Widely available at most hardware stores.
Flexible design allows gradual bends without specialty couplers.
Offers good protection from low level vandalism, weather (rain, hot/cold conditions and UV exposure), wildlife, and accidental damage.
Easier to cut and form than EMT (Electric Metallic Tube) and Flexible Metal Conduit (FMC) conduit.
Cable is able to be pulled through in most cases.
High Cost: 100ft roll costs between $60 - 250
Larger outside diameter than EMT (more unsightly)
Can be easily cut (vandalism).
Will still require adaptors for tight bends.
Less options with couplers and adaptors than EMT.
Difficult to make right angles and straight lines (more unsightly).
When to use Liquidtight Plastic Tubing
One or two hole strap fitted to the size of conduit you are using
Fasteners for the surface you are mounting to
Step by Step Installation Instructions
Measure to length and cut conduit using PVC cutter, overcompensate for any unexpected bends you can cut more off later.
Run cable through conduit
