Arca-Swiss Quick Link separate base. With an extra Arca-Swiss Quick Link base, you can use the Quicklink set with two different tripods/light stands. You should already have the Quick Link Set. Description Installation is simple and once installed, ARCA-SWISS QuickLink components can remain in place. Thread the QuickLink mount receiver to the top of your tripod (purchased separately). Next, attach the QuickLink head connecting disc to the base of your tripod head, using the supplied Allen wrench. Once both components are mounted, drop the tripod head into the tripod receiver mount and rotate the knurled locking ring clockwise until snug. To unlink, turn the knurled ring counter clockwise and lift the head to remove it. Specification Manufacturer SKU 802320.2 Brand Arca Swiss Fit Arca Swiss Monoball / 3/8" Tripod Screw Dimensions No
