In duct work, from where should the steel line exit?

Explanation:
The best exit point is the center of the duct. Exiting from the center gives the steel line the most uniform clearance on all sides, reducing the chance that the pipe will rub against duct walls or be stressed by duct movement. It also makes it easier to insulate and seal around the penetration and provides a stable, balanced route for support and alignment. Exiting from the top, bottom, or side can place the line closer to a wall or joint, increasing the risk of damage, twisting, or improper sealing and complicating installation.
