That planning step matters for contractors, facilities teams, low-voltage installers, and hands-on buyers alike. A compatible conduit-and-connector set helps avoid the common last-minute problem of having the right coil but the wrong fitting at the termination point.
When a cable route needs more flexibility than a straight pathway allows, 3/4-inch Greenfield flexible metallic aluminum conduit can be a practical component to evaluate. Before adding material to a cart, however, the productive question is not simply, “Do I need Greenfield?” It is: Does the conduit size, run length, connection orientation, and project specification all line up?
Sky High Supply Company offers a 3/4-inch Greenfield flexible metallic aluminum conduit, UL listed, in a 100-foot coil. It is paired on the store with both a matching 3/4-inch straight metallic squeeze connector and a 3/4-inch 90° metallic squeeze connector. Together, these three listings give buyers a straightforward starting point for planning a 3/4-inch flexible metallic conduit run.
What is 3/4-inch Greenfield flexible metallic conduit?
“Greenfield” is a commonly used name for flexible metallic conduit. In practical terms, it is a flexible metallic raceway option used where a route needs to negotiate equipment connections, obstructions, or changes in direction that are less convenient for a rigid straight run.
The Sky High Supply product is specifically described as:
•3/4-inch flexible metallic aluminum conduit
•Supplied as a 100-foot coil
•UL listed
Those are important product facts, but they are not the entire installation decision. Conduit selection should also reflect the project’s drawings, cable requirements, environment, termination method, local code requirements, and the authority having jurisdiction. A product listing cannot determine whether a particular installation is compliant or appropriate.
Why the matching connector is part of the purchase, not an afterthought
A conduit coil is only one part of the assembly. At each point where the run terminates, enters an enclosure, or connects into equipment, the fitting must match the conduit size and the physical direction of the layout.For this product family, the two available connector styles answer two different routing needs:
| Layout need | Connector to evaluate | What to confirm before ordering |
| A direct, inline connection | 3/4-inch Greenfield straight metallic squeeze connector | Confirm that the 3/4-inch conduit size and straight orientation suit the entry point. |
| An angled change at the connection point | 3/4-inch Greenfield 90° metallic squeeze connector | Confirm that the 3/4-inch conduit size and 90° orientation fit the layout and available clearance. |
Both 3/4-Inch Greenfield connector listings are described as metallic, squeeze type, and UL listed. The difference is orientation, not a reason to assume one fitting is universally better than the other. A straight fitting is appropriate to evaluate when the run approaches in line with the connection. A 90° fitting is appropriate to evaluate when the path needs an angled approach.
A practical pre-order checklist for a 3/4-inch Greenfield run
A few minutes of planning can reduce returns, rework, and jobsite delays. Before ordering, confirm the following:
1.Conduit size: Verify that the specified or existing flexible metallic conduit is 3/4 inch. Do not select a connector by appearance alone.
2.Total route length: Measure the planned route and account for the required run length before choosing a 100-foot coil. Consider your project’s cut allowance and material-handling practices.
3.Termination count: Identify every place the conduit will need to connect. Each connection point may require a compatible fitting.
4.Connector direction: Decide whether every termination needs a straight approach or whether one or more locations need a 90° approach.
5.Clearance around equipment: Check where the conduit will enter. A fitting that works on a drawing can still create an awkward approach in a tight enclosure or equipment area.
6.Project and safety requirements: Confirm the full installation requirements with the project documents, applicable code, manufacturer instructions, and the authority having jurisdiction.
Build the correct component set
For a 3/4-inch Greenfield flexible metallic conduit order, start with the product that defines the run, then add the fitting style that matches each connection point:
•For the run:3/4-inch Greenfield Flexible Metallic Aluminum Conduit, UL Listed, 100-foot coil
•For straight entries: 3/4-inch Greenfield Straight Metallic Squeeze Connector, UL Listed
•For angled entries: 3/4-inch Greenfield 90° Metallic Squeeze Connector, UL Listed
Frequently asked questions
Is this 3/4-inch Greenfield conduit sold by the foot?
The Sky High Supply listing is for a 100-foot coil of 3/4-inch flexible metallic aluminum conduit. Confirm the product page at the time of purchase for current availability and product details.
Which connector fits the 3/4-inch Greenfield flexible conduit?
Sky High Supply lists a 3/4-inch Greenfield straight metallic squeeze connector and a 3/4-inch Greenfield 90° metallic squeeze connector for 3/4-inch Greenfield flexible conduit. Select the orientation that matches the planned connection, and verify all compatibility and installation requirements before ordering.
When should I choose a straight connector versus a 90° connector?
Evaluate a straight connector when the conduit approaches the connection in line. Evaluate a 90° connector when the connection requires an angled approach. The correct selection depends on the physical layout, clearance, project documents, and installation requirements.
Is the conduit UL listed?
Yes. The live product listing identifies the 3/4-inch Greenfield flexible metallic aluminum conduit as UL listed. The matching straight and 90° squeeze connector listings are also identified as UL listed.
