This lock ships less cylinder, meaning the end user or installing locksmith supplies the cylinder to match the existing keying system. The L lever trim and LN rose configuration provide a clean, functional profile suited to high-traffic openings. The unit is field reversible, allowing installation on doors with either a left-hand or right-hand swing without special-ordering a handed version. The satin chrome (26D) finish offers a low-glare, corrosion-resistant surface appropriate for institutional environments.\u003c\/p\u003e\n\u003cp\u003eClassroom security intruder locks are specifically designed to lock from the outside using a key while keeping the lever freely operable from the inside, allowing occupants to shelter in place without unlocking the door. This function is widely specified in K-12 schools, universities, government buildings, and healthcare facilities where PASS (Prevent, Avoid, Secure, Survive) lockdown protocols are required. The ASA strike included with this unit is compatible with standard mortise door preparations and works with hollow metal or solid wood door frames common in commercial construction. A licensed locksmith or credentialed door hardware installer typically handles the final cylinder prep and keying.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n \u003cli\u003eGrade 1 ANSI\/BHMA commercial duty rating for high-cycle, high-traffic applications\u003c\/li\u003e\n \u003cli\u003eClassroom security intruder function: outside lever locks by key while inside lever remains free at all times\u003c\/li\u003e\n \u003cli\u003eShips less cylinder, allowing field integration with existing master key systems\u003c\/li\u003e\n \u003cli\u003eField reversible design eliminates the need to specify hand of door at time of order\u003c\/li\u003e\n \u003cli\u003eL lever with LN rose trim in satin chrome (26D) finish for institutional aesthetics\u003c\/li\u003e\n \u003cli\u003eASA strike included for compatibility with standard commercial door frames\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation mortise lock for commercial and institutional doors requiring classroom security intruder function with a standard mortise lock preparation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed locksmith or qualified door hardware technician familiar with commercial mortise lock preparations and applicable building codes. The door must be prepared with a mortise pocket that matches the lock body dimensions before installation. Because this unit ships less cylinder, the appropriate cylinder must be sourced and prep-cut to the correct keyway before the lock is placed into service. Verify that the door handing and frame strike alignment are confirmed before final fastening.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eLock Grade\u003c\/strong\u003e: Grade 1 (ANSI\/BHMA)\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eLock Function\u003c\/strong\u003e: Classroom Security Intruder Latchbolt\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eLock Type\u003c\/strong\u003e: Mortise\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eTrim Style\u003c\/strong\u003e: L Lever, LN Rose\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eHanding\u003c\/strong\u003e: Field Reversible\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eCylinder\u003c\/strong\u003e: Less Cylinder (field supplied)\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eStrike\u003c\/strong\u003e: ASA Strike Included\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Satin Chrome (26D)\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: SARGENT\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: LC-8238 LNL 26D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SARGENT","offers":[{"title":"Default Title","offer_id":68299346280754,"sku":"LC-8238 LNL 26D","price":874.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c6139f6267db8fca728fa78e8a643131_2f304a67-84e0-46cc-9953-f1e0a5a19e42.jpg?v=1793714496","url":"https:\/\/voomisupply.com\/products\/sargent-lc-8238-lnl-26d-mortise-lock-classroom-security","provider":"Voomi Supply","version":"1.0","type":"link"}
