Grisham AWG Fixed Window Security Bars – Black

The Grisham AWG Fixed Window Security Bars provide a non-egress option suitable for homes with emergency exit plans in place. These bars are built from heavy-duty tubular steel and use a robotic welding process to ensure 100% intact solder joints. They support inside or outside mounting with tamper-proof one-way screws, and installation screws are included. While not intended for sleeping quarters without alternate exits, the design emphasizes burglar resistance and child safety in common living areas.
Grisham AWG Fixed Window Security Bars – White

This white variant mirrors the black Grisham design with heavy-duty tubular steel and a robust welding process. It is suitable for interior or exterior mounting and ships with tamper-proof one-way installation screws. The non-egress design prioritizes child safety and window security in non-bedroom areas where an alternate egress exists.
Segal S 4768 Carbon Steel Fixed 4-Bar Window Grill

This fixed window guard uses 0.048-inch-thick white carbon steel square tubing to form a security grate with 3-7/8 inch bar spacing. It’s designed for interior use and features adjustable width from 32-1/2″ to 54″, enabling fitment across various window sizes. It offers a non-egress design, preventing quick removal in emergencies, and includes one-way, tamper-proof installation screws for secure mounting. Ideal for homes prioritizing child safety in living spaces.
Prime-Line S 4767 Carbon Steel Fixed 4-Bar Window Grill

Prime-Line’s fixed four-bar grill, finished in black, uses 0.048 inch thick carbon steel and provides reliable child-safety protection. It features a fully adjustable width from 32-1/2″ to 54″ with included one-way, tamper-proof screws. The non-egress design ensures the bars cannot be opened from the inside, making it a solid option for interior installations where emergency access is preserved via other exits.
Buying Guide: Key Purchase Considerations
- Application and egress: If emergency escape is a concern, choose non-egress bars for safety and select hinged or separate exit mechanisms for quick access in emergencies. Always verify local building codes and safety requirements.
- Material and finish: Tubular steel and carbon steel are common choices for durability. Powder-coat or electrostatic finishes (e.g., black, white) resist rust and weathering in exposed areas.
- Adjustability and fit: Look for adjustable widths that cover the target window size, with clear mounting instructions. A wider adjustment range reduces the number of parts and installation complexity.
- Mounting method and screws: Tamper-proof or one-way screws deter tampering. Confirm whether installation is interior, exterior, or both, and ensure screw heads won’t damage window frames.
- Security vs. aesthetics: Some designs are more visually integrated with window frames. Consider color and style that complement home exterior and interior decor while meeting security needs.
- Installation effort: Check for included hardware and whether installation requires professional tools or services. Fully pre-drilled and guided mounting can simplify setup.
- Maintenance: Choose corrosion-resistant materials and easy-clean finishes to minimize upkeep and longevity in varied climates.
- Child safety: For households with young children, evaluate bar spacing (typically around 3.75 inches on center) to prevent climbing and accidental falls.
These selections provide a balance of security features, ease of installation, and interior/exterior compatibility. When selecting a product, consider the window size, the emergency egress requirements of your home, and whether you prefer a unified appearance or a more utilitarian look to fit your space.
