The Sirui PH-180 is a replacement plate specifically designed for compatibility with the SI-PH20 model. This interchangeable plate serves as a camera mounting interface for tripod systems and is made from durable aluminum alloy for reliable performance and long-term use. The plate has standard dimensions of approximately 38 mm in width and 45 mm in length, with a thickness of 8 mm, weighing around 25 grams to minimize additional bulk in your camera setup. It features a standard 1/4 inch (6.35 mm) thread that is compatible with most digital cameras and camcorders, along with a secure locking mechanism for stable camera attachment during operation. The anodized black surface provides corrosion resistance and maintains a uniform appearance over time. This plate is designed to maintain precise camera positioning while offering quick-release functionality for efficient workflows. The design focuses on maintaining camera stability during stationary shots and position adjustments, with reinforced construction at load points to safely handle equipment weights of up to 3 kilograms. The surface includes non-slip rubber padding to protect the camera base from scratches and provides additional grip. All machining tolerances are within 0.1 mm for consistent fit and reliable operation over multiple attachment cycles. The plate has been tested for repeated mounting and dismounting cycles to ensure lasting performance in professional photography environments. Compatibility is confirmed with Sirui SI-PH20 quick-release systems and similar mounting mechanisms according to standard Arca-Swiss specifications. The product is ready to use immediately and requires no additional tools or assembly steps.
