A stainless steel locating ring can be used as a retaining collar to position a FIREROD if mounting requirements are not critical. For LA, specify the location if the no-heat extension option is requested. On FIRERODs with crimped on leads without the LA option, the locating ring will be located on the last 1 / 4 in. (6 mm). To order, specify locating ring .

Stainless steel flanges are a convenient mounting method to position a heater within an application. The flange is staked on and located 1 / 4 in. (6 mm) from the lead end. The flange can be located up to 2 1 / 4 in. (57 mm) from the lead end if it is over a no-heat section. Use this option in

combination with most LA configurations. To order, specify flange , size and locations. Flange Specifications
