Harmar Pinnacle SL300 Stair Lift

The Harmar Pinnacle SL300 is currently one of the best stair lift values on the market. The cost of the SL300 is comparable to the cost of lifts from foreign manufacturers. Yet it comes from Harmar, a United States manufacturer. The SL300 stairlift uses the same maintenance free helical worm gear drive as the SL600, which requires no grease. No grease means the rail does not attract dust, dirt, or pet hair. The SL300 stairlift takes up only 11″ of space when folded.

The 300 lb weight capacity of the SL300 is more than most stairlifts in the same price range. It also has many safety features, including a seat belt, swiveling seat, and footrest obstruction sensors. The swiveling seat allows you to enter and exit the stair lift while standing on the landing at the top of the steps. The footrest obstruction sensors stop the stairlift if an object is in the path of the lift. After the object is cleared, you can continue to use the lift.

The stairlift also comes with a set of remotes, giving you the ability to call/send the stair lift up and down the stairs without being on the lift. The remotes are especially helpful when there is more than one user in a home. They allow the user to ride down, then send the lift back so the second user can use the lift.

The Harmar Pinnacle SL300 is battery operated, and only needs to be plugged in to a regular wall socket to charge the batteries. The helical worm gear drive is more efficient than conventional rack and pinion systems, giving the SL300 up to 40 trips on battery power alone.

Additional Notes

The Pinnacle is the only stairlift on the market incorporating a helical worm gear drive. This drive system is a proven system. The Helical Nylon Polymer worm gear and gear rack used in the SL300 are the same parts used in the Pinnacle SL600HD Stair Lift. The SL600HD has an industry leading weight capacity of 600 lbs! The helical worm drive also gives the Harmar Pinnacle extended battery life. Due to the improved efficiency of a helical worm gear drive over a standard rack and pinon drive, you can get an industry leading 40 trips or more on battery power during a power outage. 

Harmar manufactures stair lifts and wheelchair lifts at their facilities in Lake Winnebago, MO and Sarasota, FL.
