Fiberglass Installation Made Easy
Everything you need to know, from tools to field bending to two-minute how-to videos, to make your next fiberglass conduit installation even easier.
Faster installation saves time and money
The NECA Labor Rates state that to install a 100-foot length of 6” diameter conduit takes just 9 hours for fiberglass conduit, compared to 24 hours for PVC SCH 40, 29 hours for PVC SCH 80, 30 hours for aluminum, 48 hours for galvanized rigid steel, and 60 hours for PVC-coated steel. Faster installation means safer, more cost-effective projects.
Saving time and money isn’t the only benefit fiberglass installation offers.
Fiberglass electrical conduit’s faster installation time contributes to lower overall project costs, while it’s light weight and versatile design make it easier to install than traditional rigid conduit systems.
The following recommendations must be verified by the contractor/installer and approved by the engineer of record. The information provided here is strictly for use as a guideline.
Conduit Application and Joint Guidelines
- Above Ground or Under Bridge: Use appropriate Champion Fiberglass RTRC for environment; epoxy adhesive/tight lock joint.
- Encased in Concreate (EB Quality): Champion Duct® Standard Wall with interference joint.
- Direct Buried (DB Quality): Champion Duct® Heavy Wall with gasketed or tight lock joint.
- High-Impact Areas: Champion Haz Duct® XW Type conduit.
How to make field cuts
Tools required for fiberglass installation include: fine-tooth hand-held hacksaw, portable band saw, chopsaw with diamond cutting blade, and an abrasive blade cutter.
Field Cutting Preparations 1-2-3
- Safety starts with fiberglass PPE. Field cutting personal protective equipment for working with fiberglass includes: long-sleeved clothing (long sleeve shirts), gloves, safety glasses, and particulate respirator.
- Mark the fiberglass conduit with a contrasting colored marker (cut line) before cutting with fiberglass cutting tools.
- Remove any cutting burrs or ridges with a 60-grit emery cloth before bonding.
How to make adhesive joint connections
- Put on your safety gear; you’ll need a metal spatula, adhesive gun, Champion Mix adhesive, mixing tip and 60-grit emery cloth.
- Insert adhesive in adhesive gun; expel adhesive until is an even color.
- Measure and mark reference points; add a minimum of 3” to each end of the conduit for installing couplings or termination fittings, then prepare for bonding by sanding with the emery cloth until the sheet in removed (for field-cut sections only). Sand the inside of the coupling.
- Apply the Champion Mix epoxy adhesive to the spigot end of the conduit and spread evenly with a metal spatula.
- Insert conduit section into fitting; allow adhesive to set before pulling cable.
How to field bend fiberglass conduit
- You will need an appropriately sized PVC hot box and a one-shot hydraulic conduit bender.
- Check NEC guidelines and Champion catalog for bending to radius and mark the center of the bend for reference.
- Heat the conduit in the PVC hotbox to 240°F (116°C). Rotate the conduit by hand, and, using an infrared thermometer, periodically check the temperature through the heating process.
- When the conduit reaches the appropriate temperature, place it in the bender and bend it in the desired radius.
- Once the elbow is bent, let it cool while still in the bender. Apply a cool wet rag or cool running water to speed the cooling if desired.
- Remove the elbow from bender after it cools.
Champion Fiberglass makes it easy to determine the number of joints and adhesive cartridges necessary for a project with our Epoxy Adhesive Calculator. Simply enter the conduit size, lengths, total feet to install, number of sockets and adhesive size specific to your project, then press submit to calculate an estimate. Visit the Epoxy Adhesive Calculator. […]
In 2016, our Haz Duct® XW Conduit was UL Listed for extended support spacing distances. Now, that UL Listing has grown to include expanded support spacing distances for our Standard, Medium (UL designates Champion Fiberglass MW for 5″ and 6″ as SW), and Heavy Wall fiberglass conduit. Support spacing distances for some diameters have doubled […]
Champion Fiberglass can easily be bent in the field with a PVC Hot Box. Additionally, due to its light weight, ease of cutting, and integral bell, fiberglass conduit is very easy to install.
The epoxy adhesive system makes the fiberglass joint as strong as the conduit itself. Another benefit of Champion Fiberglass’s epoxy adhesive system is in its three distinctive curing times, allowing you to choose the curing time that’s right for your job, ensuring you get the working time you need to make adjustments before the adhesive […]
It’s easy to compare labor savings for Champion Fiberglass conduit to other in-market materials. The NECA Manual of Labor Units allows you to compare the average installation rates (per 100-foot length of conduit) for several materials. From there, you can use your average hourly rate to figure savings vs. each material. Use the Champion Fiberglass […]
