Metal Door Head","description":"\u003cp\u003eThe head is the horizontal top member of a knock-down hollow metal door frame, spanning between the two jambs to close the opening at the top and carry the frame's stop and soffit profile across it. It is formed from sheet steel with the same profile as the matching jamb legs, so the stop, rabbet and backbend line run continuously around the opening once the frame is assembled.\u003c\/p\u003e\n\u003cp\u003eKnock-down frame components ship flat and are joined on site, which lets the head be handled through finished corridors and set into an opening after the wall is framed. The head is tabbed or notched at each end to interlock with the jambs; the assembled frame is then plumbed, squared and anchored to the rough opening before the door is hung and the strike and closer hardware are fitted.\u003c\/p\u003e\n\u003cp\u003eThe 6-1\/8 in. dimension is the frame throat, which matches the wall thickness it straddles, and the 36 in. dimension corresponds to the door width the head spans.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHead member for a knock-down hollow metal door frame, matching the jamb profile\u003c\/li\u003e\n\u003cli\u003eFormed sheet steel construction with integral stop and soffit\u003c\/li\u003e\n\u003cli\u003eThroat dimension sized to straddle the finished wall thickness\u003c\/li\u003e\n\u003cli\u003eEnds prepared to interlock with the frame jambs for on-site assembly\u003c\/li\u003e\n\u003cli\u003eShips flat for handling through finished openings and corridors\u003c\/li\u003e\n\u003cli\u003eAccepts standard frame anchors and can be finished with field-applied paint over the factory prime\u003c\/li\u003e\n\u003cli\u003eSold individually as a replacement or made-up component\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAssembling knock-down hollow metal door frames in stud or masonry openings\u003c\/li\u003e\n\u003cli\u003eCommercial corridor, stair and utility room doors\u003c\/li\u003e\n\u003cli\u003eBasement, boiler room and mechanical space entries\u003c\/li\u003e\n\u003cli\u003eReplacing a damaged head on an existing hollow metal frame\u003c\/li\u003e\n\u003cli\u003eMultifamily and institutional interior openings where a steel frame is specified\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 Hollow metal door frame head\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Formed sheet steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Construction:\u003c\/strong\u003e Knock-down, field-assembled\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Width:\u003c\/strong\u003e 36 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThroat Depth:\u003c\/strong\u003e 6-1\/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\u003e36\" x 6-1\/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":55112703213907,"sku":"MDH36618","price":30.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1012\/7743\/4195\/files\/36-in-x-6-1-8-in-metal-door-head-mdh36618.webp?v=1790734584","url":"https:\/\/arch-9365.myshopify.com\/zh\/products\/36-in-x-6-1-8-in-metal-door-head-mdh36618","provider":"ARCH","version":"1.0","type":"link"}
