Dot Line 5.75" Vacuum Cup with Ballhead & Quick Release

The Dot Line 5.75" Vacuum Cup with Ballhead & Quick Release securely attaches to car windows, doors, hoods, and other smooth surfaces and supports camera/accessory loads up to 50 lb. It uses a push-pump mechanism to pump the air out between the cup and mounting surface, and a red line imprinted on the pump lets you know whether any air is left or has seeped back in. The cup is 5.75" in diameter and features a ballhead with a quick release adapter and 1/4"-20 post fixed on top. The quick release adapter removes from the post to let you efficiently attach other equipment. The 1/4"-20 post supports cameras, lights, mics, and other accessories, and the ballhead can be rotated, tilted, and swiveled.
