Rixson floor closers are essential hardware for controlling door movement in commercial and residential buildings. Proper adjustment ensures smooth operation, safety, and enhanced durability. This article provides an in-depth guide on how to adjust Rixson floor closers effectively, including tips on speed, latching, and backcheck settings. Whether for maintenance or installation, understanding these adjustments can improve door functionality and longevity.
| Adjustment Type | Purpose | Tools Needed | Typical Procedure |
|---|---|---|---|
| Closing Speed | Controls how fast the door closes after opening | Flathead screwdriver, Allen wrench | Turn the adjustment screw clockwise to slow and counterclockwise to speed up |
| Latching Speed | Controls speed during last few inches of closing | Flathead screwdriver | Adjust the latching speed screw to ensure door latches securely |
| Backcheck | Prevents door from opening too quickly or too far | Allen wrench, screwdriver | Adjust to increase or decrease resistance at the door’s opening |
What Is a Rixson Floor Closer and Why Proper Adjustment Matters
A Rixson floor closer is a mechanical device installed at the floor level to control the closing of heavy doors. Unlike overhead door closers, floor closers are concealed within the floor, offering a sleek design and durability. Proper adjustment is critical because it maintains door safety, prevents slamming, and extends the lifespan of the hardware.
In commercial environments, correctly adjusted floor closers enhance security and accessibility by ensuring doors close reliably and quietly. Improper adjustment can lead to damage, increased repair costs, and safety risks such as doors closing too quickly or failing to latch properly.
Tools and Safety Precautions for Adjusting Rixson Floor Closers
Before beginning any adjustments, gather the necessary tools: a flathead screwdriver, Allen wrench set, and potentially a lubricant recommended by Rixson. Wear safety gloves and ensure the door is supported or held open to prevent accidental injury.
Checking the manufacturer’s manual for specific Rixson floor closer models is advised because adjustment points may vary. If the unit is newly installed, a preliminary inspection to confirm proper installation is beneficial prior to adjustment.
Step-By-Step Guide to Adjusting Closing Speed
The closing speed controls the main timing of the door from fully open to near closure. To adjust:
- Locate the closing speed adjustment screw, typically found inside the closer’s access plate.
- Using a flathead screwdriver, turn the screw clockwise to slow the door closing speed and counterclockwise to increase speed.
- Test the door after small adjustments to ensure it closes smoothly without slamming.
- Repeat until the desired speed is achieved, considering door weight and building traffic flow.
Adjusting Latching Speed for a Secure Close
Latching speed adjustment ensures the door pulls firmly into the frame in the last few inches of movement. This adjustment is crucial for securing the door and reducing noise.
- Identify the latching speed adjustment screw located near the closing speed screw.
- Turn the screw gradually to set the door’s slow close in the final range.
- Too fast latching can cause damage to the door frame or lock mechanism, while too slow may fail to engage the latch properly.
- Test repeatedly to find the balance between speed and secure closure.
Backcheck Adjustment to Prevent Door Damage
The backcheck function prevents the door from opening too quickly or violently, which can damage the door, walls, or adjoining hardware.
- Locate the backcheck adjustment on the closer body, often a separate valve or screw.
- Turn to increase resistance if the door opens too fast or forcefully.
- Adjust gradually to avoid making the door too hard to open.
- Confirm the adjustment by opening the door to the stop point and noting the resistance.
Common Issues and Troubleshooting Tips
Problems with Rixson floor closers often relate to incorrect adjustments or accumulated debris inside the mechanism. Common issues include:
- Door slamming: Usually caused by closing speed set too fast or lack of lubrication.
- Door not latching: Often a result of latching speed set too slow or misaligned door frame.
- Door difficult to open: Backcheck setting may be too high or mechanical obstruction present.
- Noisy operation: Can be resolved by cleaning and lubricating moving parts during maintenance.
Regular inspection and servicing according to Rixson’s guidelines keep the floor closer functioning optimally.
Maintenance Tips to Maximize Floor Closer Lifespan
To ensure Rixson floor closers function smoothly for years, consistent maintenance is essential:
- Regular Cleaning: Remove debris or dirt from around the closer and inside the access plates.
- Lubrication: Apply manufacturer-recommended lubricant to pivot points and internal components.
- Periodic Adjustment Check: Doors and hardware settle over time, requiring readjustment of speed and backcheck.
- Inspect for Wear and Damage: Replace worn parts promptly to prevent further damage.
When to Call a Professional for Rixson Floor Closer Adjustment
While many adjustments can be made by experienced maintenance personnel, professional locksmiths or door technicians are recommended for:
- Complex installations involving heavy or oversized doors
- Persistent operational issues after multiple adjustments
- Severe mechanical damage or component replacements
- Ensuring compliance with building codes and ADA accessibility requirements
Calling a professional not only ensures proper adjustment but also extends the life and safety of the door system.
