What this connector actually doesA track run is only as long as the pieces you can link together. The
AST TRACK - STRAIGHT CONNECTOR - H TYPE - 1 CIRCUIT - BLACK is an inline joiner: it enters the open end of one track section and the open end of the next, carrying the conductors straight through so both lengths behave as one continuous circuit. That means one feed, one switch, and heads that can slide anywhere along the whole run. It belongs to the ASTELLA track system from TUROLIGHT and is part of the same accessory family as the end connectors, L connectors, T connectors, X connectors and mounting accessories listed for AST-TRK-H hardware.

Installation, polarity and safetyStart by shutting off the power at the main panel (fuse or breaker box) before installing any track or accessory. Loosen the set screws on the connector before sliding it into the open end of the track — forcing it in with the screws tight is the most common cause of a bad joint. To maintain circuit polarity, the ground tabs on the connector must be prepared before sliding it onto the NON-GROUND conductor-side tab of the track section you are joining; if the wrong tab has been removed, do not use the connector, because grounding will not be maintained. For wire connections, cut and strip the wires from the box (3/8" strip) and secure them to the screw terminals in the connectors or live end feeds. Once all track and connectors are in place, make sure dead-end caps are slid into ALL open ends of the track and that the set screws are tightened before power is restored. To reduce the risk of fire and electric shock, use only fixture assemblies marked for use with TUROLIGHT track, and always follow basic safety precautions and local installation requirements.
Compatibility and how heads attachThis connector is made for H-type, single circuit ASTELLA track and is not interchangeable with other track profiles. Lampholders mount the usual way: align the polarity line of the track with the polarity line of the lampholder, push the top of the mounting adapter (with the contact tabs) into the track slot and turn 90°. If the adapter does not turn easily, don't force it — turn the other way. To remove a head, press the release lever with your index finger and turn 90°. Pair this connector with the black ASTELLA track lengths —
AST Track 2 ft,
AST Track 4 ft,
AST Track 6 ft — or with the white versions such as the
AST Track 8 ft H type 1 circuit white when the ceiling is light and the track has to disappear.
Real projects and documentationPicture a long galley kitchen where a single track section stops short of the sink: one straight connector and a second section carry the line right to the end wall. Same story in a boutique where the display wall keeps growing, in a basement rec room, in a hair salon that needs even light at every chair, or in a small gallery where every canvas deserves its own adjustable head. Because the run stays on one circuit, the whole line still turns on with a single switch, and heads can be repositioned any time the layout changes. The full installation instruction sheet for the AST-TRK H-type single circuit system, in English and French, is available in the Documentation tab of this page — read it before you start, and keep it with your project file.
