Abstract
A spacer holder arrangement includes a support sheet of a self-supporting nature, at least one side of the support sheet having a low adhesive-bonding ability. A pair of concentric inner and outer spacer elements of an annular shape are disposed on the one side of the support sheet to provide a performed spacer, each of the inner and outer spacer elements having adhesive layers formed respectively on opposite sides thereof. One of the adhesive layers is interposed between each of the inner and outer spacer elements and the support sheet to bond them releasably together. The inner spacer element has a central hole therethrough which is coaxial with an aperture formed through the support sheet so that a guide rod can be passed through the aperture and the central hole.
