A generously padded seat
A full-sized backrest
A retractable seat belt for added security

This makes the SL600 an excellent option for narrow staircases commonly found in Indiana homes.

The Pinnacle SL600 uses Harmar’s helical worm gear drive system, paired with a reinforced nylon polymer gear rack. This advanced design provides a ride that is:
Exceptionally smooth
