It is configured with a 2-3\/8 inches backset and mounts on a square rose. This set suits doors ranging from 1-1\/4 inches to 2 inches in thickness. Door hardware installers and finish carpenters typically specify this type of lever for hallways, closets, and common-area interior openings where entry control is not required. The Flat Black finish provides a consistent aesthetic across modern and transitional interior designs.\u003c\/p\u003e\n\u003cp\u003eThis passage lever is intended for interior residential or light commercial doors. It is suited for hallway and closet applications where a latch is needed but a lock cylinder is not. The square rose backplate provides a clean, geometric mounting profile. The 2-3\/8 inches backset is standard for most interior door prep, and the door thickness range of 1-1\/4 inches to 2 inches covers the majority of residential hollow-core and solid-core interior doors.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePassage function — no lock cylinder, latch operation only\u003c\/li\u003e\n  \u003cli\u003eRight-hand orientation for proper lever return\u003c\/li\u003e\n  \u003cli\u003e2-3\/8 inches backset fits standard interior door prep\u003c\/li\u003e\n  \u003cli\u003eSquare rose backplate for a geometric, modern profile\u003c\/li\u003e\n  \u003cli\u003eFlat Black finish suited for contemporary and transitional interiors\u003c\/li\u003e\n  \u003cli\u003eCompatible with door thickness from 1-1\/4 inches to 2 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style passage lever replacement or new installation for interior doors with a standard 2-3\/8 inches backset prep and door thickness between 1-1\/4 inches and 2 inches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a finish carpenter, locksmith, or experienced installer. Confirm door hand orientation before mounting — right-hand designation affects lever return direction. Use the appropriate latch bolt for a 2-3\/8 inches backset and verify door thickness is within the 1-1\/4 inches to 2 inches range before ordering. No electrical shutoff is required; ensure the door is free-swinging and the latch bore and cross-bore are correctly prepared to the manufacturer's specified dimensions prior to installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBackset\u003c\/strong\u003e: 2-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDoor Thickness Range\u003c\/strong\u003e: 1-1\/4 inches to 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFunction\u003c\/strong\u003e: Passage\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRose Style\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Flat Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 8.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 7.3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.9 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSales Unit\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: EMTEK\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5110HLOUS19RH\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EMTEK","offers":[{"title":"Default Title","offer_id":51541484437810,"sku":"5110HLOUS19RH","price":146.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d263ef7bc66658e6536d90596acf9a53_0428d60c-d3fc-4734-ab36-1a72964081bc.jpg?v=1785877486","url":"https:\/\/voomisupply.com\/products\/emtek-5110hlous19rh-helios-lever-passage-set-flat-black","provider":"Voomi Supply","version":"1.0","type":"link"}
