Flush Mount Bracket (4 in Set)The Flush Mount Bracket is designed for flush mounting The Bush Company's rooftop tents onto existing extruded rail on a roof rack or on the roof of a canopy and as the name suggests, this fitment solution provides a very low profile installation. For secure attachment of the roof top tent, we recommend a minimum of 8 brackets (2 sets of 4) be used. These can be attached as either two on either side of two of the extrusions on both sides of the tent
