Safety Technology International STI-1280 – Frequently Asked Questions

1) What does the STI-1280 backplate actually do?
It's the mounting backplate for STI Stopper II and Weather Stopper covers. The plate gives the cover a flat, solid mounting surface against the wall so the cover seats and operates correctly over the device it is protecting. It is a part only, not a protective cover itself.
2) Will the STI-1280 backplate fit my Weather Stopper cover, or is it only for the indoor Stopper II?
Both. The 1280 is specified for Stopper II and Weather Stopper models, so it works behind either the indoor Stopper II or the outdoor/weatherproof version of the same family.
3) Do I need a backplate behind a Stopper II cover, or can I mount the cover straight to the wall?
You need the plate when the wall surface will not let the cover sit flat or seal, which is the common case on block, brick, textured or uneven substrates and over existing device backboxes. The 1280 gives the cover a true mounting surface so it closes and functions as intended. On a flat, sound surface where the cover mounts directly, the plate is optional.
4) What is the STI-1280 backplate made of, and will it hold up outdoors?
Polycarbonate, the same impact-resistant plastic used for the Stopper covers themselves. That is why it is the specified plate behind Weather Stopper covers in exterior and wash-down locations rather than a painted steel plate that would corrode.
5) I'm replacing a damaged backplate on an existing STI Stopper installation. Is this the right replacement part?
Yes, if the cover on the opening is a Stopper II or Weather Stopper. The 1280 is the service part for that family, so a cracked or missing plate behind one of those covers is replaced with this without touching the cover or the device underneath.
6) Is the STI-1280 a single part number, or do I have to pick a size?
One part, one configuration. The 1280 backplate is ordered as model STI-1280 with no size, color or finish choice to specify.
