A new threshold raises the floor and the bathroom door drags during operation. What should be verified?

Correct Answer

C) The door’s operating clearance at the new threshold.

Check the slab’s operating clearance relative to the finished threshold and floor. Correct the installation within the door’s applicable limits rather than automatically cutting a rated or special-purpose door. Source: https://www.jeld-wen.ca/Articles/projects/replacing-exterior-doors

Answer Options

Only the previous threshold height, ignoring the new installation.

The door’s operating clearance at the new threshold.
