Rectangular washer for facade substructure - has two pegs for insertion in component and two holes to guide drill

摘要

The rectangular supporting disc or washer (1) has two pegs (4, 5) projecting from its lower surface which are used to position the washer in the oblong hole of a component for e.g. the substructure of a facade wall. The distance between the furthest faces of the pegs must be equal to or insignificantly less than the maximum length of the hole. The holes (2, 3) in the washer are arranged in a line with the pegs and at an equal distance from them. These holes are used to guide a drill with which the second component is to be drilled. The washer and pegs are e.g. manufactured in one piece from polyethylene which will exhibit a limited coefficient of friction between the two components.
