Abstract: A modular system comprising track-mounted fixtures and track is described. In some embodiments, fixtures access electrical power through electrified railings recessed within a relatively narrow power slot of the track. Primary mechanical support of the fixture weight is optionally provided from a magnetic mounting surface surrounding the power slot. The track cross-section optionally provides mounting surface area on mounting wings, allowing a narrower slot housing. Optionally, secondary mechanical support provided within the slot comprises a deployable anchoring element which laterally expands into a receiving area. Optionally, deployment comprises rotation of the anchoring element. The anchoring element, in some embodiments, acts as a secondary mechanical support, preventing, for example, accidental detachment of the fixture from the slot, without preventing repositioning movements of the fixture along the slot, even when fully deployed.
