Lokatall Black Window Sash Jammer
The Lokatall sash jammer provides a robust addition to UPVC or PVC doors and windows. It acts as a door stopper and window lock, designed to prevent lever attacks by strengthening the seam between the sash and frame. Constructed from sturdy zinc alloy, it resists rust and wear while delivering a clean, unobtrusive look that blends with most decor. A screw-reinforced back securely bonds the base to the locking arm, delivering a dependable barrier for entry points around homes and apartments. Easy to install on existing UPVC hardware, this two-pack option is a practical upgrade for multiple openings.
Prime-Line F 2588 Sash Lock
This Prime-Line sash lock is designed for vertical sliding vinyl windows and features 2-1/16 inch center mounting holes on both lock and keeper. It mounts to the check rails of single and double hung sash windows, with a cam-type locking mechanism that pulls the rails together for a tighter seal. The result is improved security and added wind/storm protection. It is a practical replacement part for worn or damaged locks and is compatible with many aluminum and vinyl window configurations, supporting both security and energy efficiency.
FABULETTA Aluminum Alloy Window Restrictor Lock (Black)
FABULETTA’s restrictor lock uses high-strength aluminum alloy to deter burglars by preventing lever-free unlocking. Its anti-levering design locks the window handle firmly in place, helping to deter intruders while maintaining a straightforward installation process. The product aims to offer reliable security without extensive modifications to existing UPVC sash setups, making it suitable for homes and small offices. The black finish blends with dark frames and modern hardware, providing a discreet security upgrade for residential windows.
EMASDGEY Secure T Shaped Blocker
EMASDGEY offers a T-shaped blocker designed for UPVC doors and windows, with a focus on simple installation and robust mounting. The product’s alloy construction emphasizes durability while providing a straightforward securing mechanism for residential use. The design supports residential and small commercial settings, helping prevent unwanted access to sashes and improving overall window security. The locking arrangement integrates with standard frames, reducing the need for heavy modification during setup.
eSynic 6-Pack Window Restrictor Locks
eSynic’s six-pack restrictor locks provide heavy-duty security for UPVC windows. The aluminum alloy base supports durability in high-use environments, and the set offers multiple units for securing several openings across a home or office. The product emphasizes anti-burglary performance, working to deter intruders by limiting window reach while preserving accessibility for occupants in emergencies. The included hardware and straightforward installation simplify retrofitting across multiple windows at once.
Buying Guide: Key Purchase Considerations for UPVC Sash Security
- Security level: Consider anti-levering features, strength of materials (aluminum alloy, zinc alloy), and whether a key-controlled option is needed for added control and accountability.
- Window compatibility: Check mounting hole centers and rail types (single/double hung, vinyl, or aluminum) to ensure compatibility with your UPVC sash configuration.
- Installation complexity: Look for products with simple mounting, included screws, and minimal frame modification. Self-tapping screws and clear instructions speed up the process.
- Aesthetic fit: Choose finishes (black, white, or metallic) that complement your window frames and hardware for a seamless appearance.
- Maintenance and durability: Preference for rust-resistant materials (zinc alloy, aluminum) helps ensure long-term performance in varying climates.
- Emergency access: If you require quick egress, consider restrictors with keys or easy-release mechanisms that balance security with safety.
- Number of openings: For homes with multiple UPVC openings, pack sizes (like 2-pack or 6-pack options) influence overall cost-effectiveness and installation coverage.
When selecting UPVC sash window security devices, it is important to balance robust protection with ease of use and compatibility with existing hardware.
