This design is shaped to fit both cases rather than needing a separate adapter.\u003c\/li\u003e\n\u003cli\u003eThe lockout has two separate lock holes, so two different workers can each apply their own padlock to the same isolation point. Neither can remove the cover and re-energize the switch until both locks come off, which supports a two-person or dual-authorization lockout procedure on one control point.\u003c\/li\u003e\n\u003cli\u003eIt’s built around Siemens’ housing profile, so a close but non-Siemens shielded switch should be checked against the total and inner diameter measurements before ordering. A mismatch in shield height or diameter can leave gaps a standard lockout wouldn’t have.\u003c\/li\u003e\n\u003cli\u003eThe transparent PC construction lets supervisors see the switch’s position and any labeling through the cover without removing it, which matters for quick visual verification during a lockout audit.\u003c\/li\u003e\n\u003cli\u003eProlockey makes several emergency stop lockout variants for different diameters and mounting styles. The SBL01\/SBL02 series covers 22.5mm-30mm switches, and SBL07-08 covers 22.7mm-29.8mm, if this one isn’t the right fit.\u003c\/li\u003e\n\u003cli\u003e{ \"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [ { \"@type\": \"Question\", \"name\": \"Why does this lockout specifically call out Siemens and \\\"shielded\\\" switches?\", \"acceptedAnswer\": { \"@type\": \"Answer\", \"text\": \"Many emergency stop buttons have a raised shield or guard ring around them to prevent accidental bumps, and Siemens switches in particular use a housing profile that a generic universal lockout cover often doesn't seat against cleanly.
