Havis universal tablet cradle. Very heavy duty and made entirely of metal. Sections on the left and right extend a little for longer tablets, so the width is somewhere around 9 to 11 inches wide. See pictures for accurate measurements. Both keys for the extension release are included as well as the fastener kit and owner's manual. Please make sure this will meet your needs prior to purchase. Sold as is, we will not accept a return if your equipment doesn't fit.You can purchase an optional Desktop Stand accessory elsewhere but it is not included with this set. May or may not be shipped in original manufacturer's box.
