The clearance between the bottom of a swing door and the sill must not exceed?

The specified maximum clearance between the bottom of a swing door and the sill being 3/8" is important for several reasons. Firstly, this clearance is designed to prevent debris from entering the elevator shaft, which can interfere with the operation of the elevator and contribute to safety hazards. A clearance that is too large may allow dust, dirt, and potentially harmful objects to accumulate, leading to maintenance issues and safety concerns for users.

Additionally, maintaining a 3/8" clearance ensures proper sealing and performance of the elevator doors. This dimension is often stipulated in elevator code requirements and industry standards to ensure that the doors close effectively, reducing drafts and enhancing energy efficiency.

Moreover, adhering to this clearance specification helps in user accessibility by preventing trip hazards and ensuring smooth operation of the door mechanism. Overall, the 3/8" clearance standard is a crucial component in ensuring the safe and efficient operation of swing doors in elevator systems.
