By mounting two Arca-type clamps back-to-back, it provides a rock-solid connection between any two Arca-compatible components, such as a lens foot and an adapter or two multipurpose rails.\n\u003c\/p\u003e \n\u003cp\u003e \n    \u003cstrong\u003eAdvanced Safety and Field Reliability:\u003c\/strong\u003e Engineered for the rigors of professional field work, the F51 incorporates deep safety relief grooves as a critical fail-safe. If your plates or rails are equipped with safety stops, these grooves prevent your camera or lens from sliding out if a clamp is partially open. The unyielding 6061-T6 aluminum construction ensures zero flex, providing the structural integrity and precision required for the most demanding technical photography. \n\u003c\/p\u003e\n\n\u003c!-- Technical Specifications --\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e \n\u003cul\u003e \n    \u003cli\u003e\n\u003cstrong\u003eJaw Length:\u003c\/strong\u003e 2.375 Inches (60.3mm)\u003c\/li\u003e \n    \u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e Back-to-Back Dual Side Clamp\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eKnob Type:\u003c\/strong\u003e Dual Black Captive Knobs (Field-Safe Design)\u003c\/li\u003e \n    \u003cli\u003e\n\u003cstrong\u003eSafety Feature:\u003c\/strong\u003e Deep Relief Grooves for Safety Stops\u003c\/li\u003e \n    \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e CNC Machined 6061-T6 Aluminum\u003c\/li\u003e \n    \u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Black Hard-Coat Anodized\u003c\/li\u003e \n    \u003cli\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e Made in the USA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Hejnar Photo","offers":[{"title":"Default Title","offer_id":67701597175913,"sku":"F51","price":75.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0794\/1278\/9353\/files\/F51-2.jpg?v=1792110954","url":"https:\/\/www.hejnarphotostore.com\/products\/f51-dual-side-back-to-back-arca-swiss-clamp","provider":"Hejnar Photo","version":"1.0","type":"link"}
