Zero Automatic Drop Seals

half-365A

Drop seals fit to the bottom of a door and drop down automatically when the door closes to form a tight seal.

Most Zero drop seals (or automatic threshold seals) are adjustable to 25mm. They work on a hinge-side plunger with a flat spring mechanism, so there are no electrics to deal with. The system drops a neoprene gasket in a scissor-like motion to form a tight seal with no drag – even on an uneven floor. The seal retracts automatically when the door opens.

HOW ZERO DROP SEALS WORK

All our drop seals work in the same way: they activate on the hinge-side first to prevent the seal from dragging when the door closes. This avoids door hang-up or delays in closing. The low-force system is self-levelling and does not conflict with the lock, latch or closing mechanism.

Zero drop seals also provide added security. By eliminating the gap beneath a door, you’re reducing the chance that criminals could exploit this weakness.

Consider a drop seal if you need to seal a door against any of the following:

•   Draughts
•   Weather
•   Noise
•   Fire
•   Light
•   Smoke
•   Odours
•   Fumes
•   Insects
•   Rodents and other vermin

Our clients have used our drop seals very effectively in these environments:

•   Building entrances
•   Entertainment venues
•   Broadcasting
•   Travel hubs
•   Industrial settings
•   Medical facilities
•   Business premises
•   Education establishments
•   Public buildings
•   Interview rooms
•   Research facilities
•   Leisure centres
