Topaz Lighting Flexible Aluminum Conduit, 250' Coil

Topaz Lighting's Flexible Aluminum Conduit is a lightweight, corrosion-resistant raceway solution designed for electrical installations in tight spaces and complex routing applications. Fabricated from a corrosion-resistant aluminum alloy and tempered for additional strength, this conduit is available in a convenient 250' coil and in trade sizes ranging from 3/8" to 4". The smooth interior bore allows for easy wire pull-through, and at one-third the weight of steel conduit, it is significantly easier to handle, cut, and transport on the job site. UL Listed for code-compliant installations.

Key Features

Topaz Lighting 4-300 – Frequently Asked Questions

1) What trade size is the Topaz 4-300 flexible aluminum conduit coil?
Model 4-300 is the 3/8 inch trade size, supplied as a 250 foot coil. Topaz builds this flexible aluminum conduit across trade sizes from 3/8 inch up to 4 inch, so if you are running larger feeders you want a different size in the family, but 3/8 inch is the one that covers fixture whips, small equipment drops and tight fishing work.
2) What connectors do I need to order with this flexible aluminum conduit?
The conduit ships as coil only, so connectors and clamps are a separate line on the order. Topaz makes a full line of flexible conduit connectors and clamps intended to pair with it, and you size them to the trade size you are running, 3/8 inch for model 4-300. Count your boxes and terminations before you order so you are not short a fitting at trim-out.
3) Is this flexible aluminum conduit liquidtight?
No. It is standard flexible metal conduit in aluminum alloy, not a liquidtight product, so it has no outer PVC jacket and is not intended for wet or washdown locations. For outdoor, damp or oil-exposed terminations you want a liquidtight flexible metal conduit with a jacketed construction and sealing liquidtight connectors instead.
4) Is Topaz flexible aluminum conduit the same as regular steel flex, and when should I use aluminum instead?
Both are flexible metal conduit (FMC), but the Topaz product is fabricated from a corrosion-resistant aluminum alloy that is tempered for added strength, and it runs about one third the weight of steel conduit. That matters on long overhead runs and on jobs where you are hauling a lot of coil. Where corrosion is a concern, the aluminum alloy is the reason to pick it. Steel flex is still the choice where you need the mechanical toughness of steel in an exposed, high-abuse location.
5) Can this be used where rigid conduit will not route, like tight bends behind equipment?
That is what it is built for. The flexible aluminum conduit is made for routing through small spaces and tight bends where rigid cannot go, and it is also used on equipment connections and motor terminations where you want some vibration isolation between the raceway and the machine.
6) Will 250 feet of 3/8 inch flex be enough for a floor of light fixture whips?
A 250 foot coil goes a long way at 3/8 inch because whips are typically short runs, and buying it by the coil rather than in cut pieces cuts down on splices. For a fixture-per-room layout, estimate your average whip length, multiply by fixture count, and add slack for bends and terminations. Larger equipment feeds will eat the coil much faster.
7) Will wire pull easily through this conduit on a long run?
The bore is smooth on the inside, which is the point of it for pulling. Less friction on the jacket means a cleaner pull and less pulling tension on the conductors. On long or multi-bend runs still use pulling lube and keep your total bend degrees reasonable.
