Abstract
Abstract Fixture apparatus for use in applying vertical transformer spacers to a flat surface. The fixture includes a frame and a plurality of movable bars. Slots on the frame guide the movable bars while the fixture is being adjusted. A scissor-like linkage interconnects the movable bars so that all adjacent movable bars have the same separation distance. The transformer spacers are placed into channels in the movable bars with adhesive applied to their exposed surfaces. The flat surface is then placed over the fixture and the spacers.
