Round conduit box lids.

[Chris1234]

Evening, is there a place to get good quality 20mm round plastic conduit lids?
I’ve installed a load this weekend from Screwfix and they don’t seal correctly as the plastic is too thin.
I’ve ended up using two lids on each box!

Thanks.

Call in another wholesalers and see if theirs are any better. Plastic lids are ten a penny....they sound like a hundred...….or in your case fifty a penny

Get some rubber gaskets to go with the lids

You need a better quality lid which are usually thicker or use metal lids and a rattle can of white paint ;o))))

Centaur lids have a built in 'seal'....and fit as well as any other brand.

 

[Chris1234]

Thanks, they have a rubber seal, but they seem to be tightened too much when you buy them. The screw hole is slightly lower than the level of the outside rim so they are bent outwards in between the screw holes.

The one item I buy from CEF!

Thanks for the above.

After 5 weeks all the screws are rusty as well

I use Marshall Tufflex (I think.) With separate rubber gaskets and brass screws.

Not the cheapest way to do it but it works for me.

And always fitted with M4 x 8 brass screws.
Swap the screws on the saddles for stainless as well.

Brass screws are the way ahead.

Ours come from either Electric Centre or Edmundson which are MK and have no problems with them.

Marshal Tufflex lids are pretty good, though they don’t work well with rubber gaskets.
They have a raised boss around the inside which locates the lid in the box, but prohibits using gaskets.

The gaskets I use are the full size of the box and I can't say I've noticed an issue.

I'll double check the brand of lid in the morning.

I over ordered a year or so back so have squillions of the damned things.

The ones I’ve used have 2 spikey bits sticking out to locate over one of the screw lugs in the box as well.

Where did you buy your gear from?

Screwfix, never again.

Thin conduit lids that bend before they are tight and let in water, and screws that’s gave badly rusted in 5 weeks.
The lids have delaminated as well.

Wow that sounds terrible, I’ve only ever used MT and Centaur..
What make do screw fix sell?

Tower, which I thought was a good brand. One of the online videos' someone done regarding bending of the conduit and it splitting and breaking. I think that it is light gauge.

Yep I know not to use them from there again after using them on a job before. Had to go to a proper wholesalers the next day to get proper replacements to fit.

Makes you think how they pass quality control.

Mind you I use the likes of Screwfix/b&q etc very very rarely only as last resorts.

The quality is poor for a lot of things, Schneider heavy gauge plastic conduit is the most recent problem causing conduit item for us. The bore of the conduit is now off centre leaving one side of the wall much thinner than the opposite side. This has lead to problems with bulging and distortion when bending. This is not just a one off bad length of conduit either, we are on bundle number 7 now with the same problem. Getting sick of using it now.

Tower which Screwfix sell is now part of the Schneider brand we have had this problem with other brands. The PVC conduit sold under the Schneider brand used to be Miter (if I spelt that correctly) which used to be high end.

Mita.

Sadly Schneider ruin a lot the products of the companies they take over. Look at what a mess they made of Merlin stuff.

Used to install their type B distribution boards about 8 years ago and they were a good board with the slider bar. Recently we had to fit an MCCB board with meters on each side it was terrible compared with Eaton load of leads to connect where Eaton one supply cable pre-made plugin leads between meters and a cat 5 from the meter to CT's. How have they made a mess of the Merlin board?
