Blocking is a fundamental carpentry technique where pieces of wood are installed between wall studs, joists, or rafters to provide additional support and mounting points. Think of blocks as extra pieces of wood that create a sturdy backing for hanging heavy items, supporting structures, or reinforcing corners. When a job description mentions blocking, it typically refers to this reinforcement process that's essential for proper construction and safety. Similar terms you might see include "backing," "nogging," or "bridging."
