S3™ Bolt & Keep for Hinge Side Security & Improved Sealing

Security - Positive Locking

The S3™ BOLT & KEEP acts to overcome inbuilt security weaknesses in modern age windows by using ASL (Anti-Slip & Lock) technology. Intruders use the void areas between the glass and the frame itself to lever the frame out of its channel.

The S3™ BOLT & KEEP manipulates the intruder?s strength so that it works against himself.

The S3™ BOLT & KEEP security features:

• The security features lie dormant until the window is under attack.
• Provides security on the hinge side of the window - an area that is over-looked except by thieves.
• On attempted forced entry the hook on the bolt engages in the cut out window in the receiver to form a strong metal to metal connection.
• The greater the pressure an intruder applies, the greater is the resulting resistance to forced entry.

Improved Comfort + Energy Saving

The S3™ BOLT & KEEP improves sash management and sealing by using AST (Advanced Sealing Technology)

The S3™ BOLT & KEEP sealing features:

• A patented sash guidance and locating system for improved window opening reliability and durability
• Adjustable compression features to optimise window gasket compression through the life of a window.
• Controls and balances compression of the window gasket enabling the exclusion of draughts and noise - the reason that most consumers invest in new windows and hardware but often their expectations are not met
• Reduces frame distortion and resulting draught.
• Reduces wear and tear on the hinges by acting as a guide on closure of the sash and thus relieving pressure on the hinge
