{"product_id":"used-open-box-ring-stretcher-reducer-6-spline","title":"Used Open-Box Value Line Ring Stretcher \u0026 Reducer","description":"\u003cp\u003eThe Value Line 6 Spline Ring Stretcher \u0026amp; Ring Reducer is a professional-grade bench tool designed to stretch and reduce plain gold and silver wedding bands. This upright ring stretcher features a 6-spline mandrel graduated in USA ring sizes 1–15 that expands on the downstroke of the handle, providing smooth, controlled enlargement of non-ferrous, non-stone-set plain wedding bands.\u003c\/p\u003e\n\u003cp\u003eThe 6-spline design delivers a gentler stretching action compared to 4-spline stretchers, distributing force more evenly and placing less stress on the ring during sizing. Stretching is a gradual process, and the additional splines help prevent the sudden deformation that can occur with fewer-spline units.\u003c\/p\u003e\n\u003cp\u003eWhat distinguishes this tool from similarly styled units is the inclusion of a smooth, polished double-sided band reducing plate. Most comparable ring stretcher\/reducer combinations feature crudely finished reducing plates; this unit's plate is finished to a standard on par with Italian versions, helping minimize marring during the reduction process. The double-sided plate shares the same range of holes on each face, but the two sides differ in the slope of their depressions – one side features a more steeply cut profile – allowing the operator to select the appropriate side for compressing and slightly size-shrinking narrow, domed-shaped bands.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eImportant Operator Notes: Carefully inspect all bands for previous signs of sizing before stretching. Bands that have been previously sized and soldered can split at the seam if stretching is attempted. Seamless precious metal wedding bands (gold and platinum) can be enlarged using the vertical ring stretcher; the amount of enlargement depends entirely on the thickness and type of band. Thin bands size up less than thicker bands. The reducing plate is used to slightly reduce the size of plain round precious metal (gold, silver, and platinum) wedding bands – size reduction is typically no more than 0.5 of a USA finger size and depends on the thickness and width of the band.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e6-spline mandrel graduated in USA ring sizes 1–15\u003c\/li\u003e\n\u003cli\u003eMandrel expands on the downstroke of the handle for controlled stretching\u003c\/li\u003e\n\u003cli\u003eGentler stretching action than 4-spline ring stretchers – less stress on the band\u003c\/li\u003e\n\u003cli\u003eSmooth, polished double-sided band reducing plate\u003c\/li\u003e\n\u003cli\u003eReducing plate features two sides with different depression slopes for versatility\u003c\/li\u003e\n\u003cli\u003eBase includes four mounting holes for securing to a bench or worktable\u003c\/li\u003e\n\u003cli\u003eFor use with non-ferrous metals only (gold, silver, platinum, palladium, etc.)\u003c\/li\u003e\n\u003cli\u003eNot for use on steel bands or stone-set rings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eRing Size Range\u003c\/th\u003e\n\u003ctd\u003eUSA sizes 1–15\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHeight\u003c\/th\u003e\n\u003ctd\u003e17 in (430 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFootprint\u003c\/th\u003e\n\u003ctd\u003e7 in × 5 in (175 mm × 127 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSpline Count\u003c\/th\u003e\n\u003ctd\u003e6\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCompatible Metals\u003c\/th\u003e\n\u003ctd\u003eNon-ferrous metals – gold, silver, platinum, palladium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMounting\u003c\/th\u003e\n\u003ctd\u003eFour base mounting holes (hardware not included)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInstructions Included\u003c\/th\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eManufactured In\u003c\/th\u003e\n\u003ctd\u003eIndia\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e6-spline ring stretcher with graduated mandrel\u003c\/li\u003e\n\u003cli\u003eDouble-sided band reducing plate\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eNotes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eThis is a \u003cstrong\u003eused open-box closeout\u003c\/strong\u003e item that was returned due to cosmetic damage during shipping. \u003cem\u003e\u003cstrong\u003ePlease look carefully at the images provided.\u003c\/strong\u003e\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003eMounting hardware is not included.\u003c\/li\u003e\n\u003cli\u003eNo instructions are included with this tool.\u003c\/li\u003e\n\u003cli\u003eNot suitable for stretching or reducing steel bands.\u003c\/li\u003e\n\u003cli\u003eNot suitable for stone-set rings.\u003c\/li\u003e\n\u003cli\u003eInspect all bands for prior sizing or solder seams before stretching – previously soldered bands risk splitting at the seam.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Value Line","offers":[{"title":"Default Title","offer_id":48144704274646,"sku":"999.148339","price":160.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/999.148339_thumb_e5cc0ddb-4d46-43b2-a1e5-b5268aa7e696.jpg?v=1776809421","url":"https:\/\/www.ottofrei.com\/products\/used-open-box-ring-stretcher-reducer-6-spline","provider":"Otto Frei","version":"1.0","type":"link"}
