{"product_id":"concealed-joist-hanger","title":"Concealed Joist Hanger","description":"\u003cp\u003eA concealed joist hanger carries the end of a joist or beam where it meets a header, a ledger, or a wall at a right angle, with its mounting flanges hidden. The flanges sit within the joist's width, behind its end, so all you see is the steel along the joist's sides. Set your joist's size below, and it's made to fit. Also called an internal flange joist hanger.\u003c\/p\u003e\n\u003ch2\u003eHow it goes in\u003c\/h2\u003e\n\u003cp\u003eThe hanger bolts to the header first, through the flanges inside its pocket. The joist then goes in over them. Because the bolt heads or nuts stand inside the pocket, the end of the joist is grooved or notched to clear them. Plan that cut before you order.\u003c\/p\u003e\n\u003ch2\u003eConcealed or face-mount\u003c\/h2\u003e\n\u003cp\u003eChoose concealed for the cleaner look: no steel shows on the header at all. The price is the groove in the joist's end and more work to install. If you'd rather skip both, the \u003ca href=\"\/products\/face-mount-joist-hanger\"\u003eface-mount joist hanger\u003c\/a\u003e puts its flanges on the header's face, where the fasteners are easy to reach.\u003c\/p\u003e\n\u003ch2\u003eWhat you set, and what follows from it\u003c\/h2\u003e\n\u003cp\u003eYou set four sizes. The joist's width, which the configurator calls the width of beam, runs from 1 1\/2\" to 10\". The hanger's height runs from 3 1\/2\" to 12\". Together they cover 2x4 to 10x12. The beam flanges along the joist's sides run from 2 1\/2\" to 5\" wide. Fasteners run from 1\/4\" to 5\/8\". You also choose a straight or an angled saddle, the seat under the joist. That choice is only for looks.\u003c\/p\u003e\n\u003cp\u003eThe mounting flanges aren't yours to set, because they have to fit inside the pocket:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eA joist up to 2 7\/8\" wide gets one mounting flange, as wide as the pocket.\u003c\/li\u003e\n  \u003cli\u003eA joist from 3\" up gets two flanges, each 1 1\/2\" wide.\u003c\/li\u003e\n  \u003cli\u003eFrom 4\" up, the two flanges are 2\" wide.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe pocket itself is 1\/16\" wider than your joist. The configurator opens on a 4\" joist in a hanger 7\" tall, with 2 1\/2\" beam flanges and 3\/8\" fasteners.\u003c\/p\u003e\n\u003ch2\u003eWhere the holes are\u003c\/h2\u003e\n\u003cp\u003eEach mounting flange has its holes down its centerline, and each beam flange has them 1\" from its free edge. A flange gets two holes, one high and one low, plus a third in the middle when the hanger is taller than 6\". None of the sizes limits another here, so the configurator has no spacing rule to enforce.\u003c\/p\u003e\n\u003ch2\u003eQuestions\u003c\/h2\u003e\n\u003ch3\u003eHow big does the groove in the joist need to be?\u003c\/h3\u003e\n\u003cp\u003eBig enough to clear whatever stands proud of the mounting flanges: the bolt heads or nuts, and any washers. That depends on your fasteners, so pick them first and measure them.\u003c\/p\u003e\n\u003ch3\u003eDoes any steel still show?\u003c\/h3\u003e\n\u003cp\u003eYes. The two beam flanges show along the joist's sides, with their fasteners, and the seat shows underneath. Only the mounting flanges and their fasteners are out of sight.\u003c\/p\u003e\n\u003ch3\u003eWhat if my joist is wider than 10\"?\u003c\/h3\u003e\n\u003cp\u003eUse the \u003ca href=\"\/pages\/contact-us#quote\"\u003equote form\u003c\/a\u003e to send the joist's size and how it meets the header.
