Introducción del producto

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.
