Why CDF Sources Forte Opening Solutions for Fire-Rated Wood Doors
Forte Opening Solutions is CDF's primary vendor for fire-rated wood doors. When a project requires a wood door with a fire rating, CDF sources from Forte Opening Solutions to ensure the door meets all applicable listing requirements.
Forte Opening Solutions (formerly Masonite's commercial door division, rebranded in 2025) continues the same product lines, fire-rating certifications, and manufacturing standards that CDF has relied on for years. Customers familiar with Masonite commercial wood doors will find the same quality and specifications under the Forte Opening Solutions name.
CDF's wood door sourcing is split between two primary vendors based on the fire rating requirement:
- Forte Opening Solutions — fire-rated wood doors (unfinished

This guide answers: What are the acceptable tolerances for commercial door frames?
Why Frame Tolerances Matter
A door is only as good as the frame it hangs in. Out-of-plumb, out-of-level, or racked frames cause doors to bind, drag, swing open or closed on their own, fail to latch, and wear out hardware prematurely. For fire-rated assemblies, frame tolerances directly affect the door-to-frame clearances required by NFPA 80. Getting the frame right is the foundation of a properly functioning door assembly.
Standard Tolerances
The Steel Door Institute (SDI) and the Door and Hardware Institute (DHI) publish the following tolerances for hollow metal frames:
Plumb (Vertical)
Jambs must be plumb within 1/16 inch per 3 feet of height, or 1/8 inch over the full height of the frame, whichever is less. An out-of-plumb jamb causes the door to swing toward or away from the strike side under its own weight.
Level (Horizontal)
The head of the frame must be level
Understanding hurricane-rated door assemblies, wind zone classifications, and Florida Building Code certification requirements.
This guide answers: How Hurricane Ratings Differ Between HVHZ and Standard Wind Zones
Understanding Design Pressure Ratings
Design pressure (DP) is the measure of wind load resistance for door and window assemblies. It is expressed in pounds per square foot (psf) and represents the maximum positive and negative air pressure a product can withstand. Design pressure ratings are established through laboratory testing conducted by accredited testing agencies.
Higher design pressure ratings indicate greater wind load resistance. The required DP rating for a specific project depends on the building location, height, exposure category, and the applicable building code. Architects and engineers specify the required DP rating based on these factors.

Component selection and design pressure requirements for Florida NOA-approved door assemblies
This guide answers: How Hurricane-Rated Assembly Configuration Affects Florida NOA Approval
How Hurricane Assembly Ratings Work
Hurricane-rated door assemblies are tested and approved as complete systems under Florida's Testing Application Standards (TAS). The assembly rating reflects the performance of the entire unit — door, frame, hardware, glazing, and anchorage — tested together under simulated hurricane conditions.
The critical principle is that an assembly's rating equals its lowest-rated component. A door rated for +/- 75 PSF design pressure installed in a frame rated for only +/- 50 PSF results in a +/- 50 PSF assembly. Every component must meet or exceed the required design pressure for the specific opening location.
Design Pressure and Component Selection
Design pressure requirements vary by building location, height above grade, and exposure category. The structural engineer of record

This guide answers: What Happens If You Interpret Door Schedules Without Professional Review
What Is a Door Schedule and Why It Matters
A door schedule is the master reference document on a construction project that defines every door opening in the building. Architects and specifiers create door schedules to communicate the exact configuration of each opening to the general contractor, door supplier, and hardware installer. Misreading a door schedule can result in incorrect door sizes, wrong frame types, mismatched hardware groups, and failed fire inspections — all of which cause delays and added cost.
A typical door schedule is formatted as a table with columns for each opening. While exact column layouts vary by architect, most door schedules include the following fields:

This guide answers: What size kick plate do I need for a commercial door?
Why Door Protection Matters
Commercial doors in high-traffic environments take constant abuse from foot traffic, carts, wheelchairs, gurneys, and cleaning equipment. Without protection, the bottom of the door dents, scratches, and corrodes, leading to premature door replacement. Kick plates, mop plates, and push/pull plates protect the door surface and extend the door's service life significantly.
Types of Door Protection
Kick Plates
Kick plates mount on the push side (or both sides) of the door at the bottom. They protect against foot traffic, shoe scuffs, and impacts from wheeled equipment. Standard kick plate height is 8 to 10 inches. Width should be 2 inches less than the door width (1 inch inset from each edge).
Mop Plates
Mop plates are shorter than kick plates (typically 4 to 6 inches high) and protect the bottom of the door from wet mops, floor scrubbers, and

A fire safety FAQ from CDF Distributors
This guide answers: What labels are required on fire-rated doors and how do you read them?
Why Fire Door Labels Matter
Every fire-rated door, frame, and piece of hardware in a fire-rated assembly must carry a label from an accredited testing laboratory (Underwriters Laboratories, Intertek/WHI, or equivalent). The label is proof that the component was manufactured and tested to the fire resistance standard listed on the label. Without a valid label, the component cannot be used in a fire-rated assembly, and the assembly will fail inspection.
What Information Is on a Fire Door Label
A standard fire door label includes:
- Testing laboratory name and logo (UL, WHI, etc.)
- Fire protection rating (20 min, 45 min, 60 min, 90 min, or 180 min)
- Maximum transmitted temperature rise (if applicable — 250°F, 450°F, or 650°F over 30 minutes)
- Manufacturer name
- Date of manufacture or unique identifier
- Hose stream tested designation (if applicable)
Labels are permanently
How changing hardware components after ordering affects fire ratings, door prep, and project timelines
This guide answers: What Happens If Hardware Substitutions Void Assembly Ratings or Warranties
Why Hardware Substitutions Happen
Hardware substitutions on commercial door projects occur for several reasons, most of which emerge after the original specification has been finalized. Understanding the root causes helps project teams anticipate and prevent substitution requests before they create compliance problems.
- Budget changes — Value engineering rounds may target hardware as a cost reduction opportunity, prompting requests to swap specified locksets, closers, or exit devices for lower-cost alternatives.
- Product availability — Specified hardware may be backordered or discontinued. Lead time pressure can push teams toward whatever is available in the distribution channel.
- Field preferences — Installing contractors may prefer hardware brands or models they are familiar with, requesting changes

This guide answers: Should I use lever handles or door knobs on commercial doors?
The Short Answer: Levers for Almost Every Commercial Application
For most commercial doors, lever handles are the correct specification. ADA and the International Building Code (IBC) require door hardware that can be operated with one hand, without tight grasping, pinching, or twisting of the wrist. Lever handles meet this requirement; round door knobs do not. Door knobs are still permitted on certain non-accessible doors, but levers are the standard for commercial construction.
ADA and Code Requirements
The ADA Standards for Accessible Design (Section 404.2.7) and ICC A117.1 require operable hardware on accessible routes to meet these criteria:
- Operable with one hand without tight grasping, pinching, or twisting
- Operable with no more than 5 pounds of force
- Mounted between 34 and 48 inches above the finished floor
Round door knobs require a twisting motion and
