• Simplicity: Crescent locks are known for their straightforward design and ease of operation.
• Common on Sliding Windows: They are a very prevalent locking mechanism for horizontal sliding windows, where the hook on one sash engages with a keeper on the other.
• Variety of Materials: They are typically made from materials like zinc alloy, aluminum alloy, stainless steel, or plastic, with various finishes available (white, black, chrome, etc.) to match the window or door.
• Locking and Non-Locking Options: Some crescent locks come with a key cylinder for added security, while others are simple latches without a key.
• Different Styles and Sizes: Crescent locks are available in various styles and sizes to suit different window and door designs. You might find single-point or multi-point locking versions.
