The holder can be used for two ranges of panel thicknesses. Factory ship-
ped, the holder is configured for mounting an operator in 1 to 4 mm (19 to 9
gage, 0.039 to 0.157 inch) thick panels
text and arrows on the holder pointing toward the panel and with the tighte-
ning pinion in the bottom right-hand corner.
To reconfigure the holder for mounting an operator in 3 to 6 mm (11 to 4
gage, 0.118 to 0.236 inch) thick panels, with the > 3-6mm > text and arrows
on the holder pointing toward the panel, the tightening pinion must be tur-
ned counter-clockwise to its stop.
