I’d need to cut a hole for a toilet drain through an already sistered 2x8, and could reinforce the hole with this steel offering. They claim its even stronger than before the hole was cut.
Would that be acceptable under Ontario Building Code?
If you are planning a bathroom renovation in Ontario (Canada), that requires movement of a fitting such as a toilet, it needs a permit, and it should be carried out by a licensed plumber. The plumber would then be responsible for ensuring the correct support was installed and you would not be held liable for faults if and when you come to sell.
