Abstract: A mountable support and vice device for field use in small work areas includes a fastener, which is attached to a first terminus of a rod. The fastener is selectively attachable to an element of a structure, such as a scaffold, to removably attach the rod to the element of the structure. A pipe is nested around the rod so that the pipe is selectively extensible from, and selectively rotatable relative to, the rod. A coupler attached to the pipe and is positioned to selectively couple to the rod so that the pipe is fixedly positioned relative to the rod and the element of the structure. A vice is attached to the pipe proximate to a first end of the pipe and can selectively grip a substrate, such as a pipe elbow. The substrate thus is fixedly positioned and can be manipulated by a user.
