Every 25 Seconds,
a US Home Is
Burglarized.
Burglars choose homes without visible barriers 3× more often. Ground floor windows are the #1 entry point — yet most homeowners do nothing until after a break-in.
85% of opportunistic burglars abandon an attempt within 60 seconds if they can't get through. Window bars make your home a hard target.

Designed specifically for masonry, stucco, and irregular wall surfaces. The Model B brings the same telescopic + modular system with enhanced wall-anchor hardware.
Model A/EXIT
Quick-Release Fire-Safe Window Bar

“We heard noises in the middle of the night. Our cameras showed two people trying to force a window. Thanks to the SWB bars, they couldn't get in and police arrived in time. I can't imagine what would have happened without them.”
“I installed all six windows in an afternoon — took me maybe 3 hours total. The design is clean, doesn't look like a prison at all. My neighbors actually asked me who did it, they thought it was a contractor.”
“After my neighbor's break-in I couldn't sleep. Had SWB bars on all my ground-floor windows in a weekend. The Model A/EXIT in my bedroom means I'm protected AND my family can still get out in an emergency. Peace of mind, finally.”
