{"title":"1\/2\" Inside Diameter (ID) Rubber Grommets","description":"\u003cp\u003eEvery grommet on this page has a 1\/2\" inside diameter (ID), the clear opening left for whatever passes through it. A 1\/2\" opening is the usual choice for a single heavy power cord, a 3\/8\" tube or a few thin signal wires. The 5 styles here fit panel holes of 5\/8\" or 3\/4\", with groove widths of 1\/16\", 3\/32\", 1\/8\" and 3\/8\", so you can match both the hole you drilled and the thickness of the material.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow to size a 1\/2\" ID grommet.\u003c\/strong\u003e Start with the item going through: measure its outside diameter, or the widest point of any plug or fitting that has to pass, and make sure it clears 1\/2\". Next, measure the hole with calipers; the grommet should be listed as fitting that exact hole size, because the groove has to sit tight against the edge. Last, measure the panel thickness and choose a groove width equal to it or slightly wider. If the panel is thicker than the widest groove listed, drill to a larger hole size instead and step up in ID. Searching by hole size rather than opening? Use the \"fits holes\" link below.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eRelated sizes:\u003c\/strong\u003e \u003ca href=\"\/collections\/3-8-inside-diameter-rubber-grommets\"\u003e3\/8\" ID grommets\u003c\/a\u003e · \u003ca href=\"\/collections\/3-4-inside-diameter-rubber-grommets\"\u003e3\/4\" ID grommets\u003c\/a\u003e · \u003ca href=\"\/collections\/1-2-groove-diameter-rubber-grommets-fits-1-2-panel-holes\"\u003eGrommets that fit 1\/2\" holes\u003c\/a\u003e · \u003ca href=\"\/collections\/rubber-grommets\"\u003eAll rubber grommets\u003c\/a\u003e\u003c\/p\u003e","products":[{"product_id":"1-2-inside-diameter-rubber-grommet-fits-3-4-panel-holes-groove-diameter","title":"1\/2\" Inside Diameter Rubber Grommet - 1\/8\" Groove Width - Fits: 3\/4\" Holes","description":"\u003ch2\u003eProduct Overview:\u003c\/h2\u003e\n\u003cp\u003e1\/2\" Inside Diameter Rubber Grommet - 1\/8\" Groove Width - Fits: 3\/4\" Holes. Ideal for passing wires through panels without risking damage or abrasion by acting as a protective barrier, extending the lifespan of your cables and wires.\u003c\/p\u003e\n\u003ch3\u003eProduct Specifications:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eInside Diameter: 1\/2\"\u003c\/li\u003e\n\u003cli\u003eGroove Width: 1\/8\"\u003c\/li\u003e\n\u003cli\u003eGroove Diameter: 3\/4\"\u003c\/li\u003e\n\u003cli\u003eOutside Diameter: 1\"\u003c\/li\u003e\n\u003cli\u003eThickness: 1\/2\"\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Rubberfeetwarehouse","offers":[{"title":"Default Title","offer_id":41741758222,"sku":"RG30123425","price":0.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0661\/8741\/products\/Rubber_Grommet_RG1234.jpg?v=1738362049"},{"product_id":"1-2-inside-diameter-rubber-grommet-3-32-groove-width-fits-3-4-holes","title":"1\/2\" Inside Diameter Rubber Grommet - 3\/32\" Groove Width\" - Fits 3\/4\" Holes","description":"\u003ch2\u003eProduct Overview:\u003c\/h2\u003e\n\u003cp\u003e1\/2\" Inside Diameter Rubber Grommet - 3\/32\" Groove Width\" - Fits 3\/4\" Holes Ideal for passing wires through panels without risking damage or abrasion by acting as a protective barrier, extending the lifespan of your cables and wires.\u003c\/p\u003e\n\u003ch3\u003eDimensions:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan style=\"font-size: 1rem;\"\u003eInside Diameter: 1\/2\" \u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003eGroove Width: 3\/32\"\u003c\/li\u003e\n\u003cli\u003eGroove Diameter: 3\/4\"\u003c\/li\u003e\n\u003cli\u003eOutside Diameter: 7\/8\"\u003c\/li\u003e\n\u003cli\u003eThickness: 11\/32\"\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Rubberfeetwarehouse","offers":[{"title":"Default Title","offer_id":2704527818776,"sku":"RG30123413","price":0.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0661\/8741\/products\/12_1132_grom.jpg?v=1738362010"},{"product_id":"1-2-inside-diameter-rubber-grommet-3-8-gw-fits-3-4-panel-hole","title":"1\/2\" Inside Diameter Rubber Grommet - 3\/8\" GW - Fits 3\/4\" Panel Hole","description":"\u003ch2\u003eProduct Overview:\u003c\/h2\u003e\n\u003cp\u003e1\/2\" Inside Diameter Rubber Grommet - 3\/8\" GW - Fits 3\/4\" Panel Holes.
