This Yakima ButtonDown 6 rack is new in the box - never used!
It will carry 4-6 pairs of skis (depending on widths) or 4 snowboards or a combination.
Comes with dual mounting clamps that initially fit Yakima round bars but can easily (and permanently) be altered to fit Thule square bars by snapping out the round-bar inserts.
Also included are adjustable/removable lift brackets (for added snowboard binding clearance), locks and key.
***FOR FACTORY CROSSBARS: I have a several sets of Mighty Mount adapter clamps for attaching this rack to various factory crossbars I'll add a set for just $15 extra ($35 extra retail).
