Abstract
A precision rectangular fixture frame includes top, bottom and grooved side members. A middle bar of the frame parallel to the top and bottom members has a pair of recesses aligned with opposing recesses in the top member whereby a single vertical bar having a pair of spaced notches can be interlocked with the top member and middle bar of the frame in two positions of use parallel to the side members. The vertical bar is grooved in its opposite sides whereby in each position of use of the vertical bar one of a pair of contact gage and alignment bars can be supported at plural elevations on the fixture frame during servicing of successive ranks of contacts in two distinct areas of an upper tier of contacts in a receiver. A third contact gage and alignment bar is employed without the vertical bar and is engaged with grooves of the frame side members at plural elevations during servicing of successive ranks of contacts across a lower tier of contacts in the receiver.
