Nominal size is the size of the door without undercut. Exact size is the size of the door with undercut applied. Understanding the difference between nominal and exact dimensions is essential for ordering the correct commercial door and frame assembly. This reference guide explains the CDF Distributors model numbering system, undercut dimensions, and how nominal sizes translate to exact measurements for standard commercial doors.
CDF Distributors’ ProBuilder tool at cdfdistributors.com displays both nominal and exact dimensions for every door and frame configuration. For assistance with door sizing or ordering, call (855) 769-9895 or email sales@cdfdoors.com.
CDF Model Numbering System
CDF door and frame model numbers use feet, not inches. This is a common source of confusion when reading specifications or placing orders. A model number consists of two pairs of digits representing the width and height in feet.
- 3070: 3’ wide x 7’ tall (not 30 inches x 70 inches)
- 3080: 3’ wide x 8’ tall
How Lockdown Hardware Selection Affects AHJ Approval and Campus Security
This guide answers: How School Door Hardware Selection Affects Lockdown and AHJ Approval
How Hardware Selection Affects Lockdown Capability
The selection of door hardware for K-12 schools directly determines whether a facility can execute an effective lockdown. Hardware that does not meet classroom security function requirements — or that requires a teacher to open the door, reach into the corridor, and use a key — creates a critical delay during an active threat event.
The Authority Having Jurisdiction (AHJ) reviews hardware selections during the plan review and inspection process. Hardware that does not satisfy the jurisdiction's lockdown requirements will be rejected, requiring replacement at the contractor's expense.
Classroom Function vs. Classroom Security Function
Standard classroom function locksets require the teacher to use a key from the corridor side to lock the door. This means the teacher must open the
A door that swings freely might seem harmless until it slams shut in a hallway, lets drafts sneak in, or leaves your office vulnerable during an emergency. A door closer is more than just a spring-loaded gadget, but works to ensure your doors close properly every time.
Installing the right door closer can transform a simple doorway into a shield against fire hazards and energy loss. The right closer can protect your employees, visitors, and property while enhancing convenience and efficiency. So are door closers necessary, and if so, how? Let’s explore how they benefit your office.
Understanding Office Door Closers
A door closer is a mechanical device that automatically closes a door after it has been opened. They help the doors open more easily and ensure they won’t create a barrier. While it may seem minor, the benefits go beyond convenience:
-
Ensures doors close securely to prevent unauthorized access.
-
Helps maintain climate control and reduce energy costs.
-
Reduces wear and tear on hinges
When you think of doors, you probably picture wood, metal, or glass simply marking the entryway into a space. But doors can be so much more, and they can actually be

When customers walk into your store, the first thing they see isn’t the display shelves or your front desk, it’s the doorway that welcomes them in. Your storefront doors are more than just an entrance, they provide safety in emergencies and can even help shape your brand’s image.
In short, the right commercial door does more than open and close, but it can protect, secure, and impress all at once. So, how do you make sure your storefront doors are working as hard as you are? Let’s explore the different ways to maximize security and safety without compromising on style.
Choosing the Right Door
Not all doors are created equal. A lightweight or poorly constructed door can be an easy target for intruders. For maximum protection, invest in commercial steel doors that offer durability, fire resistance, and superior strength. Pairing the right frame with the right door also ensures your entryway can handle heavy foot traffic.
However, steel doors can be more expensive than other types of doors,
Navigating the world of commercial doors can feel overwhelming. Knowing the type of doors you need, whether it’s steel doors, wood doors, or fire-rated doors, and what the required measurements and specifications are, can add up quickly.

When selecting doors for a building project, it’s important to look beyond appearance and consider functionality and long-term value. One of the key decisions involves choosing between solid core and hollow core doors. Each option offers distinct advantages and drawbacks that can affect durability, sound control, security, and cost.
Solid Core Doors
Solid core doors are made from engineered wood or particleboard filled to create a dense, sturdy interior. These doors provide a substantial feel, excellent sound insulation, and enhanced durability.
Pros of Solid Core Doors
When it comes to doors, solid core options are often seen as the premium choice, and for good reason, which includes:
-
Durability: Solid core doors are built to last and rarely get damaged. This makes them ideal for high-traffic areas in both residential and commercial settings.
-
Soundproofing: Due to their weight and solid structure, these doors offer excellent sound insulation. They reduce noise between office spaces
When you think of your building's security, what comes to mind? Chances are, it's not the door standing silently at the entrance. But perhaps it should be. Commercial steel doors are the unsung heroes of modern architecture, offering unparalleled strength and resilience. Let's delve into why these doors are more than just entry points.
Steel Doors for Every Commercial Space
When people hear “commercial steel doors,” their minds often jump straight to the classic double doors with push bars, functional, yes, but hardly the only option. The truth is, steel doors come in different varieties.
Need an eye-catching entrance for your storefront? A steel-framed glass door can combine durability with style, giving your building a welcoming and professional look. But if you’re looking for interior double doors that also allow for airflow, then metal doors with built-in louvers are the right option. They provide the perfect balance of ventilation and security. No matter your doorway’s size, purpose,
In the world of fire protection, every detail counts. Fusible link louver doors are an often-overlooked yet crucial component in maintaining safety and compliance in commercial and industrial buildings.
The Power of a Fusible Link
A fusible link is a temperature-sensitive device designed to melt at a specific temperature. When exposed to heat, the link melts, triggering a mechanism that closes the louver blades, thereby sealing the opening and preventing the passage of smoke and flames.
There are mechanical fusible links that consist of two metal strips that separate when heated. Commonly used in fire doors, they provide a fail-safe mechanism to close doors automatically during a fire.
How Does a Fusible Link Louver Function?
Fusible link louver doors are designed to balance airflow with fire safety. Under normal conditions, the louvers allow air to circulate through a building, helping with ventilation in hallways, mechanical rooms, or utility spaces. However, the real purpose of the
Your storefront door is more than just an entryway and can protect your business against unauthorized access and potential threats. From high-traffic urban locations to smaller neighborhood stores, every commercial property faces unique security challenges.
A weak lock, worn hinges, or improperly maintained doors can turn even the safest-looking business into a target. That’s why it is important you understand proper door security, implement preventive measures, and stay vigilant.
Why Commercial Door Security Is Important
Poorly secured doors can make your property vulnerable to break-ins, theft, and even vandalism. So, strong door security isn’t just a precaution, but it’s a key part of your overall business strategy.
Investing in proper commercial door security also helps you comply with safety regulations and insurance requirements. Many insurance policies require businesses to implement reasonable security measures, including locks, reinforced frames, and access controls.
