PDB drop seal vs traditional drop seals

 

The two key differences are the arm controlled mechanism and full aluminium sealing bar.

  • The arm controlled mechanism offers an unrivalled sealing pressure compared to traditional drop seals which use a flat spring mechanism originating from the 1970s.
  • The full aluminium sealing bar comprises a solid aluminium bar with rubber EPDM shrouding. This secures the entirety of the threshold gap, creating a market-leading sealed solution.
 

Why does the new patented arm-controlled mechanism matter?

 

The success of any drop seal is measured by the consistent, optimum downward sealing pressure it can generate.

In our experience, traditional flat spring mechanisms can prove problematic due to the variance in spring tension. There can also be issues with maintaining the optimum downward pressure over the performance life of the drop seal. This can lead to: the need for high door closing forces; an uneven seal coverage; and/or an actuator button indentation in the door jamb.

In comparison, the PDB drop seal provides a consistent, controlled, unilateral downward pressure across the entirety of the sealing bar.

Thanks to this unique controlled downward pressure, we are the only drop seal capable of incorporating a fully composite sealing bar of aluminium supported by EPDM rubber shrouding. This provides a market-leading, robust and resilient seal.

In addition, the PDB drop seal requires a very low closing force. Due to the arm controlled mechanism, the push back pressure on the actuator button is minimal. This ensures the door set maintains its optimum functionality.

 

 

What makes the PDB different?

  • A market first > full aluminium sealing bar for complete protection
  • Operates off globally patented arm-controlled mechanism.
  • Offers unique security benefit
  • Globally patented design
  • Select 32"or 36" length. May be trimmed down in length by as much as 4" on site without interfering with drop-bar mechanism.
  • Or you may specify custom length up to 28", and then specify in the notes section of your order the exact length you want
  • Also available in surface mounted version, please see PDB 411S for more information.
