Avoid a wrong match
- Do not treat JSID or JSIJ as the ordinary single-rod JSI configuration
- The S option does not create a separate public page
- Confirm the complete ordering code before quotation

A similar body does not guarantee the same function. Confirm the function and interface first, then compare size and installed dimensions.
Read the model code
If the label is incomplete, send the readable parts together with a photo.

About JSI
The JSI family covers three mechanically different standard-cylinder configurations. JSI is single-rod, JSID is double-rod, and JSIJ is double-rod with adjustable travel. The S suffix is treated as a magnetic option in the code context, not as a separate page.
