Product information

Overview

Delta is a platform stairlift for straight staircases. It is designed to carry a wheelchair user on its platform and can also be configured with an optional folding seat, subject to the selected specification and site assessment.

The rail can be fixed to the wall or supported on posts. When folded, the platform occupies 300 mm from the wall, helping retain usable staircase width. Indoor and outdoor configurations, finish options and several platform sizes are available.

Final platform size, rail arrangement and equipment options should be confirmed against the staircase and the user requirements before quotation or installation.

Product questions

Frequently asked questions

Is Delta designed for straight or curved stairs?

Delta is designed for straight staircases. A different platform stairlift model should be assessed where the route includes curves or landings.

Can Delta be installed outdoors?

Yes. An outdoor configuration is available. The final materials, finish and installation arrangement must be confirmed for the site conditions.

How much staircase width is needed?

The manufacturer lists installations from 890 mm stair width. Actual clearance depends on the platform, rail and staircase, so suitability must be confirmed by a site assessment.

Can Delta be used without a wheelchair?

An optional folding seat is available for some configurations. Confirm the intended use and selected equipment during the site assessment.
