Tools and Materials You'll Need
Okay, let's get down to business. First off, you'll need to gather the right tools and materials. Here's a quick list:
- Tools: A drill, a saw (either a hand saw or a power saw depending on what you're comfortable with), a measuring tape, a level, a screwdriver set, and a chisel.
- Materials: The rotary floor spring kit (duh!), some screws, bolts, and nuts, and a bit of wood filler if you need to patch up any holes later on.
Step 1: Measure and Mark
The very first step is to measure the door and the floor. You want to make sure the rotary floor spring will fit in the right spot. Use your measuring tape to find the center of the door. Then, mark this point on the floor directly below. This is where the main part of the rotary floor spring will go.
Next, check the dimensions of the threshold. You need to figure out how much space you have to work with. If the threshold is too thick or too thin, you might need to adjust your installation plan.
Step 2: Prepare the Threshold and Floor
Now it's time to prepare the area. If there are any bumps or uneven spots on the threshold or the floor, use a chisel or sandpaper to smooth them out. You want a nice, flat surface for the rotary floor spring.
If your rotary floor spring comes with a mounting plate, you'll need to cut a recess in the floor for it. Use your saw to carefully cut out a space that's the same size as the mounting plate. Make sure it's deep enough so that the plate sits flush with the floor.
Step 3: Install the Mounting Plate
Once the recess is ready, it's time to install the mounting plate. Place it in the recess and use your level to make sure it's perfectly horizontal. Then, use your drill to make holes in the floor through the holes in the mounting plate. Insert the screws and tighten them securely.
Double - check that the mounting plate is still level. If it's off - kilter, it can cause problems with the door's operation later on.
Step 4: Attach the Spring Unit
Now, take the main spring unit of the rotary floor spring. There are usually some bolts or screws that you'll use to attach it to the mounting plate. Line up the holes in the spring unit with the holes in the mounting plate and insert the bolts or screws. Tighten them down, but don't go overboard. You want it secure, but you don't want to strip the threads.
Step 5: Install the Pivot Hinge
The Rotary Floor Spring Pivot Hinge is a crucial part of the setup. You'll need to attach it to the bottom of the door. First, mark the position of the pivot hinge on the door. Then, use your drill to make holes and insert the screws to attach it.


Make sure the pivot hinge lines up perfectly with the spring unit on the floor. If it's off even a little bit, the door might not swing properly.
Step 6: Connect the Door and the Spring
Once the pivot hinge is on the door, it's time to connect the door to the spring. Lower the door onto the spring unit. The pivot hinge should fit snugly into the corresponding part of the spring.
You might need to make some small adjustments to get the door to sit just right. Use your level to check that the door is vertical. If it's not, you can loosen the screws on the pivot hinge or the spring unit and make the necessary tweaks.
Step 7: Test and Adjust
Now that everything is connected, it's time to test the door. Open and close the door a few times to see how it works. If the door doesn't close smoothly or if it's too hard to open, you'll need to make some adjustments.
Most rotary floor springs have adjustment screws that you can turn to change the closing speed, the latching force, and the backcheck function. Play around with these screws until you get the door operating the way you want it to.
Step 8: Finishing Touches
Once you're happy with how the door is working, it's time for the finishing touches. Use some wood filler to patch up any holes or gaps around the mounting plate or the pivot hinge. Sand it down so it's smooth, and then you can paint or stain it to match the floor or the door.
