Jennifer. In Australia we have Australian Standards. The Australian Standard for Dissability Access calls up the relevant Standards for Grab rails. Now you may be trying to raise money & in that vein save money, but to have, even proffessional welders manufacture thes grab rails is a effort in futility because the grab rails WILL NOT meet those Standards & you or your committee have not met your duty of care.
Grab rails are readily available from REECE Plumbing Supplies and are not expensive as your Liability insurance will cover them.
