Installation Exterior Sliding Door for Garage
Installing an exterior sliding door requires precision and attention to detail. Here are the essential steps on how to install it:
Step-by-Step How to Install an Exterior Automatic Sliding Door
Step 1: Open a Trench, over which the Sliding Door guide will go
The first step is to create a trench in the ground to install the sliding door guide. Be sure to measure and mark the proper location, following the dimensions of the guide system supplied with the door.
Carefully dig the trench, making sure it’s level and aligned correctly. The trench should follow the path of the sliding garage door and will be used to place the running axles.
Step 2: Make the concrete base to place the Rolling Axles
To ensure the stability and proper functioning of the sliding door, it is necessary to build a concrete base where the running axles will be placed. In the installation of the automatic sliding door it is very important to have the correct size and thickness for the door we have chosen.
Prepare the ground, lay the formwork and pour the concrete into the base. Be sure to level and smooth the surface for a solid base.
Step 3: Installing the Running Rails
Once the concrete base is dry and firm, proceed to install the running rails on the guide that you have previously placed in the trench. Be sure to follow the manufacturer’s instructions and attach the rails securely to the concrete base.
Step 4: Install the Motor on Another Concrete Base
To know how to install a sliding door motor, the first thing to do is to create another concrete base to install the automatic sliding door motor.
Follow the base construction process similar to the previous step, and be sure to take into account the dimensions and engine requirements specified by the manufacturer.
It is important to consider that the sliding garage door motor will require an electrical connection. Therefore, it will be necessary to build a concrete base for the motor that includes an electrical output. It is recommended to leave at least 40 cm of wiring length to ensure a convenient connection. In addition, this electrical outlet will also be used to connect other garage door accessories.
Step 5: Insert the Motor into the Base
Once the concrete base is ready, place the motor on it, making sure to follow the instructions given by the manufacturer. Secure the motor to the base securely and verify that it is level for optimal operation. Connect the motor to the electrical outlet built next to the base.

Step 6: Place the Door on the Rail
With the motor and running rails in place, it’s time to place the door leaf on the rail. Gently slide the door onto the track track, making sure it’s properly aligned and properly engaged.
It is necessary to install the additional fasteners included in the door itself to prevent it from falling.
Step 7: Prepare the engine and make the necessary adjustments
Unlock the door motor and make the necessary adjustments to ensure that the sliding door slides smoothly and without obstructions. Verify that the safety sensors are correctly installed and working properly.
Step 8: Check if everything is working properly
Before completing the installation, carry out extensive tests to ensure the correct operation of the external automatic sliding door. Make sure that the opening and closing are smooth and that all components are in good condition.
Step 9: Connect the motor to the base
Once you are satisfied with the operation of the door, secure the motor to the concrete base using the anchoring devices provided. Make sure it is firmly attached to prevent any unwanted movement.
Step 10: Set up your computer’s electrical system
Set up the door’s electronic systems, such as remote controls and security systems. Follow the manufacturer’s instructions to make sure everything is properly set up and operating smoothly.
Step 11: Finish by attaching the protective elements
Finally, install additional protective elements, such as safety sensors and obstacle detection systems.
These components are crucial to ensure the safety and proper functioning of the automatic sliding door. Place the protective cover or hood on the motor and we are done.
