Mounting double-action hinges, also known as saloon door or swing door hinges, allows doors to open in both directions and automatically return to a closed position. The process involves careful positioning, securing the hinges, and correctly tensioning the springs.
Understanding Double-Action Hinges
Unlike standard butt hinges, double-action hinges have a spring mechanism that allows the door to swing both inward and outward. They typically attach to the surface or edge of the door and the door frame. Correct installation ensures smooth operation and proper door closure.
Tools and Materials Required
Before you begin, gather the necessary tools:
- Double-action hinges (check manufacturer instructions for quantity based on door size and weight)
- Pencil
- Measuring tape or ruler
- Level
- Drill and appropriate drill bits
- Screwdriver (manual or power)
- Hinge tension rod and pin (usually included with hinges)
- Safety glasses
Step-by-Step Installation Guide
Follow these steps to install your double-action hinges:
Step 1: Plan Hinge Placement
- Determine the desired locations for your hinges on both the door and the door frame. Common placements are near the top and bottom edges, and sometimes in the middle for heavier doors.
- Use a measuring tape and pencil to mark the exact positions. Ensure the hinges will align correctly when the door is in the closed position.
- Use a level to ensure your hinge markings are vertically aligned on both the door and the frame.
Step 2: Attach Hinges to the Door
- Place a hinge on the marked position on the edge or surface of the door (depending on hinge type).
- Use the drill to create pilot holes for the screws. Pilot holes prevent wood splitting and make driving screws easier.
- Securely fasten the hinge to the door using the screws provided. Repeat for all hinges on the door.
Step 3: Position and Attach to the Frame
- With the hinges attached to the door, carefully position the door within the door frame. Use shims or blocks underneath the door to support its weight and achieve the desired clearance from the floor.
- Align the hinges on the door with the corresponding marked positions on the door frame.
- Use a level to check that the door is plumb (vertically straight).
- Mark the screw hole locations on the frame through the hinge.
- Drill pilot holes in the frame.
- Securely fasten the hinges to the door frame with screws. Remove shims and test the basic swing of the door.
Step 4: Tensioning the Hinges
Tensioning the hinges is crucial for controlling how the door swings and returns. This step utilizes the spring mechanism.
- Locate Tension Holes: Find the tension holes or slots on the barrel of the hinge. The reference notes positioning on the left door with the tension holes up.
- Insert Tension Rod: Insert the tension rod into the lug or one of the tension holes on the hinge barrel.
- Apply Tension: Turn towards the left to add tension. As you turn, the spring inside the hinge tightens. Each click or position represents an increment of tension.
- Insert Tension Pin: Once the desired tension is reached, insert the tension pin into the nearest exposed tension hole on the hinge barrel to hold the tension in place. Remove the tension rod.
- Repeat for All Hinges: Repeat the tensioning process for each hinge.
- Testing and Adjustment: Test the door's swing. If it swings back too slowly or quickly, or doesn't close properly, adjust the tension on the hinges. The reference provides a starting point: we recommend starting with two holes of tension on the top hinge. You may need more or less tension depending on the weight and size of the door. Ensure all hinges have the same amount of tension for balanced movement.
Tips for Success
- Always read the specific instructions included with your hinges, as designs can vary.
- For heavy doors, use three or more hinges for better support.
- Ensure pilot holes are the correct size – not too small (can cause splitting) and not too large (screws won't hold).
- Test the door swing frequently during installation to catch alignment issues early.
- Tensioning may require some trial and error to get the swing just right.
By following these steps, including the critical tensioning process, you can successfully mount double-action hinges for smooth, reliable door operation.
