Abstract: A portable apparatus for supporting and maintaining fascia in proper position during installation upon the exterior of a building, such as a residential dwelling. A forked member is temporarily attached to the eave of the building. A cross member is connected to the forked member. The vertical position of the cross member, relative to the forked member, is adjustable and temporarily fixable. A support member, upon which the fascia rests and is supported, is connectable to the cross member. The horizontal position of the support member, relative to the cross member, is adjustable and temporarily fixable. By selectively adjusting the horizontal position of the support member, and by selectively adjusting the vertical position of the cross member to which the support member is connected, the position of the support member, and thus the fascia, is precisely adjustable in two dimensions. The apparatus thus permits the fascia to be held in proper place while the user permanently installs the fascia to the building.

Abstract: This invention provides a novel apparatus and method for securing a work object, such as a pipe, conduit, bar, rod or the like, using a wrench or other gripping tool that acts as a second set of hands.
