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.
