LOCATING PEGS (anti-rotation lug)
The locating peg is provided by a plate mounted on the bushing
and positioned by the module sides. Four set positions are
available, clock face orientation: 12, 3, 6, 9.
CODE
All 148, 149 bushings have a double flat. When panel mounting
holes have been punched accordingly, an anti-rotation lug is not
necessary.
