Question: How many are in a package?
Document: So I ordered two packages. They arrived today and they are just one piece--a glider with a nail shank. The package does not look like the package shown when I bought them. Today there is no picture of the package--just the item. Wasted my money.
(The sliders did not wear out on other chairs used over carpeting that were only moved occasionally. )July 2013 I ordered another package with the same product #08221, but was disappointed when I received one piece sliders with the nails attached. With the new design the sliders may last with chairs used over carpet. However, they will not work for me over my tile since I doubt I will be able to keep using the same nail holes over and over again when the sliders need to be replaced.
Really good. They stay on and don't leave horrible scratch marks on the floorlike so many others do. So happy I switched to these.
does exactly as it states...pretty simple. can't describe this any other way. if you need them, this works for you!
Yes, I want them to last forever; maybe if they were a little thicker (hint, hint)?
Works just like they say, it is a one peace nail on glide, if using on smooth surface works great it is not made for rough or uneven surfaces, on my deep carpet it makes it easier to pull out chairs but when you sit in chair they sink into carpet they can't stop that, but they do make it better to move the chair.
We purchased these as a replacement for sliders we installed a decade ago. The old sliders were worn out and a few of the &#34;holders&#34; had to be replaced. There is a little trick to placing the sliders on to the holder, but it was an easy project. The best part was that our chairs were sliding again! (in fact until they wore in a little, we would sit at the table and the chairs would slide away!)
We love these. We had a couch with feet that marked the floor when we turned the couch between TV watching and social settings. We tried felt pads and they were better, but still left some marks. Now, we have no marks and my wife can turn the couch while I'm sitting on it and I can turn it empty with fingers.
We had these on our dining room chairs on a wood floor. They seemed great at first, but over time the nails protruded through the plastic on the back legs, which left terrible marks on the floor.
This product did exactly what we needed it to do...prevent wood TV trays from scratching our flooring. Easy to apply
Answer: yes
