All of the control knobs are cross-hatch knurled for easy gripping | ARCA-TYPE COMPATIBLE QUICK RELEASE SYSTEM - The Arca-type compatible quick release plate allows the camera and lens set to be quickly mounted. It incorporates a bubble level for precise horizontal alignment, and a +/- 25mm scale for precise quick release plate positioning. The included AQR-60 quick release plate has a D-ring 1/4"-20" mounting screw, rubber traction strips to prevent camera rotation, and security pins to prevent it from accidentally releasing from the mounting platform | SOLID BRASS-REINFORCED SOCKET: The base of the RTH-1050 ball head features an industry-standard 3/8"-16 mounting socket machined from corrosion-resistant brass, making it compatible with virtually any tripod leg set. The socket is made from reinforced brass to resist wear for long life and reliable, secure tightening | 90° NOTCH: Quickly change the camera orientation from landscape to portrait using the 90° notch.
