Harmar Pinnacle SL300 Straight Stairlift

The Pinnacle SL300 provides seated access on a straight staircase for users up to 300 lb. Harmar specifies a travel speed of 20 feet per minute and reports up to 60 up-and-down cycles on battery power during a power outage. The battery backup allows operation when household power is unavailable; actual availability depends on the lift's battery condition and charge.

Space-conscious rail and drive

The SL300 uses a nylon-polymer gear rack and helical worm-gear drive, and Harmar says it requires no grease or lubrication. When folded, the rail can sit close to the wall with the seat and footrest raised to reduce obstruction on the stairs. Measure the full staircase, landings, doorways and transfer area before ordering; a site assessment is needed to confirm the rail layout and clearances for your home.

Build and safety options

Harmar lists a seat belt, overspeed brake, audible alert, swivel-seat interlock and footrest obstruction sensor. Power seat swivel, power footrest, automatic folding rail, chassis obstruction sensor and other options depend on the configured build; confirm the selected equipment and rail length on your quote. Use the stairlift only as directed in the owner manual and keep the route clear.
