Buying Guide: Key Purchase Considerations
- Door clearance: Most locks require a minimum gap (commonly 0.46 inches / 1.17 cm). Measure before buying to ensure compatibility with your door and frame.
- Adhesive vs. mechanical: Adhesive-based options are quick to install and non-invasive, but may require longer cure times to maximize strength. Mechanical or hinge-style locks may offer more robust security but could require drilling or mounting hardware.
- Two-handed operation: Locks that require pressing two buttons or squeezing components can deter toddlers from opening. Consider child-proof designs that balance safety with ease of adult use.
- Visibility: Crystal-clear or low-profile designs blend with glass surfaces, reducing visual intrusion while maintaining security.
- Multi-surface compatibility: Look for products that fit sliding doors, windows, patios, closets, and cabinets to cover multiple openings in a single purchase.
- Removability and residue: Adhesive locks should be removable without surface damage if you plan to relocate or remove them later.
- Strength and durability: Choose locks tested to withstand daily pulling forces and consider materials like ABS or durable plastics for long-term use.
