STJH-AUTOMATIC-DOOR-DROP-SEAL-MORTISED-SLIM
Automatic Door Drop Seal Slim Mortised
Close the door-bottom gap with a slim seal that retracts automatically when the leaf opens.
- Fully mortised installation hides the carrier.
- Self-levelling action accommodates small floor variations.
- Mechanical operation avoids a separate electrical supply.
Product Introduction
The slim carrier fits fully inside a prepared groove at the bottom of a metal or aluminum-compatible door leaf. A mechanical plunger contacts the frame during closure and lowers the sealing element toward the floor. Opening the door releases that action so the seal rises clear. The concealed arrangement preserves the visible door faces and provides a moving bottom seal without introducing a powered actuator or a permanently dragging strip.

- Fully mortised installation hides the carrier.
