Built for a clean, continuous runThe mini joiner is the straight, inline connector of the TUROLIGHT ASTELLA family. Its purpose is simple and mechanical: two track sections slide onto it, the set screws lock them in place, and the electrical path continues without interruption. Because it is a mini format, it keeps the two rails nose to nose so a 4 ft plus 4 ft run looks like a single 8 ft line on the ceiling rather than two pieces stuck together. The black finish matches black
track rails and blends into dark ceilings, exposed structures and matte-black hardware, while the same joiner can be used on white track when you simply need the mechanical and electrical link and the connection point isn't in a sight line.
Electrical and installation detailsThis is an
H-type, single-circuit component for a
120V, 60Hz, 20A system, Class I, rated
IP20 for dry indoor locations, with a 1-way (P + N + PE) configuration. The installation sequence from the instruction sheet is straightforward: shut the power off at the main panel before installing any track or accessory; mount the track sections first, using toggle bolts in drywall or plaster (5/8 mounting holes) or standard #10 wood screws on wood surfaces; then prepare the connector. Select the correct grounding tab — the tabs must be prepared before sliding the connector onto the NON-GROUND conductor side tab of the track section you are joining, and if the wrong tab has been removed, do not use the connector, because grounding will not be maintained. Loosen the set screws on the connector before sliding it into the open end of the track, align the polarity lines, then tighten the set screws. Finish by sliding dead-end caps into ALL remaining open ends of the track and tightening their set screws before energizing. Local installation requirements must be respected, and to reduce the risk of fire and electric shock, use only fixture assemblies marked for use with TUROLIGHT track.

Compatibility and how to plan your runThe joiner is part of a full accessory range built around the AST-TRK track: live-end and end feeds, X, L, T and straight connectors, floating connectors and dead ends all share the same H-type single-circuit profile. For the track itself, this connector joins the black sections —
AST Track 2 ft H type black,
AST Track 4 ft H type black,
AST Track 6 ft H type black — and the white sections such as
AST Track 12 ft H type white. A good rule when you spec: measure the total run you want, choose the fewest track lengths that add up to it, and order one mini joiner for every junction between two sections. Track heads and lampholders install on the rail afterwards by aligning the polarity lines, pushing the adapter into the slot and turning 90°; if the adapter doesn't turn easily, don't force it — turn the other way.
Where it earns its keepRetail is the classic case: a long merchandising wall or a row of display tables needs an uninterrupted line of
track light heads, and a single stock length rarely covers it. At home, it's the kitchen-to-dining run, a hallway with artwork, a finished basement or a loft with exposed beams. In commercial spaces — cafés, salons, clinics, showrooms, offices and small galleries across Canada — joined runs let you re-aim and add fixtures later without touching the ceiling again, which is a real advantage when a layout changes with the seasons. The installation instruction sheet for the ASTELLA H-type single-circuit system (applicable to AST-TRK models) is available as a PDF in the Documentation tab of this page, in English and in French. Add the mini joiners to your order with your track and build the continuous
track lighting layout your project deserves.
