This custom accessory seamlessly transforms your factory lens foot into a native Arca-Swiss component, providing a rock-solid connection to your tripod head that completely eliminates the unwanted vibrations, flex, and play associated with generic universal mounting adapters. \n\u003c\/p\u003e \n\u003cp\u003e \n    Security and equipment protection remain paramount in this design. Because tracking fast-moving wildlife or sports subjects puts significant torsional stress on your support gear, single-screw plates can easily slip or spin out of alignment under load. This rail completely resolves that physical constraint by deploying a robust \u003cstrong\u003etwo-screw mounting system\u003c\/strong\u003e. By locking the plate down utilizing both the 1\/4-20 thread and the larger 3\/8-16 thread standard on the G Master lens foot simultaneously, it forms an unyielding physical connection that completely eliminates twisting and ensures vibration-free tracking. By intentionally eliminating a locating pin, this plate maximizes flat metal-on-metal contact against the original equipment foot without causing fitment interference.\n\u003c\/p\u003e \n\u003cp\u003e \n    The core operational feature of this plate variant is the integration of a high-performance \u003cstrong\u003estainless steel QD socket\u003c\/strong\u003e. This secure quick-disconnect mechanism—widely trusted for decades by industries around the world including NASA, law enforcement, and military agencies—inhibits accidental removal, allowing you to confidently carry your telephoto setup suspended from a heavy-duty shoulder sling, such as a \u003cstrong\u003eBlackRapid\u003c\/strong\u003e strap fitted with a push-button QD swivel. When it is time to capture a shot, the push-button mechanism releases instantly, and the low-profile plate slides directly into any standard Arca-type quick-release clamp. \n\u003c\/p\u003e","brand":"Hejnar Photo","offers":[{"title":"Default Title","offer_id":67701623292009,"sku":"SLP-003-2S-L","price":50.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0794\/1278\/9353\/files\/SLP-003-2S-L-2.jpg?v=1792111675","url":"https:\/\/www.hejnarphotostore.com\/products\/sony-100-400-gm-dual-screw-qd-plate","provider":"Hejnar Photo","version":"1.0","type":"link"}
