How To Install Commercial Door Hardware？

Properly installed commercial door hardware is essential for the security, functionality, and safety of any business premises. Unlike residential hardware, commercial-grade products are built to withstand high traffic and heavy use while complying with strict building codes. Getting the installation right the first time prevents costly repairs, ensures accessibility, and protects your assets.

This guide provides a comprehensive overview of how to install commercial door hardware correctly. We will walk you through the necessary preparations, the step-by-step installation process for common components like locks and closers, and the final checks needed to guarantee a perfect setup. Following these instructions will help you achieve a secure and professional installation that lasts.

Gearing Up for Installation

Before you begin, gathering the right tools and materials is crucial for a smooth and efficient process. A well-prepared workspace minimizes delays and helps you avoid common installation mistakes.

Essential Tools and Materials

Having the correct tools on hand is non-negotiable. While the specific tools may vary slightly depending on the type of hardware, a standard kit should include:

· Drill with various bit sizes: For creating pilot holes and securing screws.

· Screwdriver set: Both Phillips and flat-head screwdrivers are necessary.

· Tape measure: For precise measurements of the door and frame.

· Level: To ensure all components are perfectly aligned.

· Chisel and hammer: For mortising, if you are installing hardware that needs to be recessed into the door.

· Safety glasses: To protect your eyes from dust and debris.

· Pencil or marker: For marking drilling and cutting points.

· Manufacturer's template: Most commercial door hardware comes with a paper template to guide drilling. Do not lose this!

Preparing the Door and Frame

Once your tools are ready, the next step is to prepare the door and frame. A clean and accurately marked surface is the foundation of a successful installation.

1.Inspect the Door: Check the door for any damage, such as warping or cracks, that could interfere with the hardware's function. Ensure the door is properly hung and swings freely without catching on the frame.

2.Use the Template: Carefully position the manufacturer-provided template on the door. Secure it with tape. The template will show you exactly where to drill holes for the lockset, latch, and other components.

3.Mark Drilling Points: Use a pencil or an awl to mark the center of each hole indicated on the template. Double-check your marks for accuracy before proceeding. An incorrect measurement at this stage can lead to misaligned hardware.

4.Prepare the Frame: Mark the location for the strike plate on the door frame. This should align perfectly with the latch bolt when the door is closed.

How to Install a Commercial Lockset

The lockset is the heart of your door's security. Commercial locksets, such as cylindrical or mortise locks, are more robust than their residential counterparts. The installation process requires precision.

Step 1: Drill the Holes

Using the marks you made from the template, begin drilling the necessary holes.

· Face Hole: Drill the main hole through the face of the door for the lock body. Start from one side and drill about halfway through, then complete the hole from the other side. This technique prevents the wood from splintering.

· Latch Hole: Drill the hole into the edge of the door for the latch assembly. Make sure this hole is straight and deep enough to accommodate the entire latch mechanism.

Step 2: Install the Latch

With the holes drilled, you can now install the latch.

1.Slide the latch bolt assembly into the hole on the door's edge.

2.Place the latch plate over the assembly and trace its outline with a pencil.

3.If required, use a chisel to create a shallow mortise so the latch plate sits flush with the door edge.

4.Secure the latch plate with the provided screws.

Step 3: Install the Lock Cylinders

Now, install the main lock components.

1.Insert the exterior lock cylinder (the side with the keyhole) through the large face hole, ensuring its tailpiece passes through the latch mechanism correctly.

2.Attach the interior cylinder or thumb-turn assembly on the other side of the door.

3.Secure both sides together using the mounting screws. Tighten them evenly, but avoid over-tightening, which can cause the lock to bind.

Step 4: Install the Strike Plate

The final piece of the lockset is the strike plate, which goes on the door frame.

1.Close the door to mark where the latch bolt touches the frame.

2.Align the strike plate with this mark and trace its outline.

3.Chisel a mortise for the strike plate so it sits flush with the frame.

4.Drill a hole for the latch bolt to enter.

5.Fasten the strike plate to the frame with screws.

How to Install a Commercial Door Closer

A door closer is a critical piece of commercial door hardware, especially for fire-rated doors and high-traffic entrances. It ensures the door closes automatically, enhancing security and energy efficiency.

Step 1: Choose the Mounting Position

Door closers can typically be installed in one of three ways: standard arm, top jamb, or parallel arm. The parallel arm installation is the most common for commercial applications as it reduces the risk of vandalism. Refer to the manufacturer's instructions and template to determine the best position for your door.

Step 2: Mount the Closer Body

1.Using the provided template, mark the drilling locations for the closer body on the door (for standard or parallel arm installations) or on the frame (for top jamb installations).

2.Drill pilot holes for the mounting screws.

3.Attach the closer body to the door or frame, making sure it is level.

Step 3: Install the Closer Arm

1.The closer arm consists of two parts: the main arm and the forearm. Attach the main arm to the spindle on top of the closer body according to the instructions.

2.Mount the forearm shoe to the door frame (for standard arm) or the door (for parallel arm).

3.Connect the main arm and forearm.

Step 4: Adjust the Closer

After installation, you must adjust the closer's settings for proper operation.

· Closing Speed: Controls how fast the door closes from the fully open position.

· Latching Speed: Controls the speed of the final few inches of closing, ensuring the door latches securely.

· Backcheck: Cushions the opening swing to prevent the door from being slammed against a wall.

Turn the adjustment screws in small increments to fine-tune these settings until the door closes smoothly and latches firmly without slamming.
