What is a Knock Down Door Frame?
A knock down door frame is a type of frame that is shipped in disassembled parts, typically consisting of three main components: the strike jamb, hinge jamb, and head. The design allows for easy transportation, reduced shipping costs, and straightforward installation. KD frames are primarily made from cold-rolled steel to ensure durability and strength, making them suitable for various applications.
Benefits of Knock Down Door Frames
Knock down door frames offer several advantages over traditional welded frames. Firstly, their modular design allows for easy adjustment during installation, accommodating different wall thicknesses. This flexibility is crucial in commercial and institutional settings where wall structures may vary. Additionally, KD frames are often lighter and easier to handle, reducing labor costs during installation.
Cost-Effectiveness
One of the standout benefits of KD frames is their cost-effectiveness. They are typically more affordable than welded frames, making them an attractive option for large-scale projects. The ability to flat-pack these frames for shipping further reduces transportation costs, which can be significant in budget-sensitive projects.
Versatility in Applications
KD frames are highly versatile and can be used in various settings, including:
- Commercial Buildings: Ideal for office spaces, retail stores, and public facilities.
- Institutional Buildings: Suitable for schools, hospitals, and government structures.
- Residential Applications: Increasingly used in home renovations, especially where drywall is involved.
Types of Knock Down Door Frames
Understanding the different types of KD door frames can help in selecting the right one for your specific needs.
KD Drywall Frame
The KD drywall frame is designed for interior applications. It wraps around the wall after the drywall is installed, making it perfect for both steel and wood doors. It offers a clean finish and is particularly useful in commercial and institutional buildings.
KD Masonry Frame
This type of frame can be used for both interior and exterior applications. It is designed to accommodate masonry walls and can be installed before or after the wall construction. KD masonry frames are robust and suitable for heavy-duty applications, adhering to industry standards.
KD Hollow Metal Frame
Hollow metal frames are trending in the steel door industry due to their ease of installation. They consist of three components that lock together, providing a sturdy frame that can fit various door sizes and configurations. These frames are especially beneficial in environments requiring quick installations.
KD Frames with Drywall Returns
These frames come with drywall returns, making them ideal for drywall construction with steel or wood studs. They offer a seamless look and are customizable to fit specific rough opening sizes.
Installation Process for KD Door Frames
Installing a knock down door frame is a straightforward process. Here are the basic steps involved:
- Prepare the Opening: Ensure that the rough opening is correctly measured and free from obstructions.
- Assemble the Frame: Join the three components (strike jamb, hinge jamb, and head) using the provided hardware.
- Position the Frame: Place the assembled frame into the rough opening, ensuring it is level and plumb.
- Secure the Frame: Use anchors or screws to secure the frame in place, ensuring it can support the weight of the door.
- Install the Door: Hang the door according to the manufacturer’s instructions, adjusting as necessary for a proper fit.
Maintenance of Knock Down Door Frames
Maintaining KD frames is essential for ensuring their longevity and performance. Regular inspections should be conducted to check for signs of wear, particularly at the hinges and anchors. Any rust or corrosion should be addressed promptly to prevent deterioration. Additionally, keeping the door and frame clean will enhance their appearance and functionality.
