The Mounting Extension Set with rear wheel support is designed to allow the installation of PARKIS bike lifts at a distance from a wall. That is necessary in extra space-saving mode, where several bike lifts can be installed incredibly close to each other (40 cm/ 16″ or less) or when the bike rack needs to be installed on a distant pillar. This accessory pulls PARKIS from 19 cm (7.48″) of the wall surface. The set includes a Rear Wheel Support plate, which is recommended for user comfort, all necessary screws and an installation guide. Made of stainless steel.
