Abstract: The handle of the present invention is formed from a sheet of pliable material having a periphery with two opposed convex edges separated by two opposed concave edges. Two parallel fold-lines join the concave edges. When the sheet is folded, the body forms symmetrical walls that are fastened together using a tab, located on the edge of one symmetrical walls of the handle, and a groove formed on the edge of the second symmetrical wall of the handle, for receiving the tab. In its folded state, the handle resembles a taco shell with a bite taken from each end. The bite resemblance is formed by the two opposing concave edges and help to limit the length of the flat base formed by the space between the parallel fold lines. A correct base length allows the bag handles to naturally droop from the weight of the contents, so that the taut bag handles do not cut through the pliable body material or weaken the base.

Abstract: A frangible insert that is inserted in a pre-positioned bushing in the wall of a manhole form from the convex, easily reached side of the inner form wall. A key in the insert is received in a keyway in the bushing in the form wall so that the insert is properly oriented in the form. Concrete is then poured into the form, enveloping and affixing the insert within the man hole wall. A weakened, frangible region is provided on the insert in a position immediately adjacent to the form wall so that after the concrete is cured, the manhole and form can simply be separated, causing the portion of the insert embedded in the concrete to separate from the insert portion in the form bushing.
