Choosing the wrong door frame can lead to expensive delays, failed inspections, and major rework on the jobsite—but it doesn’t have to. In this video, we break down how to choose the right commercial door frame so you can avoid costly mistakes before they happen.

Quick Answer: How Do You Choose the Right Commercial Door Frame?

Choosing the right commercial door frame depends on the wall construction, opening type, fire rating requirements, and installation method. The two most common commercial door frame types are welded frames and knockdown (KD) frames. Welded door frames are typically used for masonry walls, exterior openings, and high-abuse applications, while knockdown door frames are commonly used for drywall construction and interior commercial openings. Selecting the correct hollow metal door frame helps ensure proper installation, code compliance, long-term durability, and accurate door operation.

Commercial Door Frame Selection Checklist

Before ordering a commercial door frame, verify the wall type, wall thickness, door size, fire rating requirements, hardware preparations, and installation conditions. Contractors should also determine whether the opening requires a welded frame or knockdown frame and confirm frame dimensions match the rough opening. Following a commercial door frame checklist helps avoid specification errors, failed inspections, and delays during installation.
