What are dart profiles?
The most commonly used profile is the dart profile also known as the arrow head profile. This profile type has a dart (arrow head) with “teeth” that hooks into the slot when it is pushed in firmly.
Most of our dart type profiles have a magnet chamber, which can hold a magnetic strip.
DSU profile codes with an –M extension have a magnet chamber. Dart profiles in our assortment that do not have a magnet chamber have a profile code with the extension –A or –R.
