Safety Technology International STI-9640 – Frequently Asked Questions

1) How do I know which size STI exit sign guard to order for my exit sign?
Measure the sign's face and its projection off the wall or ceiling, then pick the guard that clears it. Four sizes are offered: STI-9640 at 10.5 x 13.75 x 2.75 inches, STI-9740 at 15.5 x 20.5 x 6 inches, STI-9741 at 16 x 14.8 x 5.35 inches, and STI-9742 at 16 x 15.6 x 3.3 inches. Depth is the number people get wrong most often, so check the sign's projection against the 2.75, 3.3, 5.35 or 6 inch depth before ordering.
2) Is there a version of the STI exit sign damage stopper for a ceiling-hung exit sign?
Yes. Along with the standard wall-face guards, STI offers a ceiling mount configuration measuring 16 x 14.8 x 5.35 inches and a wall mount configuration at 16 x 15.6 x 3.3 inches. Pick the mount style that matches how the sign is hung, not just the size, because the mounting hardware geometry differs between them.
3) Can I mount an STI exit sign damage stopper outdoors or in a parking garage?
No. These guards are rated for indoor use only, even though the 9-gauge welded steel wire carries a corrosion-resistant polyester coating. For an exposed garage deck, loading dock or exterior wall, this is the wrong part.
4) Will a wire guard stop students from pulling exit signs off the wall in a school corridor?
That is what these are built for. The cage is 9-gauge welded steel wire, heavy enough to take impact from balls, carts and deliberate abuse, and it stands off the sign so a strike does not transfer straight into the housing. In a school or dorm corridor, pair it with the tamper-resistant screw kit (KIT-82 or KIT-19038) so the guard itself cannot be unscrewed.
5) Do the STI exit sign wire guards come with mounting hardware or do I have to supply it?
Mounting hardware is in the box. Each guard ships with clamps, anchors and screws. The only thing you may want to add is the tamper-resistant screw kit, KIT-82 or KIT-19038, which is sold separately.
6) If the exit sign battery or lamp fails, do I have to cut the guard off to service it?
No. The guard is designed to come off and go back on for service, so an MRO tech doing monthly and annual emergency lighting checks can pull it, test or swap the unit, and remount it. If you have installed tamperproof screws, keep the matching driver from KIT-82 or KIT-19038 on the service cart.
7) Can I standardize on one STI exit sign guard across a whole building?
Only if the signs and mounting arrangements match. Four configurations cover the range: two standard sizes (10.5 x 13.75 x 2.75 and 15.5 x 20.5 x 6 inches), a ceiling mount at 16 x 14.8 x 5.35, and a wall mount at 16 x 15.6 x 3.3. Buildings with a single sign model on a single mount style can run one part number everywhere; a mixed retrofit usually needs at least the standard plus the ceiling mount version.
