d printed...

Had some locally produced beer at the brewery after a day actually went to plan for once. Forgot the "square mm"!

Fit new.

A thin plastic shim can sometimes be inserted between the brass block and the casing of the Henley block

too technical (unless it can be inserted with a hammer)

25mm I think.

Shame it is 20 as I probably will only need 2 for the next 5 years...

That is plan B...

The Hager 100A blocks come with replaceable blanks… so same idea could be used on an existing block

Have you a link to them? I have only ever seen their 20-30A junction boxes and the "neutral link" MCB replacements for the likes of adding SPDs, etc.

My mistake. They’re Proteus.

Like I said, removable blanks (I think 3, so there’s always 2 open holes) and there’s a little block can go in the side so you can screw them up side by side neatly as they’re fixed together.

Wow. I didn’t notice that.

Never had a problem getting them in the past, and I think I’ve got a grey one floating around the back of the van.

I'm used to CEF having damn-all in the store, but odd to see them out of stock for delivery.

I was thinking the same as they are quite cheap and about the right size

Talk nicely to the next passing electric board man you see, the local SEC guys have them as standard van stock items and are happy to give handfuls away if you engage them in a bit of banter.
(same trick applies to the BT gel crimps if you see someone working in a telephone exchange box)

Find a 'short' offcut of 25mm tail, form it into a U shape and install one end in each of the two vacant holes.

Donning some PPE before doing so of course.
