Security

Bristol’s patented Q-IV security locking system provides maximum safety levels without purchasing a costly security system.

Windows that include a “Quattro IV Security System”, are designed to deter residential forced entries/burglaries through properly locked windows and doors by increasing the difficulty level of entry. From the exterior the Q-IV locking handle is not visible and therefore not operable.

The Q-IV systems, as any other system on the market, cannot ever make a residence 100% forced entry/burglary-proof. Proper use of a Q-IV Security System should discourage attempts of forced entries/burglaries. Windows with Q-IV systems offer an exclusive 50-year security guarantee.
An additional ventilation lock with a steel concealed spring provides a sense of security while allowing ventilation into the room.
