Built for one job, done right
The RT05 Louver Trim is not a universal ring you force into place — it is the dedicated faceplate for the RT05 light engine series. That single-purpose design is what makes the install fast: the trim indexes to the RT05 aperture, sits flush and keeps the engine's optical pattern intact. The louver trim style is recognized across the lighting industry for glare control, and that is its whole reason for being on a low-mounted fixture. The stepped internal baffles cut the high-angle light that causes discomfort at eye level and push the output down where it belongs, onto the tread, the floor or the path.
Finish and appearance
This SKU ships in white. On painted gypsum, white risers, pale millwork or light stone, it reads as a quiet detail rather than a fixture — which is usually the point with a recessed step light. The RT05 platform offers trims in black, brushed nickel and white, so a designer can mix finishes room by room while keeping the same engine behind the wall. If a trim gets damaged on site, or a client changes the wall colour later, the trim can be swapped on its own.

Compatibility and installation
Use this trim with the RT05HV (high voltage) or RT05LV (low voltage) light engine — those are the two products it was designed around. The RT05 rough opening is 4-3/4" × 2-7/8" (121 × 73 mm), so if your cutout was made for the RT05, this trim will cover it correctly. Install the engine and wiring first, verify the fixture is powered and aimed as intended, then set the trim last so it does not collect drywall dust or paint overspray. On a jobsite, a smart habit is to order a few spare trims with the engines: painters and finishers are hard on faceplates, and having a matching white trim on hand at punch-list time saves a return trip.
Where it earns its keep, and documentation
Think hotel corridors and stair cores, condo and apartment common areas, restaurant banquette bases, theatre aisles, retail showroom plinths, office circulation and home basement staircases. Anywhere occupants walk past a light at shin height, a louvered faceplate is the difference between guidance lighting and an annoying bright spot. Contractors, lighting designers and facility managers standardizing on the RT05 platform can keep this trim in stock for retrofits and replacements without specifying a whole new fixture. The RT05 screwless step light technical PDF is available in the Documentation tab of this page for cutout dimensions and engine details.
