A small part that protects a whole installationAn open track end is an exposed conductor waiting for a problem. The
AST-TRK-H-EC-BK dead-end cap plugs that opening on the ASTELLA
H-type single circuit track, keeping fingers, dust and debris out of the copper channel. In the TUROLIGHT installation sheet it sits alongside the other system connectors — AST-TRK-H-LEC live end feed, AST-TRK-H-SC, AST-TRK-H-LC, AST-TRK-H-TC, AST-TRK-H-XC, AST-TRK-H-FC and AST-TRK-H-MJ — and it carries the same black finish as the black track sections, so the end of the run reads as one clean line instead of a raw cut.

Electrical and installation detailsAlways start by shutting off the main supply at the panel before touching track or accessories. Before sliding any connector into the track, loosen the set screws; the instructions insist on this for every connector type. The dead-end cap then slides into the open end of the track and is locked with its set screw. The same sheet reminds installers of the polarity rule for the system: the grounding tabs on connectors must be prepared before sliding onto the NON-GROUND conductor-side tab of the track section being joined, and a connector whose wrong tab has been removed must not be used, because grounding would no longer be maintained. Local installation requirements must be respected, and to reduce the risk of fire, every open end of the completed run must receive a dead-end fitting with its set screw tightened before power is restored.
Compatibility across the ASTELLA familyThis cap is dedicated to the
H-type single circuit track — it is not a universal part, and the safety notice is explicit that only fixture assemblies marked for use with this track should be installed on it. Use it to terminate runs assembled from the
AST Track 2 ft black,
AST Track 4 ft black and
AST Track 6 ft black sections, or from the white family including the
AST Track 12 ft white when a longer run is planned. Heads are mounted by aligning the polarity lines of the track and the lampholder, pushing the top of the adapter with its contact tabs into the track slot and turning 90°; if it does not turn easily, turn the other way rather than forcing it, and press the release lever to remove.
Where it earns its place, and documentationThink of every project where
track lighting runs stop at a wall, a bulkhead or mid-ceiling: a boutique wall of merchandise, a gallery picture wall, a café counter, a hair salon, an office reception, a showroom, or a home kitchen island and hallway. Each open end needs one cap, so count your terminations at quoting time and avoid a second trip. The technical PDF (AST-TRK-H-EC-BK Spec Sheet) with the full bilingual installation instructions is available in the Documentation tab of this page for your electrician or your permit file.
