By centering the Arca-Swiss clamp directly over the head's panning axis, this plate restores the precision required for professional panoramic and macro photography.\n\u003c\/p\u003e\n\u003chr\u003e\n\n\u003c!-- ===================== QUICK OVERVIEW ===================== --\u003e\n\u003ch2\u003eQuick Overview\u003c\/h2\u003e\n\u003cul\u003e\n\t\u003cli\u003eModel: M410Long (Extended Version)\u003c\/li\u003e\n\t\u003cli\u003eCustom designed to align camera\/lens mount axis with the head's panning base\u003c\/li\u003e\n\t\u003cli\u003eEliminates rotational offset—essential for critical panoramic and macro work\u003c\/li\u003e\n\t\u003cli\u003eAllows Arca-type clamps to be positioned in 90-degree increments\u003c\/li\u003e\n\t\u003cli\u003eNote: Clamp cannot be oriented with the knob on the bubble level side\u003c\/li\u003e\n\t\u003cli\u003eSupports dual mounting: 2 or 3 screw configurations depending on clamp orientation\u003c\/li\u003e\n\t\u003cli\u003ePrecision CNC-machined from 6061-T6 aluminum with black anodizing\u003c\/li\u003e\n\t\u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003c!-- ===================== PRODUCT DESCRIPTION ===================== --\u003e\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003e\nStandard Manfrotto 410 arrangements often place the camera mount off-center from the panning axis, which is a major drawback for precision photography. The Hejnar Photo M410Long extended conversion plate solves this by ensuring that when you pan the head, both the head and your camera rotate around the exact same axis.\n\u003c\/p\u003e\n\u003cp\u003e\nThis extended plate is a \"killer\" upgrade that makes the 410 head useful again for critical macro and panoramic work. While this listing is for the \u003cstrong\u003eadapter plate only\u003c\/strong\u003e (clamp required separately), it provides a rock-solid foundation that accepts any modular Arca-style clamp. The plate is engineered for versatility, allowing 90-degree rotational steps to suit your preferred knob orientation.\n\u003c\/p\u003e\n\n\u003c!-- ===================== INSTALLATION ===================== --\u003e\n\u003ch2\u003eSimple 2-Step Installation\u003c\/h2\u003e\n\u003col\u003e\n\t\u003cli\u003eRemove the factory lock-down lever using the provided 3mm hex wrench.\u003c\/li\u003e\n\t\u003cli\u003eConnect the M410Long plate to the geared head using the provided 1\/4-20 and 10-32 screws.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003e\u003cem\u003eInstallation Tip: For a permanent, secure fit, the use of a removable thread locker (like blue Loctite) on mounting screws is recommended.\u003c\/em\u003e\u003c\/p\u003e","brand":"Hejnar Photo","offers":[{"title":"Default Title","offer_id":67701611397225,"sku":"M410Long","price":75.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0794\/1278\/9353\/files\/M410LongF63-2.jpg?v=1793841901","url":"https:\/\/www.hejnarphotostore.com\/products\/manfrotto-410-extended-arca-adapter","provider":"Hejnar Photo","version":"1.0","type":"link"}
