A non-handed door closer is a versatile door hardware device that can be installed and function correctly on doors that open to either the left or the right, eliminating the need to specify or stock separate models for each door swing direction. Its design allows it to be oriented or adjusted during installation to suit the specific handing of any door.
Understanding Non-Handed Door Closers
The primary advantage of a non-handed door closer lies in its universal adaptability. Unlike handed closers, which are manufactured specifically for either left-hand (LH) or right-hand (RH) doors, a non-handed closer is designed or assembled to rotate into the correct position for use on both left and right-hand doors. This flexibility simplifies the selection, ordering, and installation processes considerably.
For a deeper understanding of door handing, you can refer to resources like ASSA ABLOY's guide on door handing.
How They Work
Non-handed door closers achieve their versatility through several design characteristics:
- Symmetrical Design: Many models feature a symmetrical body that allows the main arm to be attached and function correctly regardless of the closer's orientation on the door or frame.
- Adjustable Components: Some non-handed closers may include components that can be easily repositioned or rotated during installation to accommodate the door's swing direction.
- Universal Mounting: The mounting hole patterns and closer body itself are engineered to facilitate installation on either side of the door (push or pull side) for both left and right-hand opening doors.
Key Benefits of Non-Handed Door Closers
The flexibility offered by non-handed door closers translates into several practical advantages for various stakeholders:
- Simplified Inventory Management:
- Distributors and Suppliers: No need to stock separate left-hand and right-hand models, reducing inventory complexity and storage space.
- Contractors and Installers: Fewer specific parts to carry on job sites, minimizing the risk of having the wrong closer on hand.
- Reduced Ordering Errors:
- Eliminates the common mistake of ordering the incorrect door handing, saving time and avoiding return shipments.
- Ease of Installation:
- Installers don't need to spend time determining door handing before mounting the closer, streamlining the process.
- Greater flexibility in field adjustments.
- Cost Efficiency:
- Potentially lower overall costs due to reduced inventory holding and fewer errors.
- Versatility in Applications:
- Ideal for projects where door handing might not be fully determined until installation or for facilities with a mix of door types.
Handed vs. Non-Handed Door Closers: A Comparison
Understanding the differences between these two types of closers is crucial for proper selection.
| Feature | Handed Door Closer | Non-Handed Door Closer |
|---|---|---|
| Installation | Specific to Left-Hand (LH) or Right-Hand (RH) doors | Universal; works on both LH and RH doors |
| Inventory | Requires separate SKUs for each handing | Single SKU suitable for all standard applications |
| Flexibility | Limited to specified door swing | High; adaptable to any standard door swing |
| Ordering | Must specify handing precisely | Ordering errors related to handing are eliminated |
| Field Adjustment | Typically fixed for its handed orientation | Often designed for rotational adjustment during install |
| Common Use | Older installations, highly specialized applications | Modern construction, general-purpose installations |
Choosing the Right Non-Handed Closer
While non-handed closers offer great flexibility, it's still essential to select the correct model based on other critical factors:
- Door Weight and Size: Ensure the closer's spring power is appropriate for the door's dimensions and weight to provide proper closing force.
- Application Environment: Consider if the closer will be used indoors or outdoors, in a high-traffic area, or on a fire-rated door.
- Mounting Type: Determine if you need a surface-mounted, concealed overhead, or floor spring closer. Common surface-mounted arm configurations (e.g., regular arm, parallel arm, top jamb) are often compatible with non-handed closer bodies.
- Features: Look for additional features like adjustable backcheck, delayed action, or hold-open functionality if required.
- Compliance: Verify that the closer meets relevant building codes, accessibility standards (like ADA), and fire safety regulations. For more information on ADA compliance for doors, refer to resources like the U.S. Access Board.
By opting for non-handed door closers, you embrace a solution that simplifies hardware management, reduces installation complexities, and ensures compatibility across a wide range of door applications.
