T-155 is a brass plated glide that elevates the bottom of a trunk approximately 1/2" above the floor.. Overall measurements are 1/2" high by 2" wide by 1 3/8" long. If you would like for the glides to not be seen, try placing them a little further into the center of your trunk. Their low profile makes them easy to hide. Just make sure that they are not placed too far in as that will make the trunk less stable.
