{"product_id":"borg-7844-m42p1-m39ad","title":"BORG 7844 M42P1-M39AD","description":"\u003ch2\u003eBORG 7844 M42P1-M39AD | Join M42P1 and M39 threaded parts\u003c\/h2\u003e\n\u003cp\u003eTo connect an M42P1-threaded part with an M39-threaded part, the BORG 7844 M42P1-M39AD provides a direct adapter between those two designations. It’s for photographers and optical-system users who are building around threaded components and need these particular interfaces to meet. The practical benefit is a simpler connection between parts that would otherwise have different thread sizes, helping you put together the setup you want without changing those components. The important detail is right in the name: M42P1 on one side of the pairing and M39 on the other. Use it when both parts match those designations and you want to bring them together in a single threaded connection. This is a specific-fit accessory, rather than a general-purpose solution for every threaded lens or accessory; its value depends on having the matching parts in your setup.\u003c\/p\u003e\n\n\u003cdiv class=\"specialist-note\"\u003e\n\u003ch3\u003eSpecialist Note\u003c\/h3\u003e\n\u003cp\u003eThe M42P1 and M39 thread designations are the key physical detail here: they tell you which two parts this adapter is intended to bring together. I’d recommend it to someone who already has components in both sizes and wants a straightforward way to connect them, rather than replace a part simply because its thread differs. For a tidy setup, match each component to its thread designation before you begin, then start the connection carefully so the threads meet cleanly. It’s a focused little accessory, so it won’t solve a mismatch involving other thread sizes. If your parts are M42P1 and M39, though, this is the specific pairing to consider.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eProduct: BORG 7844 M42P1-M39AD\u003c\/li\u003e\n\u003cli\u003eModel number: 7844\u003c\/li\u003e\n\u003cli\u003eThread designation: M42P1-M39\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BORG","offers":[{"title":"Default Title","offer_id":57563628994900,"sku":"BG-7844","price":47.56,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0780\/2493\/3716\/files\/BG-7844_01.jpg?v=1791804879","url":"https:\/\/www.htf-store.com\/it\/products\/borg-7844-m42p1-m39ad","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
