Safety Technology International STI-KIT-900-R – Frequently Asked Questions

1) What is the STI KIT-900-R spacer used for?
The KIT-900-R is a 2 inch red spacer that mounts behind an STI Stopper II cover to push it off the wall surface. It is used when the device needs extra depth, typically to clear a pull station, horn, or other surface-mounted device that sits proud of the wall. It fits the STI-4100 and STI-4130.
2) How much depth does the STI KIT-900-R add behind the cover?
Two inches. That is the spacer's stated size, and it is what you gain between the wall and the back of the STI-4100 or STI-4130 cover, so measure how far your pull station or device projects before deciding whether a 2 inch spacer gives you enough clearance.
3) Do I order the KIT-900-R separately from the STI-4100 stopper?
Yes. The spacer is a separate accessory, ordered on its own and added to an STI-4100 or STI-4130. If the device you are protecting sits flush to the wall, you do not need it at all; order it only when you need the extra 2 inches of standoff.
4) Is the KIT-900-R spacer red to match the Stopper cover?
Yes, it is supplied in red, which keeps it consistent with the red Stopper housings commonly used over fire alarm pull stations. For a facility standardizing appearance across openings, the red spacer reads as part of the device rather than an added shim.
