Ultramount Junior has the same beefy 3/16" thick steel construction as the standard Ultramount, however the Junior is only 7-1/2" tall. With Ultramount JR being only 7-1/2" tall, some press linkages will hang below the benchtop to impede opening of cabinet doors or drawers below your bench. If you have any doubt, before placing an order, measure the linkages hanging down below your bench top and subtract 7.5". If you want to have the press completely on top of the bench and be able to push it back a bit, the standard Ultramount 9-3/4"with quick change base will fix you up. This base set up is to be used with InLine's quick-change top plates. You need on Mfg: Inline Fabrication
