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

Four inches is the middle height, and the one that usually clears a hard tonneau cover or a taller bed rail while still keeping the tent low enough not to change how the vehicle handles noticeably.

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.

Two and seven inch versions are also available.
