Mounting:

Panels to 0.25” (6.35mm) thick with 0.375-32 bushing and hex nut

(0.094” thick) (or with 10-32 x 0.75 F.H. 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 Reexamination Service File

No. E-10946 and CSA File No. 21309 unless noted otherwise.

All rheostats are 10% tolerance.
