I I had purchased 2 set's of these hand rails. The steps are fairly easy to assemble and have a fair amount of adjustment for 4 or 5 ssteps. You have to be careful you get pole 1 and pole 2 in correct position and you need to pay close attention to instruction and illustrations you get. One top hand rail had flaws in the black refinish than the other one which was perfect. All in all these are very nice hand rails
