These sliders are a 'Safety Feature' for older people.  Before installing these I would have to bend over
and stand with my head upside down while sorting through the cleaners. Not only the bending over but
the reaching back so far made it unpleasant. often times as I stood up I would feel dizzy and have 
to hold on to the counter to get steady on my feet 
 I had no idea they would actually be a safety feature but they are.

 Thank You wayfair.
