Supplier of these base plates please

[RobertLambie]

I might be wrong, Ian. But I don’t think that is a signpost system, mate.
However, that is easy enough made, but those screws into tar wouldn’t give me a lot of confidence.

You can buy these base plate type connections easy and cheap enough.

The posts will be 50mm scaffold-type posts, but to do it right you want 50mm Galvanised steel or plastic coated.
Whatever base plates you buy, make sure the hole will accept the diametre of post you are using.

Screw, I would advise on the Thunderbolt type concrete screws attached. You can get this type from Amazon, Screwfix etc.
Get the ones in the photo with the wide threads, particularly if you are screwing into tar, and get 100-150mm long. again, check the holes in the base plates will accept the screw size or you may have to widen them.

Righton/Blackburn will sell you the 50mm posts. Ask for them to come with plastic caps, as it finishes them off nicer.
They will also cut the posts down to the size you want.
Righton will also sell you the channel and post clips for the rear of the sign.

That was my response to the enquiry but they don’t want holes dug into the ground. As for the fixings I was was going to use rawlbolts rather then thunderbolts as at least they expanded in the ground. Or even chem fix them into the ground.

I would chem-fix the thunderbolts – drill, blow dust out, chem-fix in hole, slam in thunderbolt, post going nowhere!!

i have always hated the expanding fixings like rawl bolts. always found them a hit or a miss to work with and never looked forward to these types of jobs with the uncertainty at the back of my mind.

Chemical fixings are probably a good option here because of how tar is made up and what’s below it. so you are most likely to get a better fixing with the liquid fixing.
