The standard 4000 stem handles those forces adequately; the Deluxe Stem Support handles them with no flex at all. The practical result is a vise that rotates with identical play-free smoothness whether the hook in the jaws is a size 20 RS2 or a chunky saltwater baitfish hook — the support prevents any micro-movement at the stem without adding friction to the rotary action.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"standard-markdown grid-cols-1 grid [\u0026amp;_\u0026gt;_*]:min-w-0 gap-3\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eEverything above the stem is standard Presentation 4000. The cam-operated jaws cover #28 through 4\/0 with a consistent grip and no flex across the full range — the same jaw that seats a fine-wire midge hook without over-clamping holds a 10\/0 tarpon hook without slipping under dense material pressure. Rotary tension is adjustable, the rotation is true on the horizontal axis, and the machining is commercial-grade — built for the kind of sustained production volume where a vise needs to perform identically on the thousandth fly as it did on the first. \u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"standard-markdown grid-cols-1 grid [\u0026amp;_\u0026gt;_*]:min-w-0 gap-3\"\u003e\n\u003ch3 class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cem\u003eFeatures\u003c\/em\u003e\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"standard-markdown grid-cols-1 grid [\u0026amp;_\u0026gt;_*]:min-w-0 gap-3\"\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eVise type:\u003c\/strong\u003e True rotary\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eJaw operation:\u003c\/strong\u003e Cam-operated; premium precision jaw engineering\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eRotary tension:\u003c\/strong\u003e Adjustable; play-free rotation throughout service life\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Commercial-grade precision-machined\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eStem support:\u003c\/strong\u003e Deluxe Stem Support — additional rigidity under heavy fly loads without added rotary friction\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eHook range:\u003c\/strong\u003e #28–4\/0\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eFly applications:\u003c\/strong\u003e Full range — midge through tarpon, with emphasis on large and heavy patterns\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eHand orientation:\u003c\/strong\u003e Left-hand or right-hand\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Renzetti","offers":[{"title":"Right-handed","offer_id":48532038385893,"sku":"OF-930442-RPED","price":574.95,"currency_code":"USD","in_stock":true},{"title":"Left-handed","offer_id":48532038353125,"sku":"OF-930442-LPED","price":574.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0639\/3377\/6101\/files\/P4012StemSupport.jpg?v=1773420449","url":"https:\/\/www.jsflyfishing.com\/products\/renzetti-presentation-4000-vise-with-deluxe-stem-support","provider":"J.
