A shelf section adapted to fit against a wall section where there are exposed 2×4 wooden posts at spaced intervals. The shelf section has a horizontal platform, part of which is positioned between adjacent 2×4 posts, and the other part extending outwardly from the posts. A pair of mounting flanges attach to the outer surfaces of the 2×4s, and a pair of braces extend between the flanges and the platform. The shelf section is designed to be made from a single metal sheet cut to the appropriate dimensions and configuration, and is arranged so that a plurality of shelf sections can next within one another for storage, transportation, etc.

The self adjusting closure apparatus of claim 1 wherein the tool further comprises a main spring urging said movable jaw open and said push link rearward against said at least one friction pawl and wherein the force of said back spring against said at least one friction pawl is adjustable to offset the force of the main spring whereby the linear position of said push link and said at least one friction pawl relative to said support rod can be adjusted. 3. The self adjusting closure apparatus of claim 1 wherein said second end of said push link bears against the frame. 4. The self adjusting apparatus of claim 1 wherein when said push link is in said first position it contacts said at least one friction pawl at a second point, opposite from said first point relative to said support rod axis, urging said at least one friction pawl to return to said substantially orthogonal position. 5. The self adjusting apparatus of claim 1 further comprising a means of adjusting the relative angle between said push link and said at least one friction pawl when said push link is in said second position whereby the grip force applied by the tool to a work piece is adjusted. 6. The self adjusting of apparatus of claim 5 wherein said means of adjusting comprises a wedge interposed between said first point of contact and said at least one friction pawl. 7. The self adjusting apparatus of claim 6 wherein said means of adjusting comprises means for adjusting the position of said wedge relative to said push link whereby the thickness of said wedge at said second point of contact is variable. 8. The self adjusting apparatus of claim 7 wherein said support rod mounting allows rotation of said support rod about said longitudinal axis and wherein said means for adjusting the position of said wedge comprises slideably coupling said wedge to said support rod whereby rotating said support rod moves said wedge relative to said push link. 9. A self adjusting locking plier comprising: a) a frame; b) a fist jaw fixedly attached to said frame; c) a second opposing jaw pivotally attached to said frame; d) a main spring, coupling said second jaw to said frame, urging said second jaw toward an open position; e) a handle pivotally attached to said second jaw; f) a push link pivotally coupled to said handle at a first end and bearing against said frame at a second, opposite, end, having an opening defined through said second, end, having a transverse ridge aligned with said opening; g) an extended support rod, mounted to the frame, and passing through said opening in said push link, said support rod having a longitudinal axis; h) at least one friction pawl, having an opening defined therethrough receiving said support rod, positioned immediately adjacent to and rearward of said second end of said push link, i) a back spring, bearing against said at least one friction pawl, urging it in to contact with said push link at said ridge; wherein closing said handle by moving said handle toward said frame urges said push link rearward against said back sp
