This extension piece mounts between the door closer and the electromagnetic armature, providing the additional standoff distance required when standard mounting geometry does not achieve proper magnet-to-armature contact. Finished in 689 Aluminum, it coordinates with aluminum-finish door hardware commonly specified in commercial and institutional openings. Installation is handled by licensed door hardware technicians or qualified commercial contractors working on low-voltage electromagnetic closer systems.\u003c\/p\u003e\n\u003cp\u003eThis magnet extension is suited for commercial door openings in high-traffic facilities including schools, hospitals, government buildings, and correctional facilities where electromagnetic hold-open door closers are installed. It is used when the door or frame geometry requires additional projection to ensure consistent magnet engagement. The 689 Aluminum finish makes it appropriate for aluminum storefront and hollow-metal frame applications where finish matching is required by specification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-inch extension provides additional standoff for proper magnet-to-armature alignment\u003c\/li\u003e\n  \u003cli\u003e689 Aluminum finish coordinates with standard aluminum door hardware specifications\u003c\/li\u003e\n  \u003cli\u003eCompact form factor at 4.88 inches length by 3.94 inches width by 1.89 inches height\u003c\/li\u003e\n  \u003cli\u003eLightweight construction at 0.5 pounds for easy handling during installation\u003c\/li\u003e\n  \u003cli\u003eDesigned for use in high-traffic institutional and commercial door openings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and accessory component for LCN electromagnetic door closer systems requiring a 2-inch magnet extension in 689 Aluminum finish.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified door hardware technician or commercial contractor familiar with electromagnetic closer systems. Disconnect and de-energize the electromagnetic hold-open circuit before beginning any work on the closer or armature assembly. Verify that the extension achieves full, flush magnet-to-armature contact before restoring power and testing hold-open function. Local building and fire codes may govern the use of hold-open door closers in rated corridor and egress applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtension Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: 689 Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 4.88 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 3.94 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 1.89 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\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: LCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SEM7810E200AL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LCN","offers":[{"title":"Default Title","offer_id":51557995839794,"sku":"SEM7810-E200 AL","price":57.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310050979.png?v=1786400404","url":"https:\/\/voomisupply.com\/products\/lcn-sem7810e200al-magnet-extension-689-aluminum","provider":"Voomi Supply","version":"1.0","type":"link"}
