A two-inch riser bracket that lifts a roof top tent up off the rack rails.

Risers exist to solve clearance problems. Two inches is usually enough to clear a low tonneau cover, a cross bar, or the lip of a bed rail so the tent sits flat and opens without fouling on anything. It is the smallest of the three heights available.

If you are not sure how much lift you need, measure the tallest thing between the rack rails and the underside of the closed tent, then add a little — a riser that is slightly too tall costs you nothing, one that is too short does not solve the problem.

Four and seven inch versions are also available.
