The metal plate at the back of the Safety Rail uses the same bolts that the toilet seat uses to attach to the toilet bowl. (No added hardware to buy.)
This product does not have the "front bar" but rather the two legs which rests on the toilet base -- I have one on both an oval and "round" toilet -- works fine for us.
Hi GatorRay. The Drive Toilet Safety Rail, mdl # rtl12087, has a fixed height of 12 inches from the rim of the commode to the top of the safety rails. For more information, you can also contact Tech Support at: 1-866-621-4933. Please let us know if we can be of further assistance. Rick_HD_OC
