How do I know what size Security Window Bars to buy?

Measure the clear opening (width x height). Pick a telescopic height range, then add modules for width.

Can I install Security Window Bars myself?

Yes. SWB is DIY-friendly. Choose frame or wall-mount, use the supplied hardware, and follow the DIY Install Guide.

Do I need a quick-release for bedrooms?

If the window is a required emergency exit in your area, choose the Emergency-Exit model and test the release after install.

Frame or wall-mount — which is better?

Frame-mount is clean when jambs are square; wall-mount suits brick, block, and uneven frames.

What if my sliding window is really wide?

Use modules to reach spans up to approximately 79 inches, or run two adjacent assemblies.

Interior or exterior install?

Both work. Interior simplifies quick-release access; exterior adds street-side deterrence.

Are Security Window Bars safe for children?

Yes, Security Window Bars are an excellent option to protect children near windows. Always supervise children near windows.

How can I expand the Security Window Bars in width?

Security Bars can be expanded in width by adding modules. This allows for greater customization and adaptation to any window size.

What is the recommended distance between modules?

We recommend approximately 4 inches between modules. This ensures safe, effective installation and allows bars to expand correctly.
