We purchased this to mount in an upper cabinet. Keep in mind it is designed for a lower cabinet. Once installed, the distance from cabinet floor to the bottom of the rack is about 3” to account for the heavy duty hardware—-You lose some vertical space. Although Ive found a low profile pan fits nicely underneath. This is a very sturdy rack with a very smooth sliding hardware. UPDATE. Weve been using this rack for over 2 years. Its been very practical, holding up well and holds lots of stuff! Very pleased
