Features

Provides the same protection for your power supply cable as the straight-thru type AND…
Exits the cable flush against the panel, saving space and directing the cable parallel to the panel.
Overcomes space limitations and acts as a back or bottom bumper.
Corresponding Mounting Hole Plugs can be used to fill blank/unused Mounting Holes and thus allow for a single panel design for multiple applications.
Consult Heyco for other wire types and sizes.
