The blue AirHed Pro Ball Head from 3 Legged Thing is an Arca-type ball head boasting a 88.0 lb load capacity and the ability to be attached to tripods or other support systems with a 3 8 -16 mount. The included QR-OCTA Quick Release Plate is compatible with 1 4 -20 mounts, and is secured onto the integrated clamp on the top of the head s ball-and-socket joint via a knurled, locking knob.
