Questions

Frequently Asked Questions

The SL600HD is an option for people who need more weight capacity than the standard SL600's 350-pound limit. It supports up to 600 pounds and may also suit someone who needs a wider seat or higher backrest.

It may. The SL600HD takes up more space when folded than the standard SL600, but folded width alone does not determine whether it will fit. The staircase also needs enough room for the rider to use the lift. Contact us to discuss your staircase and seating needs.

No. It is made for indoor staircases only.
