The Sirui PH-85 is an Arca-compatible quick release plate designed as a replacement part for the PH-10 carbon fiber gimbal head. This precision-crafted plate measures 85 mm in length, 38 mm in width, and 15 mm in thickness, weighing 68 grams. Made from high-quality aluminum alloy, it features the standardized Arca-Swiss dovetail design with a secure locking mechanism for reliable camera attachment. The plate includes a standardized 1/4-inch tripod thread, compatible with most DSLR and mirrorless cameras. Specifically developed for the Sirui PH-10 gimbal system, this quick release plate can also be used with other Arca-compatible gimbal heads that accept standard 85 mm plates, although users should verify dimensional compatibility before use. The manufacturing process ensures precise tolerances and a smooth surface finish for secure camera attachment and stable operation. The plate maintains a consistent thickness throughout its length to prevent bending under heavy camera weights. The anodized surface treatment provides corrosion resistance and durable wear properties. Installation requires no special tools and follows standardized quick release plate attachment procedures. This component serves as a functional replacement part for photographers who need additional mounting plates or wish to replace existing plates in their gimbal setup.
