{"title":"3\/4\" Inside Diameter (ID) Rubber Grommets","description":"\u003cp\u003eEvery grommet on this page has a 3\/4\" inside diameter (ID), the clear opening left for whatever passes through it. A 3\/4\" opening fits a 1\/2\" OD tube, a thick extension cord, or a small group of low-voltage cables. The 13 styles here fit panel holes of 7\/8\", 1\", 1-1\/16\", 1-1\/8\" or 1-1\/4\", with groove widths of 1\/16\", 1\/8\", 3\/16\", 1\/4\" 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 3\/4\" 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 3\/4\". 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\/1-2-inside-diameter-rubber-grommets\"\u003e1\/2\" ID grommets\u003c\/a\u003e · \u003ca href=\"\/collections\/1-inside-diameter-rubber-grommets\"\u003e1\" ID grommets\u003c\/a\u003e · \u003ca href=\"\/collections\/3-4-groove-diameter-rubber-grommets-fits-3-4-panel-holes\"\u003eGrommets that fit 3\/4\" holes\u003c\/a\u003e · \u003ca href=\"\/collections\/rubber-grommets\"\u003eAll rubber grommets\u003c\/a\u003e\u003c\/p\u003e","products":[{"product_id":"rubber-grommets-3-4-inside-diameter-fits-1-1-16-panel-holes-3-8-thick","title":"3\/4\" Inside Diameter Rubber Grommet - 1\/16\" Groove Width - Fits 1-1\/16\" Holes","description":"\u003ch2\u003eProduct Overview:\u003c\/h2\u003e\n\u003cp\u003e3\/4\" Inside Diameter Rubber Grommet - 1\/16\" Groove Width - Fits 1-1\/16\" 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.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eProduct Specifications:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eInside Diameter: 3\/4\"\u003c\/li\u003e\n\u003cli\u003eGroove Width: 1\/16\"\u003c\/li\u003e\n\u003cli\u003eGroove Diameter: 1-1\/16\"\u003c\/li\u003e\n\u003cli\u003eOutside Diameter: 1-3\/8\"\u003c\/li\u003e\n\u003cli\u003eThickness: 3\/8\"\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Rubberfeetwarehouse","offers":[{"title":"Default Title","offer_id":41783100964973,"sku":"RG3034111631","price":0.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0661\/8741\/products\/Rubber_Grommet_RG34111638_11.jpg?v=1738362046"},{"product_id":"rubber-grommet-3-4-inside-diameter-fits-1-panel-holes-9-16-thick","title":"3\/4\" ID Rubber Grommet for 1\" Hole – 3\/16\" Groove Width, 1-1\/4\" OD – Wire \u0026 Cable Grommet","description":"\u003ch2\u003eProduct Overview:\u003c\/h2\u003e\n\u003cp\u003e3\/4\" Inside Diameter Rubber Grommet - 3\/16\" Groove Width - Fits 1\" Holes\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eRubber Grommets are used for multiple projects.
