    Safety Technology International STI-EM07123.5 – Frequently Asked Questions

    1) Can an STI metal protective cabinet be used outdoors or in a washdown area?
    No. The STI Metal Protective Cabinet is a Type 1 enclosure, which is indoor use only. It is UL and cUL Listed as an industrial control panel enclosure for indoor service, so it protects equipment from accidental or intentional damage and contact, not from rain, sprinkler water, or hose-down. For an exterior wall, a dock, or anywhere it can get wet, you need an outdoor-rated enclosure instead.
    2) What size STI protective cabinets are available and how many come in a box?
    Six sizes, each sold in a fixed multiple: 8.40 x 7.66 x 3.80 inches in packs of 8, 11.20 x 11.28 x 3.30 inches in packs of 4, 12.20 x 7.73 x 3.84 inches in packs of 6, 12.20 x 12.7 x 4.30 inches in packs of 4, 15.20 x 11.28 x 4.30 inches in packs of 4, and 18.20 x 15.28 x 4.30 inches in packs of 2. If you are covering one panel, you still buy the full multiple, so size the order against how many openings or panels you are protecting across the building.
    3) Does the STI protective cabinet come with a lock?
    No lock is included. The lock is a separate order, and there are two choices: the KL544 key lock, which ships with 2 keys, or the TL644 thumb lock. Pick the key lock where only authorized staff should get in, such as a tenant corridor or a public area, and the thumb lock where you just want the door held shut and staff need quick hands-on access. Spare keys for the KL544 are available as KIT-H18086.
    4) Will an STI protective cabinet mount flat on a block or brick wall that is not perfectly true?
    Yes. The back of the cabinet is designed to accommodate uneven walls and surfaces, so it wall mounts directly on block, brick, or an out-of-plumb surface without needing to be shimmed square. If you need to hold it off the wall entirely, for example to clear conduit or an existing device box behind it, the KIT-H18019 standoff kit does that.
    5) Where does conduit enter an STI metal protective cabinet?
    Through knockouts in 1/2 inch and 3/4 inch sizes, located on the top, sides, and bottom. That gives you a run in from above for a surface conduit drop, from below for a feed out of the floor or wall base, or from either side when you are tying into an adjacent box, without drilling the enclosure.
    6) How well does an STI protective cabinet hold up to daily use in a corridor or plant floor?
    The cabinet is powder-coated metal, which resists corrosion, and the door swings on a continuous piano-type hinge rather than a pair of leaf hinges, so the load spreads down the full height of the door instead of concentrating at two points. That is the detail that matters in a hallway or shop where a cabinet gets opened repeatedly and occasionally leaned on. Body steel is 17 or 18 gauge depending on the size.
    7) Is there anywhere to keep the panel schedule or inspection log with the STI cabinet?
    Yes, a document holder is built in, with a pen and key attachment. For an MRO or facilities crew that means the wiring diagram, panel schedule, or last inspection record lives at the equipment instead of in a binder in the shop, and the spare key can hang with it.
    8) Can I get STI protective cabinets labeled for a specific building or system?
    Custom printing is available on request, so a cabinet can be marked for the system it covers, for example a specific panel, tenant, or department. That is worth doing when you are standardizing a run of identical cabinets across a facility and crews need to tell them apart at a glance.
