Secure-A-Tank toilet tank brace

Secure-A-Tank consists of four clear plastic parts that fit together to make two sturdy braces that hook over the lip of the toilet tank. They rest solidly against the wall to fill the gap and prevent any pressure against the tank from moving it and causing cracks or leaks. Place one of the extension pieces against the wall and mark where it touches the tank. Cut it to that length, then snap the extension into one of the clip fittings and hook it over the edge of the tank.
