Sirui HA-77 Horizontal Arm
Product Description: The HA-77 Horizontal Arm from Sirui is a telescoping cross arm that can be combined with a tripod or stand to create a miniature camera boom. Its total 30.3" of length is provided by a two-section tube that rests on top of a tripod head, which features 360° of independent rotation. The tube and the head are connected by a fulcrum, which enables 90° of upwards or downwards tilt that can be locked into place. This allows an attached camera to be easily raised toward an elevated subject or over a scene. For subjects along the ground, the HA-77 Horizontal Arm can be used to obtain low angles while its user stands comfortably behind the camera. This horizontal arm has a load capacity of 11 lb and is compatible with tripods or support systems that feature a 3/8"-16 mount. Thumbscrew locks are positioned on the HA-77 Horizontal Arm's tripod head, fulcrum, and the clamp that holds its telescoping, two-section tube on the fulcrum. By loosening each of these thumbscrew locks, the tripod head can be swiveled, the fulcrum tilted, and the two-section tube pushed toward or pulled away from the subject. Additionally, a twist lock on the two-section tube allows for rapid deployment of its second section.
