Summit® Stairlift
Discover the Many Advantages of a Summit® Stairlift

Cost Considerations
In addition to the cost for the lift, be sure to consider the cost for installation, maintenance and repair. Many lifts require a two-person team, up to half-a-day to install, and you pay for it! Our lifts are so simple to install, it takes less than 2 hours.
The maintenance and repair costs for our lifts are also lower because we do not use expensive circuit
boards that are prone to failure.

The need for secure support is paramount. It’s why our armrests are extra rigid. It’s why our seats swivel exactly as they do. It’s why our back rest is adjustable. It’s why we use aircraft cable rated up to 4,200 lbs. on a drive system that has withstood the test of time for more than 50 years. It’s why safety sensors do not allow the lift to run unless the seat is in the proper position. It’s why our footrest has safety sensors to stop the lift if they encounter any obstacles on the stairs.

Our lifts are designed for fast, easy installation. The reason our lifts are so easy to install is because we do the hard part at the factory. The carriage is pre-installed on a short section of track. Installation is not much more complex than connecting a length of track, attaching it to the stairs, bolting down the seat, and plugging it in. Our installation instructions are clearly illustrated and very detailed, plus expert advice is never more than a phone call away.

Comfort and Convenience
The backrest has three different settings, and the fold-up footrest adjusts to two different heights for the utmost in custom comfort. The seat swivels 90° towards the landing at both top and bottom to address bending, balancing and twisting issues when transitioning to and from the lift. The spacious, wide seat features thick padding and attractive upholstery. The unit-control switch requires little manual dexterity to operate and is conveniently located at the end of the armrest.

Summit Power Options
Unlike other manufacturers, Summit Lifts provides you with the choice of two convenient power options. Choose between safe, AC electrical operation (low voltage, 24V controls), or add protection against power outages by using our DC battery operated system. Unlike other units, our DC battery operated unit continually recharges regardless of its position on the track. This eliminates the need for you to remember to park the lift on charging pins or to make sure it is in a charging zone.

Harmar stair lifts are designed to meet ANSI/ ASME A18.1 Performance Safety Standards when properly equipped.

All state and local compliance is the responsibility of the purchaser. Some states may require fees for site preparation and permits. The Pinnacle should only be installed by a certified, professional Harmar installer. If the stair lift is installed by any other means, the purchaser and installer assume responsibility for issues that may arise involving improper installation.
