ProMediaGear CD40 Compatible Back-to-Back QR Clamps

While the ProMediaGear CD40 Arca-Swiss Compatible Back-to-Back QR Clamps set the standard for precision and versatility in the photography and videography accessory market, this product goes beyond the norm to offer unparalleled reliability and durability. Each set includes two robust 40mm wide clamps that are meticulously engineered to hold equipment securely in place. The clamps feature a 1/4-20 insert and a 3/8-16 insert, along with the necessary mounting screws for each insert, a mounting screw for the clamps, wrenches, and 2 precision-machined pins for flawless alignment.

Crafted with a hard-coated black anodized surface, these clamps are designed to withstand the rigors of frequent use in various environments, from studio to rugged outdoor settings. The nickel-chrome plated insert is a testament to the product's high-quality construction, ensuring that the threads maintain their integrity over time. This is a significant advantage over other designs where threads are cut directly into the aluminum body, which can lead to wear and eventual failure.

The CD40 clamps are not only sturdy and reliable but also incredibly versatile. They can be used for parallax offset, slide the rail applications, or separately, depending on your specific needs. The precision machining of these instruments means that even when the screw is removed, the clamps will remain firmly together, held in place by the pins with a tight, secure fit. To separate them, one must pull evenly due to the minimal play between the components. Additionally, when reassembling, the use of the large screw is essential to ensure both clamps are securely fastened together.

Whether you're mounting lights, flags, reflectors, or other equipment, the CD40 Compatible Back-to-Back QR Clamps offer a reliable solution that professionals and enthusiasts alike can trust for their creative setups. With their high-quality construction and thoughtful design, these clamps are an essential tool for anyone looking to enhance their photography or videography rig with equipment that promises both stability and adaptability.
