The Convi Clamp With Adjustable Handle from Kupo has a hexagonal receiver that accepts many Convi accessories to mount almost any light fixture, camera or accessory. This clamp has a ratcheted handle that allows you to reposition it in case you don’t have clearance to rotate the handle in a complete circle to tighten or loosen it. The clamp features a lightweight alloy construction with stainless steel bolts, and has a stealthy black finish.
