SEPCO 4F Malleable Iron Floor Flange, 4-Hole Threaded Insert, 1-1/4-Inch

The SEPCO 4F Floor Flange is a malleable iron, 4-hole threaded insert flange designed for 1-1/4-Inch pipe or conduit. It provides a secure, permanent mounting point for anchoring vertical pipe, conduit risers, rods, or posts to a floor, base plate, or other flat structural surface. The four-hole bolt pattern allows installers to anchor the flange with lag bolts or masonry anchors for a stable, load-bearing connection, and the malleable iron construction delivers the strength needed for demanding commercial and industrial settings. The 1-1/4-Inch threaded insert accepts standard 1-1/4-Inch pipe threads for a solid, vibration-resistant mechanical joint, making the 4F a practical choice anywhere a fixed vertical run needs a dependable floor-level anchor point.

Key Features

  • Trade Size: 1-1/4-Inch threaded insert sized to accept 1-1/4-Inch pipe or conduit.
  • Durable Construction: Malleable Iron body provides the strength and impact resistance needed for demanding commercial and industrial installations.
  • 4-Hole Threaded Insert: Threads onto 1-1/4-Inch pipe and bolts down through four mounting holes for a secure floor or base-plate connection.
  • Mounting Pattern: Four bolt holes allow secure anchoring to floors, base plates, or other flat structural surfaces using lag bolts or masonry anchors.
  • Versatile Compatibility: The 1-1/4-Inch threaded insert works with standard threaded pipe, conduit, or rod for use across a range of trades.
  • Simplified Installation: The pre-threaded insert allows the flange to be threaded directly onto 1-1/4-Inch pipe without additional couplings, while the 4-hole pattern speeds anchor installation.
  • Application: Provides a stable, permanent anchor point for vertical pipe, conduit, or posts at floor level.

SEPCO 4F – Frequently Asked Questions

1) Will the SEPCO 4F floor flange thread onto 1-1/4 inch rigid conduit?
Yes. The 4F has a 1-1/4 inch threaded insert that takes standard 1-1/4 inch pipe threads, so threaded rigid conduit, pipe, or threaded rod of that trade size screws straight in. No coupling or adapter is needed between the flange and the riser.
2) What fasteners do I need to anchor a 4-hole floor flange to a concrete floor?
The 4F ships as the flange only. You supply the anchors: four lag bolts into wood or structural base plate, or masonry anchors into concrete, one through each of the four mounting holes. Pick the anchor for the substrate and the load the riser will carry.
3) Does the SEPCO 4F floor flange come in other sizes besides 1-1/4 inch?
The 4F is a single-size part, model 4F, built for 1-1/4 inch. If your riser is a different trade size you need a different flange; threading a 1-1/4 inch insert onto anything else is not an option.
4) Is a malleable iron floor flange strong enough for an industrial floor-mounted post?
Malleable iron is the body material on the 4F, chosen for strength and impact resistance in commercial and industrial work. Combined with the four-bolt pattern it gives a load-bearing anchor for vertical pipe, conduit risers, posts, or rod at floor level.
5) Can I use the SEPCO 4F to base-mount a pole or post, not just conduit?
Yes, as long as the item threads in at 1-1/4 inch. The 4F is used for conduit and pipe riser mounting, post and pole base anchoring, rod and support anchoring, and base plate connections. It is the thread size, not the trade, that decides fit.
6) Can the 4F flange be mounted to a steel base plate instead of the floor?
It can. The four-hole pattern bolts down to any flat structural surface, floor slab or base plate alike, which is how it is commonly used to land a vertical run on fabricated steel rather than concrete. Drill and tap or through-bolt the plate to suit.
7) What is the exact part number to order for the SEPCO 1-1/4 inch 4-hole floor flange?
Order SEPCO model 4F. One configuration only: malleable iron, 4-hole, 1-1/4 inch threaded insert, so there are no finish or size suffixes to specify.
