Pinnacle Stairlift

$3,200.00

The Harmar SL300 Pinnacle Straight Stairlift is probably one of the best values when it comes to entry level stairlifts. With a capable 300 lb. weight capacity, it features a slim profile, attractive design and incorporates the same worm-gear drive system design utilized by Harmar’s other Pinnacle stairlifts, the SL600 Pinnacle Premium and the SL600HD Pinnacle HD. What makes the patented worm-gear drive unique is that it requires no lubrication, making this a low-maintenance unit capable of running for years and is especially desirable in homes where pets or children are present due to the lack of necessary regular lubrication intervals used by traditional rack-and-pinion stairlift designs.

The SL300 and SL600 stairlifts are available with optional Pinnacle folding rail for customers needing to clear walkways.
