3' Extension Cord for Clone Bars

What It Is

The Matrix 3' Extension Cord is a factory-matched accessory cable designed to connect Matrix LED Clone, FR, and UV bar fixtures within a daisy-chained run. At three feet, it provides enough reach to bridge the gap between bars spaced across a standard propagation tray or multi-tier cloning rack without creating excess cable slack that becomes a management problem in a dense grow environment.

The cord uses the same connector spec as the Matrix bar ecosystem, meaning no adapters, no jury-rigged connections, and no risk of mismatched terminations disrupting a run of 20, 40, or 90 bars. It is purpose-built to work within the Matrix system — not a generic extension pressed into service.

Who Needs This

Any licensed operator running Matrix CB 18W clone bars, FR bars, or UV bars across a propagation or mother room will encounter spacing scenarios where the standard inter-fixture cord falls short. Vertical propagation racks with adjustable tiers, rolling clone benches, and wide-format trays all create gaps between bars that require a dedicated extension to maintain a clean, organized install.

This is also the correct part to reach for when retrofitting an existing clone room — adding more bars to an established run, adjusting bar spacing for a different tray pitch, or replacing a damaged cord mid-chain. Keeping a small stock of these on hand is standard practice for any commercial propagation operation running Matrix bar fixtures at scale.

Key Features

Plug-and-play design matches the Matrix bar connector standard — no wiring, no tools, secure locking connection. The cord is built to handle the high-humidity environment typical of propagation and cloning rooms, where condensation and misting cycles are a daily reality.

The 3-foot length is the critical spec here: long enough to bridge inter-bar gaps across a tray or rack section, short enough to route cleanly without creating the cable management issues that come with longer general-purpose extensions. For operators building out large daisy-chain runs — the Matrix CB system supports up to 90 bars at 277Vac — having the right-length inter-bar cord at every junction keeps the install professional and the electrical layout tight.

How It Fits a Build

In a typical commercial propagation build, Matrix clone bars are mounted under each shelf tier of a vertical rack system, daisy-chained in sequence. The 3' extension cord slots in wherever a standard cord's reach is insufficient — at the end of a tray, across a wider rack bay, or at the transition between two rack sections.

This cord is also relevant for FR and UV bar supplemental lighting runs in flowering or late-veg rooms, where bar-to-bar spacing across an undercanopy array may vary based on canopy width and rack configuration. One SKU covers Clone, FR, and UV bar applications across the Matrix bar line, simplifying the parts list for facilities running multiple bar types.
