Installation with the Quick-Grip System

Installation and/or removal of the Ascent Rooftop Cargo Box from your rack is easy via Thule's patented Quick-Grip mounting system. This tool-free mounting system allows you to attach your rooftop box to virtually any roof rack in less than 5 minutes. The Quick-Grip system utilizes a two-armed pincer mechanism controlled by a simple knob control. The Ascent contains four of these knobs each embedded along internal tracks/strips within the bottom of the box. These can be moved forward or back along these tracks to accommodate your existing rack crossbar configuration and the length of your vehicle. As a knob is turned, the pincers of the Quick-Grip are released down and inward from the bottom the cargo box. These clamp around crossbars providing fast, maximized holding power that you can count on.

Simple Use, Stowage and Security

Once Thule's Ascent Rooftop Cargo Box is installed it is ultra easy to use. Secure, slip-free stowage of gear is provided via two tie down straps, included with the cargo box, that connect to the inner edges of the Quick-Grip units and cinch down tightly. In addition, easy access to gear is guaranteed with Thule's dual-side opening system built into the lid of Ascent series models that allows the lid to be opened from either lengthwise side of the box. This system allows for one-handed usage, with the lid staying in place when opened. Finally, the Ascent Rooftop Cargo Box provides for maximum and convenient security of your gear via an oversized lock with an ergonomic knob that is easy to grasp and turn, even while wearing gloves. A duplicate key is included with each unit, and new lock cores and lock upgrades can be added to existing units as the need arises.

About Thule

Thule was founded in 1942 by the Thulin family, when Eric Thulen, a true lover of the outdoors, put the Thule name on a pike trap he designed and began to sell in Scandinavia. It wasn't long before he added other practical items to the company's portfolio. By the 1960s, the company began to concentrate on car-related products, including its first roof rack. The Thulin family sold Thule to the publicly listed company Eldon in 1979, and it has continued to grow both organically and through acquisitions ever since. The Thule Group is a world leader in providing transport solutions for an active life.
