It provides a stronger, more stable mounting platform than the factory foot while adding the versatility of an integrated stainless‑steel Quick Detach (QD) socket. The QD interface accepts standard push‑button QD mounts, offering a secure and reliable connection for QD‑compatible straps and support systems.\n\u003c\/p\u003e\n\n\u003cp\u003e\nThe QD system has been trusted for decades by NASA, law enforcement, and military agencies due to its resistance to accidental release and its ability to maintain a locked connection under dynamic movement. The integrated QD socket allows the lens to be carried safely and confidently while maintaining full compatibility with Arca‑type clamps, rails, and tripod heads.\n\u003c\/p\u003e\n\n\u003cp\u003e\nThe foot features a precision‑cut double‑dovetail profile, allowing clamping from either the top or bottom surface. This design is ideal for rail‑based setups, macro stages, gimbal heads, and multi‑axis support systems. The dual‑surface dovetail also accommodates flash brackets and accessories that require a secondary clamping surface.\n\u003c\/p\u003e\n\n\u003cp\u003e\nIf your mounting screws loosen over time, a small amount of removable thread locker such as Loctite 242 may be used for added security. This ensures long‑term stability without compromising serviceability.\n\u003c\/p\u003e\n\n\u003cp\u003e\nEach foot is CNC‑machined from 6061‑T6 aluminum for strength, precision, and dimensional stability. The black anodized finish provides excellent wear resistance, while stainless‑steel hardware ensures corrosion resistance and long‑term reliability. Like all Hejnar Photo components, this foot is manufactured in the USA with tight tolerances and professional‑grade machining standards.\u003c\/p\u003e","brand":"Hejnar Photo","offers":[{"title":"Default Title","offer_id":67701592129641,"sku":"CFR-007-C1","price":65.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0794\/1278\/9353\/files\/CFR-007-2.jpg?v=1792110721","url":"https:\/\/www.hejnarphotostore.com\/products\/replacement-foot-canon-rf-800mm-f11-qd-socket","provider":"Hejnar Photo","version":"1.0","type":"link"}
