The second‑generation duct mandrel is designed not only to verify that a duct is passable, but also to indicate if – and to what extent – the duct has been deformed.\u003c\/div\u003e\n\u003cdiv class=\"paragraph-in-scc-markdown-text ___1ngh792 ftgm304 f1iaxwol\" style=\"\"\u003eBy pulling the mandrel through the duct, the installer can directly read the maximum available free internal diameter (Ø) after any deformation. This provides a clear and reliable decision basis prior to subsequent cable or fiber installation, allowing preventive measures to be taken before unexpected and costly installation stops occur.\u003c\/div\u003e\n\u003cdiv class=\"paragraph-in-scc-markdown-text ___1ngh792 ftgm304 f1iaxwol\" style=\"\"\u003eThe mandrel features a mechanically expanding design with a clear scale that displays the reduced diameter when the duct has been exposed to external pressure. It is suitable for both new installations and inspection of existing duct systems. Multiple sizes are available, together covering duct diameters from Ø30 to Ø130 mm.\u003c\/div\u003e\n\u003cdiv style=\"line-height: 20px;\"\u003e\u003cbr\u003e\u003c\/div\u003e\u003cb\u003eKey Benefits\u003c\/b\u003e\n\u003cul style=\"\"\u003e\n\u003cli class=\"___ccc16d0 fje8fi8 f1ng9h0j f1bwykku f18jd3zf\" style=\"\"\u003eInspects ducts and verifies structural integrity\u003c\/li\u003e\n\u003cli class=\"___ccc16d0 fje8fi8 f1ng9h0j f1bwykku f18jd3zf\" style=\"\"\u003eDisplays the new maximum available free Ø diameter in case of deformation\u003c\/li\u003e\n\u003cli class=\"___ccc16d0 fje8fi8 f1ng9h0j f1bwykku f18jd3zf\" style=\"\"\u003eProvides a clear decision basis prior to cable and fiber pulling\u003c\/li\u003e\n\u003cli class=\"___ccc16d0 fje8fi8 f1ng9h0j f1bwykku f18jd3zf\" style=\"\"\u003ePrevents sudden installation stops and reduces time and cost overruns\u003c\/li\u003e\n\u003cli class=\"___ccc16d0 fje8fi8 f1ng9h0j f1bwykku f18jd3zf\" style=\"\"\u003eAvailable in multiple sizes covering ducts Ø30–Ø130 m\u003c\/li\u003e\u003c\/ul\u003e\u003c\/div\u003e","brand":"Sahlins Sweden","offers":[{"title":"30-46","offer_id":57821091234166,"sku":"7404-0030","price":0.0,"currency_code":"SEK","in_stock":true},{"title":"47-70","offer_id":57821091266934,"sku":"7404-0047","price":0.0,"currency_code":"SEK","in_stock":true},{"title":"70-100","offer_id":57821091299702,"sku":"7404-0070","price":0.0,"currency_code":"SEK","in_stock":true},{"title":"85-115","offer_id":57821091332470,"sku":"7404-0085","price":0.0,"currency_code":"SEK","in_stock":true},{"title":"105-135","offer_id":57821091365238,"sku":"7404-0105","price":0.0,"currency_code":"SEK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0957\/0726\/7446\/files\/7404-Tolk.webp?v=1778234484","url":"https:\/\/sahlins.com\/en\/products\/dynamic-duct-mandrel","provider":"Sahlins Sweden","version":"1.0","type":"link"}
