In theatre, a carpenter is a stagehand who builds sets and stage elements.
[1] They usually are hired by the production manager, crew chief or technical director.
Working mainly with woods and metals, they use techniques that include woodworking and welding.
For example, a carpenter may be responsible for building stairs and ramps on and off of the performance area and for leveling the stage floor itself.
Only carpenters trained as riggers are trusted to do rigging (see fly crew).
