STUB UPS

STUB UPS, STANDARD CONFIGURATIONS

Quickly achieve horizontal-to-vertical direction changes with more precision and less formwork. RED-E-DUCT Stub-Ups save significant construction time while enhancing worker safety by reducing time spent in the trench. Construction teams can complete work faster, at a lower installed cost, compressing 30 days of work into as little as one day, compared to traditional conduit placement and concrete encasement.

Standard Sweep Radius: 36”
Conduit Types: RTRC Fiberglass, Rigid Metal, or PVC

Conduit Sizes: 4” or 6”
Joint Types: Varies with Configuration

Use stub-ups to quickly achieve horizontal-to-vertical direction changes.

Note: Extended base versions available in 2- and 3-row stub-ups. Joint and conduit types vary depending on project/application specifications.

Elbow Material Type

Various elbow materials are available for use in RED-E-DUCT stub-ups. Standard materials include, Polyvinyl Chloride (PVC), Rigid Galvanized Steel (RGS), or Reinforced Thermosetting Resin Conduit (RTRC)Fiberglass. Non-standard materials are available upon request.

Top Termination Options

The top termination of a RED-E-DUCT stub-up typically includes a coupling for interfacing with vertical conduits installed in a cast-in-place riser. Standard Top Termination options are shown below:

Elbow materials adhere to the following standards:
  1. For PVC conduits: NEMA TC-2, TC-6, TC-8 (Conduit), TC3 (Fittings), Federal Specification WC1094A, U.L. 651 Specifications, and shall be rated for use with 90° conductors in accordance with Article 352 of the latest National Electrical Code (NEC).
  2. For RTRC Fiberglass conduits: NEMA TC-14 Reinforced Thermosetting Resin Conduit (RTRC) Fiberglass and UL 2420 Standard for BG (BelowGround) Fiberglass conduit.
  3. For Rigid Metal Conduit: UL6 Standard for Safety Electrical Rigid Metal Conduit and ANSI1 Standard for Electrical Rigid Steel Conduit (ERSC).

Power Transmission & Distribution

Duct Bank Installation 

Installed in front of a bank entrance, RED-E-DUCT was used in
conjunction with cast-in-place duct bank to significantly reduce
construction time. Speed of installation reduced the impact to
local businesses.

Power Transmission & Distribution

Duct Bank Installation 

RED-E-DUCT Precast Duct Bank was utilized to reduce overall site construction time. A crew of four was able to install 60 feet of linear duct bank per hour. Horizontal and vertical runs were installed, including precast Stub-Ups containing rigid galvanized conduits.

Industrial Facility

Duct Bank for Fiber and Power Cable

RED-E-DUCT Precast Electrical Duct Bank was used to carry fiber and power cables serving a water treatment plant, significantly reducing the time and cost of installation.

Oil, Gas & Chemical

Duct Bank Infrastructure Under Access Roads   

RED-E-DUCT Precast Duct Banks were installed under and alongside site access roads in multiple locations. RED-E-DUCT became a perfect solution where site conditions required managing a high-water table and rapid installation, ensuring road closures and site disruptions were kept to a minimum.
