TESTED PERFORMANCE

Heavy impact: withstands 100 ft-lbs of force without stretching the screen material beyond 3" or tearing the mesh
Forced entry: resists a 150 lb prying load plus a simultaneous 300 lb pulling load without frame bending or lock failure
Sag test: holds a 90 lb weight on an open screen with a maximum of .063" sag

The heaviest-gauge window screen Rusco builds, purpose-built for high-risk security areas

Backed by documented impact, forced-entry, and sag test results, not just a duty-tier label

Same custom-fit, non-square-capable construction as every Rusco security product
