• Size & Compatibility: 2.18 in (54mm) center-to-center mounting hole spacing; fits left- or right-opening installations on vertical and horizontal sliding windows—please verify dimensions before purchase.
• Enhanced Window Security: Helps prevent forced entry and reduces the risk of accidental window opening—ideal for improving home safety on sliding and double-hung windows.
• Cam-Action Tight Locking Design: Cam hook pulls the keeper tight when locked for a secure hold; anti-jimmy studs engage with the keeper to resist prying.
• Heavy-Duty Metal Construction: Zinc alloy die-cast body with multi-layer electroplating for high hardness, wear resistance, corrosion resistance, and rust protection (more sturdy than plastic locks).
• Easy Installation Kit Included: Comes with 10 window sash locks and stainless steel screws; install with a screwdriver (recommended 3 mm pre-drill). For narrow window edges under 0.31 in (8 mm), use a compatible square hook and secure with screws as needed.
