Arlington Industries 4001 – Frequently Asked Questions

1) What trade sizes do Arlington throat liners come in?
Arlington's non-metallic adjustable throat liners are made in five trade sizes: 1/2 inch (part 4001), 3/4 inch (4002), 1 inch (4003), 1-1/4 inch (4004) and 1-1/2 inch (4005). Match the liner to the trade size of the fitting or knockout it is going into, not to the wire size.
2) Are Arlington non-metallic throat liners UL listed for a permitted installation?
UL Listed, yes. That is the box an inspector or a spec-driven MRO buyer looks for on an insulating throat component, and it applies across all five trade sizes of the gray Arlington liner.
3) I ordered a 3/4 inch connector by mistake, will the 1/2 inch Arlington liner work in it?
No. The liners are sized per trade size, and the 1/2 inch (4001) is cut for a 1/2 inch throat. For a 3/4 inch fitting order the 4002. Sizing them by the fitting is the whole point, an undersized liner will not seat and an oversized one will not go in.
4) What does a throat liner actually do in a conduit fitting?
It lines the throat of the fitting so conductors bear on smooth plastic instead of a metal edge as they are pulled through. The Arlington liner is non-metallic, so it also puts an insulating barrier between the conductor insulation and the metal fitting at the point where pulling tension is highest.
5) Do I need throat liners if my fittings are already insulated throat?
No, an insulated throat connector already carries the bushing surface built in. These Arlington liners are for the fittings and knockouts that do not have one, or where the original insulating throat has been damaged or removed. Buying both for the same fitting is duplicate spend.
6) Will a plastic throat liner corrode in a damp mechanical room or exterior pull point?
The liner is non-metallic, so it will not rust or corrode the way a steel insert would, and it does not create a dissimilar metal contact inside the fitting. Note it is an insulating liner, not a seal, so it does not make the connection watertight on its own.
7) Can I standardize one part across a building's conduit runs, or do I need every size?
Stock by the trade sizes actually on the job. Most branch circuit work lands on 1/2 inch (4001) and 3/4 inch (4002); feeders and larger raceway runs take the 1 inch (4003), 1-1/4 inch (4004) and 1-1/2 inch (4005). All five are the same gray non-metallic liner, so the only variable to track is the size.
