The Quick-Link Tripod Head Quick Release Set from Arca-Swiss combines a mounting receiver for tripods and an insert disc plate for tripod heads, which together make attaching and detaching a tripod head quick and simple. The Quick-Link disc mounts on the base of any tripod head, and the receiver to the mounting plate mounts on the leg set. Then simply place the head assembly into the receiver and twist the knurled, bayonet-type locking ring to secure it in place. Additional disc mounts are available, so switching heads takes just moments - making working with multiple heads quick and easy. There's no more need for packing multiple tripods when traveling or working on location. The installed plates can be left permanently in place, so the tripod can be set up and ready to go in just moments.
