What is the standard thickness of a trap door for a stage?

The standard thickness of a trap door for a stage is typically 1.5 inches. This thickness provides a balance of durability and manageability. A trap door must be sturdy enough to support the weight of performers and equipment while also allowing for ease of movement during productions. In stage settings, where both safety and functionality are paramount, 1.5 inches is considered appropriate to achieve these needs without being excessively cumbersome or heavy. This thickness helps ensure that the door can withstand the stresses of frequent use, while also fitting well within the design parameters of stage construction and safety codes.
