McAlpine Mechanical Pipe Boss Connector Black 40mm
simple to use
a 57 mm hole is OK but 56 would be better, at 57mm the pipe can easily be dislodged - do 56, see if it's tight, if not you can easily file / sand a little away, but not much you can do apart from silicone if its too big!

Neat but odd
Looks nicer than the conventional strap connections but has a 5 degree fall unlike the conventional 2.5 degree. Not a huge problem but would have been nice to know beforehand. Not able to confirm reliability so have just rated 3 stars

So much easier than messing with a strap on boss and solvent welding it. This is dead easy to use and quick too.
Just drill the hole and tighten it up. Compression connection for 40mm or 1 1/2" pipe.

forget a strap boss, get this
if you have ever faffed around fitting a strap boss then you know what a pain they can be.
after fitting this item I will never buy a strap boss again. just drill the hole push into place and tighten and that's it and if you ever have to remove it for any reason just do the reverse. simples.
what really finishes it off is not having to try and get your pipe to fit in the rubber bung as this item comes with a compression fitting. love it.
