This is a listing for a pair of ONE (one of each side) tablet mount designed for USG/ICON(IC) toolbox hutches. This item was designed to fit many tablet sizes with an interior diameter width of 18mm accommodating most tablets/phones on the market with no case, or a very slim case. You may place each piece in your desired hutch slot to create the desired width you need for your tablet, or even phone or laptop if thin enough. This also may be used to hold a portable 15" laptop screen to increase viewing size.
