<p>Adjustable holding systems (100), as well as methods of using, may include a fixed base (102,2302) adapted for use on a work surface (702), the fixed base (102) having a rear actuated clamp assembly (108A,108B) secured thereto. Other systems and methods may include one or more bases (102,1502) adapted for use on a work surface (702); and a guide assembly (104) removably securable to the one or more bases (102,fig 1; 1502, fig 16), wherein the guide assembly (104) provides infinite vertical adjustability which can be retained without clamping. Yet other systems and methods may include a portable base (1502) securable to a work surface (702, fig 21), the portable base (1502) having a portable base opening.</p> |
