Product Details
Designed for straight staircases, the SL600 supports up to 350 lbs while folding to just 10.5 inches from the wall. This slim profile helps leave more room on the staircase for family members and guests when the lift isn't being used.
The Pinnacle SL600 also features Harmar's patented nylon polymer gear rack and helical worm gear drive system, providing a smooth, quiet ride without the grease and lubrication required by many traditional stair lift systems.

One of Harmar's Most Compact Stair Lifts
One of the standout features of the Pinnacle SL600 is its compact design.
With the seat and footrest folded, the SL600 measures only 10.5 inches from the wall, making it an excellent choice for homes where maintaining usable staircase width is important.
Even with the optional folding rail, the folded width is approximately 13⅝ inches.
Comfortable 350 lb Capacity
The SL600 provides a 350 lb weight capacity along with a larger seat than Harmar's more compact SL300.
The seat measures 18" wide, providing comfortable everyday seating without the additional size and bulk of a heavy-duty stair lift.
For users requiring substantially more room or capacity, the Harmar SL600HD offers a 600 lb capacity.
No Grease, No Mess
The Pinnacle SL600 uses a patented nylon polymer gear rack and helical worm gear drive system.
Unlike stair lifts that require grease or lubrication along the rail, the SL600's system is designed to operate without it. That means less mess around your staircase, clothing, children, and pets, while also reducing routine maintenance.
The drive system is also engineered to provide smooth and quiet operation.
Works During a Power Outage
A power outage doesn't necessarily mean losing access to your stairs.
The SL600's efficient battery-powered system can provide up to 60 trips during a power outage, helping you maintain access between floors until household power is restored.
Built-In Safety Features
The Harmar Pinnacle SL600 includes several safety features for everyday use:
- Retractable seat belt
- Overspeed brake
- LED alert system
- Swivel seat with safety interlock
- Footrest obstruction sensor
- Chassis obstruction sensor
- Padded armrests
If the lift encounters an obstruction while traveling, its obstruction sensors are designed to stop the unit.
Optional Automatic Folding Rail
If the bottom of your staircase ends near a doorway, hallway, or walkway, the optional automatic folding rail can help keep the lower landing clear.
The folding rail moves out of the way when the stair lift isn't in use, helping reduce potential trip hazards and keeping frequently used areas more accessible.
Available Options
The SL600 can be customized with several available options:
- Automatic folding rail
- Key lock
- Additional rail
- Manual lowering tool
The folding rail is especially helpful when the bottom of the stair lift rail would otherwise extend into a doorway or frequently used walkway.
SL300 vs. SL600 vs. SL600HD
Choosing the right Harmar Pinnacle stair lift depends on the user's size, comfort requirements, staircase, and weight capacity.
The SL300 is a compact choice for users who need up to 300 lbs of capacity. The SL600 steps up to 350 lbs and offers a larger seat with premium comfort features while maintaining an exceptionally narrow folded profile. For users requiring significantly more capacity and seating room, the SL600HD supports up to 600 lbs.
For many customers who want a premium straight stair lift without moving into a heavy-duty model, the SL600 offers an excellent balance of comfort, capacity, and compact design.
Professional Stair Lift Installation
Proper measurements are important before purchasing any stair lift. Staircase length, angle, width, landing space, user weight, transfer requirements, and nearby doors or walkways should all be considered.
Our mobility experts can help determine whether the Harmar Pinnacle SL600 is the right stair lift for your home and help you choose the proper track length and available options.
