breaking into 110mm soil pipe

[spion]

Hi. I am new to the forum and could use your help.
I have a vertical 110mm stack pipe sevicing an upstairs bathroom and I want to install a toilet downstairs. How can I cut the pipe, install a branch fitting and secure a leakproof joint to the vertical pipe? Once cut the pipe will not move up or down to slide into the new fitting.
Any help would be appreciated.

Sorry. The vertical stack is 110mm plastic.

1 x 92.5 degree branch - 2 x 110mm flexseal ( fernco) connectors - 1x throw away handsaw

or use 110mm slip collars, lubricate and slide the collar up the pipe, insert the branch and cuts of pipe then slide the slip collar back down, making sure it is positioned correctly 50% either side of the pipe

Thank you. I didn't know these fittings were available.

This method would look nicer than using Furnco collers, both methods would achieve the desired result though, good luck

I was assuming internal soil boxed in -
