Glides are for use on hardwood flooring and carpeting or rugs.
A Note on Dimensions
The complete or overall height of this glide is 3-5/8". However, the top 7/8" of this glide will insert into your bedframe. This leaves 2-13/16" of the glide actually contributing to the height of your bedframe. (Please see "Actual Installed Height Dimensions" under More Views.)
If you are replacing the wheels on your frame with glides, you will need to use Steel Stem Glides, which are designed to allow easy replacement of casters or wheels on bed frames. Click Here
