(³/32" thick) (or with 10-32 x 0.75 flat-head screws for model L only).
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.
