Check the listing for details. Gibraltar SC-GRSQT (3-pack) Bundle. Condition: New. Listed at 80.01 USD. Build your rack in confidence with Gibraltar. The Road Series Quick T-Leg Clamp attaches one rack bar to another at a fixed 90-degree angle. A traditional right-angle clamp will offset the crossbar of your rack from the leg. But the Gibraltar SC-GRSQT positions the crossbar and leg in-line with one another. And the quick-release mechanism makes this clamp fast to install and remove.
