Rated 3.0 out of 5 by 2 reviewers.
Rated 3.0 out of 5.0 by Need to be able to order extra parts or additional engineering needed. Directions are in metric, with incorrect inches conversion. No way to purchase parts from the company and sending the stairs back would be problematic. Ex: My stairs needed to be built 93" high, which is too short for two internal poles plus the threaded rod, but too tall for one pole plus the threaded rod. I had to search 10 places over two Saturday's to find additional 20 mm threaded bolt and connecting sleave. As a result I also needed an internal insert to accompdate the threaded pipe. Did Arke have any parts to order?, no. So I had to glue in a PVC bushing (2"x1/2") with epoxy glue (PVC cement won't work I tried it). All in all a nice stairs. Their engineers need to; make the threaded rod longer, a way to connect two threaded rods or one of the structure poles shorter with the longer threaded rod. July 10, 2012
