TracRac™ G2 Sliding Base Rails (21781) by Thule®. 1 Pair. Lock your racks to the sliding rail to prevent theft or unauthorized reconfiguration with these locking knobs. When locked, the knob simply spins freely without loosening. Includes 2 knobs and 2 keys. Manufactured from industry-leading materials using up-to-date equipment, it ensures everlasting reliability and enduring value. This product is distinguished by total quality assurance, unsurpassed by anybody else.
As easily as your TracRac sliding rack moves to accommodate your changing needs, it can just as easily be loosened up and slid out of the bed rails by persons unknown. If you often park your truck any place where you’re not comfortable leaving valuables in the bed or on the dash, you should get a pair of locking knobs for the rear rack.
