ABSTRACT:
A guide for slidably accepting opposite edges of a sheet of material which may be an electronic circuit board or metal plate attached thereto and which makes use of a rotating camming bar in a retainer as a clamp has rotational stop and drive means built in a way to minimize servicing and replacement problems. On those occasions where the stop and drive means are pins, the bar and pins can be assembled prior to insertion in the retainer and bars can be individually removed and replaced. The pin relationship is furthermore such that any relative weakness in the structure is relegated to an exterior more easily accessible location to avoid unnecessary disassembly of parts when a bar needs repair or replacement.
