Mounting: Panels to 0.125" (3.18mm) thick with 1/4-32 bushing and hex nut ( 1/16" thick). Model C Model e Dimensions for reference only; consult factory for details. Since all rheostats/potentiometers are electro-mechanical devices, they are subject to mechanical wear and, therefore, have a finite life. Models H, J, K, L and N are listed under UL File No. E-10946 and CSA File No. 21309 unless noted otherwise. All rheostats are 10% tolerance.
