{"title":"1\" Inside Diameter (ID) Rubber Grommets","description":"\u003cp\u003eEvery grommet on this page has a 1\" inside diameter (ID), the clear opening left for whatever passes through it. A 1\" opening suits a small hose, a pair of power cords, or 3\/4\" EMT conduit passing through sheet metal, plywood or a plastic housing. The 7 styles here fit panel holes of 1-1\/4\" or 1-3\/8\", with groove widths of 1\/16\", 3\/16\", 1\/4\", 3\/8\" and 1\/2\", 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\" 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\". 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\/3-4-inside-diameter-rubber-grommets\"\u003e3\/4\" ID grommets\u003c\/a\u003e · \u003ca href=\"\/collections\/1-1-4-inside-diameter-rubber-grommets\"\u003e1-1\/4\" ID grommets\u003c\/a\u003e · \u003ca href=\"\/collections\/1-groove-diameter-rubber-grommets-fits-1-panel-holes\"\u003eGrommets that fit 1\" holes\u003c\/a\u003e · \u003ca href=\"\/collections\/rubber-grommets\"\u003eAll rubber grommets\u003c\/a\u003e\u003c\/p\u003e","products":[{"product_id":"1-inside-diameter-rubber-grommet-fits-1-1-4-panel-holes-1-4-gw","title":"1\" Inside Diameter Rubber Grommet - 1\/4\" Groove Width - Fits 1-1\/4\" Holes","description":"\u003ch2\u003eProduct Overview:\u003c\/h2\u003e\n\u003cp\u003e1\" Inside Diameter Rubber Grommet - 1\/4\" Groove Width - Fits 1-1\/4\" Holes.
