Used Handicare 1100 Stairlift. This is a slide track unit that means that the the rail itself actually climbs slowly up on the brackets as the chair goes up. This option eliminates tripping issues at the bottom of the stairs. This option is a more expensive one. This is like new and was only used for a few months. New this was $9700.00 after installation and taxes. The chair it self is worth the most. The rails are 102 inches long, you might be able to buy more at any length( I didn't look into that)? It looks quite easy to install. Product Highlights: - Weight limit: 308 lbs - Continuous charge strip - Foldup seat, footrest and armrests save space for other stair users - Safety sensors immediately stop the lift if anything is detected in its path - Manual swivel seat for safer transfer onto and off of the lift - Move silently and gently with a soft start/stop - Key switch prevents unauthorized use - Manual emergency stop - Two remote controls included - Retractable seat belt included - Battery back-up in the event of power outage - Four drive motors allow for completion of trip in case of single motor failure
