By allowing two rails to attach at a perfect 90-degree angle, it serves as a critical component for creating vertical masts in panoramic photography or building custom lens support brackets for heavy telephoto glass.\n\u003c\/p\u003e \n\u003cp\u003e \n    \u003cstrong\u003eAdvanced Safety and Field Reliability:\u003c\/strong\u003e Beyond its rail-to-rail capabilities, the F52 offers the flexibility to be mounted directly onto compatible supports, making it a versatile \"problem-solver\" for technical gear kits. The integrated safety relief grooves serve as a vital fail-safe; when used with plates featuring safety stops, they prevent your camera or lens from sliding out if a clamp is accidentally left partially open. This clamp delivers 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\u003eOrientation:\u003c\/strong\u003e Perpendicular (90-Degree) Double 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\u003eCenter Mounting:\u003c\/strong\u003e Integrated Center Socket\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":67701597208681,"sku":"F52","price":80.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0794\/1278\/9353\/files\/F52-2.jpg?v=1792110956","url":"https:\/\/www.hejnarphotostore.com\/products\/f52-perpendicular-double-arca-swiss-clamp","provider":"Hejnar Photo","version":"1.0","type":"link"}
