Before you measure a door rough opening, there are several critical decisions that must be made first — and skipping this step is one of the most common causes of ordering mistakes in commercial door projects.

In this video from CDF Distributors, we walk through what needs to be determined before you ever pick up a tape measure so your door system is specified correctly the first time.

 

Why Preparation Matters Before Measuring


Most commercial door installation issues do not come from incorrect measuring — they come from incorrect planning.

Traffic flow, fire ratings, and building requirements must be determined before the rough opening is measured. Without these decisions, even a correctly measured opening can result in the wrong door system.

CDF Distributors helps contractors and builders avoid these issues by ensuring door specifications are correct before fabrication or installation begins.
