The two opposing green plastic inserts including rod is secured centrally to each other by means of a small screw; Thus, there are two different types of inserts, one which receives the screw and having one of an opening for the thread of the screw.
Unfortunately, one of the two columns 3 plastic inserts for screw-receiving and only 1 matching counterpart were present, which is why I had effort to cut a small dowel and manage to stick, so the whole thing works easily without complaint. Because of a lack of final so I subtract a star.
Tips:
- The screws do not overtighten, otherwise tearing the green plastic
- I have the two green pillars cover reversed because the top with an opening for suspension has and I consider it more appropriate to place this cover "down" to allow any moisture to escape better in heavy rain
For the price, the set is in order; I would get me again at any time. I'm curious how long they keep and the Frost survive.
