There is no question T-Track systems are becoming a staple within vehicle roof racks, crossbars, platform racks, etc. We wanted to make sure you can get your River Quiver as low profile as possible to any T-Track roof rack on the market which is why we came up with the LP T-Track Mount. This mount bridges the gap between our T-Track system (top and bottom on the River Quiver) with any T-Track roof rack to ensure your River Quiver is as flush as possible on your rig.
