The housing is cast from Zamak, a durable zinc-based alloy, and paired with an aluminum bolt. It installs onto the lower back-edge of the sash or door frame and provides an added layer of security when a window or door is held partially open for ventilation or locked fully closed. The bolt delivers a 1\/2 inch reach, the body stands 11\/16 inch tall, and mounting hole centers are spaced 1-5\/8 inches apart. Installation requires minor drilling. Glaziers, window installers, and general contractors typically handle this type of hardware.\u003c\/p\u003e\u003cp\u003eThe MP4002 is suited for residential and light-commercial applications where sliding windows or patio doors need secondary security beyond the primary latch. It is commonly used as a retrofit or replacement lock on existing horizontal sliding window units and sliding patio door systems. The zinc finish blends with standard aluminum and vinyl window hardware. Because it functions as a secondary device, it can be engaged at a partially open position to allow controlled ventilation while limiting intrusion risk.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTwist-in action allows quick engagement and release without tools\u003c\/li\u003e\n\u003cli\u003eZamak cast housing provides rigid, corrosion-resistant support\u003c\/li\u003e\n\u003cli\u003eAluminum bolt with 1\/2 inch reach for positive stop engagement\u003c\/li\u003e\n\u003cli\u003e11\/16 inch body height fits within standard sash and door frame profiles\u003c\/li\u003e\n\u003cli\u003e1-5\/8 inch mounting hole centers for straightforward alignment during install\u003c\/li\u003e\n\u003cli\u003eZinc finish compatible with common aluminum and vinyl window hardware finishes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on horizontal sliding windows and patio sliding door systems as a secondary security locking device.

Power down any automated door systems before beginning work. Use a properly sized drill bit to align with the 1-5\/8 inch mounting hole centers and ensure the bolt path is clear before securing the housing. Do not overtighten fasteners into the Zamak housing, as the material can crack under excessive torque.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Reach\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Height\u003c\/strong\u003e: 0.6875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Hole Centers\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Package Dimensions\u003c\/strong\u003e: 3.11 inches x 4.02 inches x 0.98 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing Material\u003c\/strong\u003e: Zamak (zinc-based alloy cast)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAction Type\u003c\/strong\u003e: Twist-in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity\u003c\/strong\u003e: Single pack\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PRIME-LINE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MP4002\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRIME-LINE","offers":[{"title":"Default Title","offer_id":52080592617778,"sku":"MP4002","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/77d2a92a985e41360f80b979a83f8d5a.jpg?v=1790055663","url":"https:\/\/voomisupply.com\/products\/prime-line-mp4002-twist-in-sliding-door-window-lock","provider":"Voomi Supply","version":"1.0","type":"link"}
