I've run into a couple of situations now where I need to cut into a vertical stack to either replace a damaged connection or re-route the stack. In both cases, however, the stack runs too close to a stud to use a riser clamp near the repair junction. Is there another solution, or am I just exhibiting my natural ignorance in not being able to figure out how to make the riser clamp work? I suppose I could go all the way up and install the clamp on top of the ceiling joist (even removing the vent pipe to just below the joist, too, since it's all galvi and heavy as sin), but so many of the illustrations I've come across show the clamp braced in the wall that I was wondering if I was missing something.
Thanks in advance for any advice.
