ZERO is great door and window gasketing, great weatherstripping – and a great deal more. Our family of companies offers an unequaled range of integrated technologies and expertise. All from a single source…all in-house.

• Zero’s patented automatic door bottom technology ensures an efficient seal against the floor or saddle
• As the door is closed, the adjustable plunger is compressed against the door frame, activating a concealed flat spring mechanism
• This mechanism drops the seal smoothly from the housing in a scissor-like motion
• The door seal compresses on either even or uneven surfaces and retracts automatically when the door is opened
• Zero door bottoms are designed to block penetration by air, sound, smoke and flames
