A finishing trim built for one job
The RT05 Screwless Window Trim is a dedicated face component for the RT05 recessed step light platform. It is not a standalone luminaire: it frames the opening in the wall and conceals the edge of the housing once the light engine is seated. Because there are no exposed screws or fasteners on the visible face, the finished result reads as a clean rectangle of light in the wall rather than a hardware-looking fixture. That matters most in the places where step lights live — narrow stairwells, hallway baseboards, entry risers — where every occupant walks past the trim at eye level or knee level several times a day.
Fit, cutout and finish
The RT05 system is designed around a rectangular opening with a hole cutout size of 4-3/4" × 2-7/8" (121 × 73 mm), and the RT05 step light measures L120 x W74 x H38 mm (L4 11/16 x W2 7/8 x H1 1/2"). Rough in the opening to that cutout, set the engine, then present the white trim to the face — the screwless retention holds it flat against the finished surface. White is one of three RT05 trim colours available in the family (black, brushed nickel, white), so you can standardize a whole project on one finish or mix by zone. Keep a spare trim on site during drywall touch-ups and painting: it's far easier to protect or swap a trim than to clean overspray off a light engine.
What the RT05 light engine brings
Paired with an RT05HV or RT05LV engine, the trim frames a light source rated at 145 lumens from 2W / 2.2W, available in 3000K warm white, 4000K natural white, RGB and RGBW, with a CRI >90 for true-looking wood, stone and carpet tones on stair treads. The platform runs at 100V AC or 12V AC/DC, is dimmable, carries an IP67 rating and an operating range of -20°C to +45°C, includes a 12" (30 cm) wire length, is c ETL us Listed and comes with a 3-year warranty. Those values belong to the RT05 light engine and housing; this SKU is the white trim that completes it.

Applications and documentation
Think basement stairs in a Montréal duplex, a hotel corridor where the overhead lights dim at night, a restaurant ramp, a condo lobby, an office stairwell that has to stay visible during an evacuation, or a covered deck stair where the IP67 engine can handle weather. In every case, the trim is what the client actually sees, so ordering it in the same family as the engine avoids mismatched openings and callbacks. For dimensions, cutout details and the full RT05 ordering information, consult the technical PDF (RT05 Screwless Step Light) in the Documentation tab before you cut your openings — confirming the cutout and the trim colour on paper takes a minute and saves a whole afternoon of patching.
