McAlpine Mechanical Pipe Boss Connector Black 40mm is rated 4.4 out of 5 by 24.
Rated 5 out of 5 by from Made the right choice! Me and my mate bought a strap boss to do for the task but once up on the roof we quickly realised that we had bought the wrong product after a quick hunt about we found this device! It was perfect for the job. After cutting the hole into the cast pipe it slid straight in one of the best things on the market. There is a YouTube video showing how it's done and its very simple

Rated 5 out of 5 by from Easy to fit Drill 56-57mm hole in stack, put fitting through and tighten anti-clockwise using the tool supplied - simple. Once fitted fix 40mm pipe, in my case to take washing machine and dishwasher waste water. Very clever and am happy to recommend.

Rated 5 out of 5 by from Easy way to add a small waste No need to fidle with a strap. Cut the hole with a big cutter. Insert though the hole from the outside and tighen it up to give seal from the outside with the tool provided. So easy!

Rated 3 out of 5 by from Service life I installed on of these in Jan 2015, and it has started to leak in April 2018. The rubber bung that is compressed to make the seal seems to have become very hard and no longer deforms as needed. The result was a steadily increasing escape of foul water. As a repair I tired to seal it using silicone, did not work so I replaced it with a new unit whose bung is much softer, hoping it will out last the first one. Maybe the bung could be an available spare part I agree with all the reviews about how easy it is to fit but lack of service life could be the trade off.

Rated 4 out of 5 by from Soil pipe connector If you want a leak proof connection onto a soil pipe then this is the perfect product. Far better than a boss and strap . Quite pricey but reliable .

Rated 5 out of 5 by from Simple fit Nice and simple piece of kit to fit. Worked a treat with the 57mm hole saw(also purchased from screwfix). Also a lot cheaper than similar kit from well known diy store.

Rated 1 out of 5 by from who writes reviews I'm a McAlpine devotee and really wanted and needed this kit to work but really, unless I'm missing something, it's just not fit for purpose. Been in plumbing trade man and boy, before I'm judged, can only see me trying for a refund as this is useless
