    Hi guys,

    what size hole cutter do I need for a strap on boss. I'll be using one for both a 40mm and a 32mm waste pipe.

    Cheers

    I'm looking at a strap on boss now; if you look on the inside where the back of yhe plate will attach to the soil stack there is a raised circle that goes into the drilled hole - that might be a bit of a giveaway.

    unfortunately, I dont have a strap on boss with me, i'm ordering a load of stuff, including these, and I need to order the hole cutter at the same time, and need to make sure that I order the right one.

    I think it is plus 4mm for each. The ID (inside diameter) is 40 mm.
