Safety Technology International STI-9880 – Frequently Asked Questions

1) What size fluorescent fixture will an STI fluorescent light damage stopper cover?
The STI wire guards adjust to the fixture rather than coming in one fixed length. Three ranges cover most twin-tube layouts: the STI-9880 adjusts from 51 to 62.75 inches, the STI-101075 from 63 to 75 inches, and the STI-9881 from 74.75 to 98.25 inches. Measure the fixture housing first, then pick the range it falls into. A standard 4 foot strip lands in the 9880's range and an 8 foot fixture lands in the 9881's.
2) Can STI fluorescent light guards be installed outdoors or in a parking garage?
No. These guards are rated for indoor controlled environments only, so an open parking deck, a loading dock, or any exterior wall pack is outside what they are built for. The steel wire carries a corrosion-resistant polyester coating, but that coating is there for indoor durability, not weather exposure. Schools, warehouses, gyms, and public building corridors are the intended settings.
3) Do these guards fit any fluorescent fixture, or only twin-tube strips?
These are made for fluorescent twin-tube fixtures. If the fixture in your building is a lensed troffer, a high bay, or an LED panel, this is the wrong cage. The guard cradles the exposed strip housing and adjusts along its length, which is why the sizing is given as a length range instead of a length-by-width footprint.
4) I have a mix of 4 foot and 8 foot fluorescent fixtures in one building. Can I cover both?
Yes, with two different models. The STI-9880 spans 51 to 62.75 inches and handles the 4 foot fixtures, while the STI-9881 spans 74.75 to 98.25 inches for the 8 foot runs. The STI-101075 fills the 63 to 75 inch gap for odd-length housings. Order by measured housing length, not by nominal lamp size, since fixture housings run longer than the tube inside them.
5) Do I need to buy mounting hardware separately for STI fluorescent light stoppers?
Screws and anchors ship with the guard, so nothing extra is needed for a normal ceiling or wall mount. What you should confirm is the substrate: the included anchors suit typical indoor construction, and a concrete deck or unusual ceiling assembly may call for fasteners you already stock. The guards are built to come off and go back on, which matters when a tube needs changing.
6) Will a wire guard let me relamp without taking it down every time?
Relamping does mean removing the guard. STI built them for easy install and removal, and they mount with the supplied screws and anchors, so it is a hand-tool job rather than a demolition. The point of the guard is that you do it far less often, since the cage takes the ball, the bat, or the boom lift bump instead of the tube.
7) Are STI light stoppers strong enough for a school gym or a detention corridor?
The cage is welded heavy-duty steel wire with a corrosion-resistant polyester coating, which is the construction facilities use where vandalism and impact are routine. It is aimed squarely at schools, warehouses, and public buildings. Indoor use only, so an outdoor athletic structure is a different problem.
8) What colors do STI fluorescent light damage stoppers come in?
Finish follows the model rather than being a separate choice. The STI-9880 and STI-9881 are white, and the STI-101075 is black. If you are standardizing a corridor or a gym ceiling, that means the length range you need also sets the color, so a facility trying to keep one look across mixed fixture lengths should check the range list before committing.
