I was able to assemble the rail without much trouble, even though the plastic bag with small parts had opened during shipment. I did not have any missing hardware items. A very crucial bit of information was not provided, the concrete anchor drill size. In reading the reviews some had suggested a 3/8" drill, which would be too small, and others suggest a 1/2" drill, which would be too big. I followed theadvice of a reviewer and bought a set of 3/8" concrete anchors and the required 3/8" drill. I did need to ream out the base plate holes to 1/2" to accommodate the larger studs. I had noticed the fine print in the instruction sheet regarding NOT tightening completely all other fasteners until after the base plates were tight. This is a very important point The final result is a sturdy and nice looking stair rail.
