Delf’s Heavy Duty Roller Bolt is perfect for use in conjunction with Pull Handles and Deadbolts on a swing or Pivot style Front door.

This heavy duty roller bolt holds the door securely in a closed position, but allows the door to be opened by either pulling on a Handle or pushing the door.

With adjustable tension, it ensures the door is not allowed to blow open in the wind, whilst still allowing it to be opened with ease.
