I was just reading the thread about jonathan ellis and saw that one of henrys guys just fell off a roof and thought it would be a good time to post this.
In many an older home this drain pipe is perhaps 4 inches in diameter and stays that size all the way through the roof.
The main vent is stack is often but not always a continuation of the soil stack which is a 3 or 4 inch waste pipe that extends vertically down from the uppermost bathroom to the sewer.
Your home s plumbing system is designed to efficiently remove water and waste.
Its drainage and vent functions are actually two systems.
That peice of roof anchor can be the best built peice of metal on earth but you are putting more faith in the vent pipe holding secure.

I would not use a pipe anchor on a high pitched roof it will pull up as the pitch increases.
You have to carry some black jack with you and fasten it up under the tabs black jack the holes and put the tab back when done as to not cause a leak.
Other vent pipes that are smaller may connect to this full sized vent and that s perfectly fine.
For pricing and availability.
A full sized vent is a primary vent where the drain line transitions at some point and becomes the vent pipe that exits the roof.
We charge for the anchors too 50 per anchor installed.
