The Extension Trolley Seat Basket Jumbo from SENSAS is a very well-invented tool! If you have to take a lot of material with you, this Jumbo extension for your seat is an indispensable tool. To attach this extension piece to the back of your seat basket, simply remove the protective covers and place the extension piece in the frame of your seat basket and then attach the matching wheels. Thanks to a smart screw system, the extension can be adapted to all our Match, Jumbo and Nanoflex seat baskets. On the extension you can take a lot of extra material with you (think of: harness boxes, roll supports, accessory bags, etc.) and you get a better weight distribution while maintaining a low center of gravity. You don't have to leave anything at home in the future - thanks to the Jumbo extension you can take everything with you!
