Just fitted my first frame to support a wall hung WC. The frame was supplied with two 3/8" lengths of threaded stud to support the WC. The WC has two approx 3/4" inch holes in the ceramic casting for fixing. No manufactuers details supplied on how they recommend the WC to be supported. Just hanging on two small studs through oversized holes does not seem right to me. Would appreciate some feedback from anyone who has had experience of fitting these.
