The Kirk BH-1 Ballhead with Quick Release is a rugged and well-designed ballhead. It features the same efficiency of design and rugged construction that make other Kirk products so popular. Weighing in at under 2 lbs, this head is rated to support up to 50 lbs. In addition to the large single-action locking knob, the BH-1 also features two smaller knobs. One controls the 360° panning control, and the other the amount of ball friction.
The BH-1 ballhead comes with a universal quick release clamp that is compatible with all Arca-type plates. All external components are crafted from tough 6061-T aircraft aluminum including the solid, captive-design knobs, and the internal metal parts are stainless steel and brass to avoid corrosion. The ballcup is produced from self-lubricating Delrin composite.
