If the wall braces will not work in your bathroom, the p0616 unit is a bracket kit that will allow you to brace the supply lines to the Strom Plumbing 1 3/8" OD tub drain rather than a wall. If you are using a 1 1/2" OD drain in use with the above listed Strom Plumbing Freestanding Supplies, you can use the ecfssbrace.
Please Note: The roughing-in of clawfoot tub freestanding supply lines will depend on the centers of your faucet body (Eg. If you have a faucet that measures 7" from center of hot line to center of cold line you would rough-in your supply lines 7" from center of hot line to center of cold line).
