Question: Does this product require 24 inches of wall space to mount (is it 24 inches wide?) or 21 inches?  One thing says 24 inches, one says 21 inches?
Document: With the dimensions of 24 inches, I expected the distance between the screw holes to work on our 2' studding. However, the distance between the screw holes is 22 inches. Fortunately, we were able to add some support structure to allow us to hang the Polder Wall-Mount 24&#34; Accordion Clothes Dryer.
It does the job to get the clothes drying rack out of my bedroom and hung on the wall in the laundry room. It is not very wide so larger shirts do not hang on it as well as they due on a full size. It says it only takes 20 lbs of weight which works out because not very much will fit on it at once. It might have benefited me better to order two instead of just one.
Cloth diapers require line drying, but living in a tiny apartment the last thing I had space for was a drying rack. This folding rack saved space and time. I hung it right above my washer and dryer. I wash the diapers. With one hand I pull out the rack, hang, and return to my daily life. No need to store the rack in a closet, have to pull it out, go back to get the diapers, then hang, and so on and so forth.
This is a nice wall-mounted clothes rack. It is made of sturdy white plastic with shiny silver (chrome-like) hinges. It is 24&#34; wide and sticks out about 5&#34; when fully collapsed.
Great product. Hangs lots of cloths to keep a small space less cluttered. The only thing I would advise is to use your own wall anchors. The ones provided break off easy. You can find stronger anchors from your hardware store. This rack is fantastic and a space-saver. I have two.
This is a must-buy for people looking to wall mount a laundry hanger.Collapses relatively close to the wall, maybe about 4 inches sticking out total when its collapsed.Wall mount brackets are made so that you can install the brackets to the wall and take the rack on and off the mounts fairly easy.
This is a very nice rack. It is plenty sturdy for wet clothes if properly installed. At least one side needs to hit a stud. If you can manage to get both sides into a stud, you could probably hang a lot of weight from this.When closed, it sticks out about 5 inches from the wall.This is a great addition to our laundry/mud room.We only use it for hanging some of my wife's undergarments and other swimsuits. We put most everything else in the dryer.
Frustrating, but I moved the mounts down an inch or so and perfect-o! It folds neatly back against the wall. I have loaded this thing up with running pants and tops, one article of clothing per rod. So far it is not sagged down or shown signs of not supporting the weight.
I bought one of these and liked it so much I bought another and installed it below first unit. They are surprisingly strong for how lightweight they are. They are easy to install, and due to slide brackets you can remove the whole thing if you ever want to take it off the wall. So far these have been a great addition to the laundry room.
I wanted to install this product under a cabinet in my laundry room. The installation directions require mounting a bracket and sliding the product in from the top, which takes at least 5" of clearance above the bracket. I solved the problem by drilling holes in the product aligned with the holes in the mounting bracket. This a permanent installation and the screw heads show, which is fine with me. Do make sure that you attach it to a wall stud or other solid surface on both sides and hang it level.
Answer: rack requires 24 inches of wall space to mount.rods are about 21 inches wide but wall mounts are wider.
