Thule 250 Roof Top Combi-Box for Sale. Strong double-walled construction that can easily carry over 100 lbs of gear. Has two heavy duty locking latches (with key) plus a snap down latch on each end. A nice feature of this box is that the hinges can be reversed if needed. The dimensions are 91" long x 22" wide x 14" tall, and it weights around 32 lbs. Can be mounted on round, square and most factory crossbars with the appropriate mounting hardware (which is not included). Used, but in good clean condition.
