An adjustable bar hanger is a metal hanger designed to fit varying distances between floor and ceiling joists or rafters. It is used to securely hold electrical outlet boxes and devices in place, providing a flexible and stable mounting solution.

Purpose

The purpose of an adjustable bar hanger is to facilitate the secure and precise installation of electrical outlet boxes and devices between structural members such as joists or rafters. Its adjustable nature allows it to accommodate different spacing configurations, making it a versatile tool for electricians during new construction or renovation projects. This ensures that electrical boxes are properly positioned and supported, contributing to the safety and reliability of electrical systems.
