Metal Door Frame Head","description":"\u003cp\u003eThe head is the horizontal member that spans the top of a knock-down hollow metal door frame, tying the two jambs together and forming the upper rabbet the door closes against. It arrives as a separate piece so the frame can be carried into place flat and assembled around a finished opening rather than set before the walls close up.\u003c\/p\u003e\n\u003cp\u003eLike the jambs it mates to, the head is roll-formed steel with a returned stop and soffit, notched and tabbed at each end so it locks to the jamb legs and squares the assembly. The throat dimension is sized to the wall it wraps, so the head must match the jamb depth of the frame it is being fitted to.\u003c\/p\u003e\n\u003cp\u003eHollow metal heads are used with commercial hollow metal or wood doors and are typically finished with a factory prime coat ready for field painting.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHorizontal head member for a knock-down hollow metal door frame\u003c\/li\u003e\n\u003cli\u003eRoll-formed steel with integral stop and soffit forming the top rabbet of the opening\u003c\/li\u003e\n\u003cli\u003eNotched and tabbed ends interlock with matching jamb legs for square assembly\u003c\/li\u003e\n\u003cli\u003eThroat depth sized to the wall assembly it wraps\u003c\/li\u003e\n\u003cli\u003eKnock-down design allows installation around an existing finished opening\u003c\/li\u003e\n\u003cli\u003eTypically supplied with a factory prime coat for field painting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eReplacement or repair of a damaged hollow metal frame head\u003c\/li\u003e\n\u003cli\u003eAssembling knock-down steel frames in drywall partitions\u003c\/li\u003e\n\u003cli\u003eCommercial corridor, stair and utility room door openings\u003c\/li\u003e\n\u003cli\u003eTenant fit-outs and renovation work where frames are set after walls are finished\u003c\/li\u003e\n\u003cli\u003eOpenings using hollow metal or wood commercial doors\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Metal door frame head\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpening Width:\u003c\/strong\u003e 30 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJamb Depth:\u003c\/strong\u003e 4-7\/8 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As:\u003c\/strong\u003e Each\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable class=\"product-specs\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eDimensions\u003c\/th\u003e\n\u003ctd\u003e30\" x 4-7\/8\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"ARCH Building Supply","offers":[{"title":"Default Title","offer_id":55112702656851,"sku":"MDH30478","price":30.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1012\/7743\/4195\/files\/30-in-x-4-7-8-in-metal-door-frame-head-mdh30478.webp?v=1790734577","url":"https:\/\/arch-9365.myshopify.com\/zh\/products\/30-in-x-4-7-8-in-metal-door-frame-head-mdh30478","provider":"ARCH","version":"1.0","type":"link"}
