Door Handing Explained: A Comprehensive Guide

Understanding door handing is a crucial step in successfully installing door hardware. Many homeowners are baffled by the seemingly simple task of choosing the right door handle, only to find themselves staring at mismatched hardware and an awkwardly installed door. This article will demystify door handing, explaining what it is, how to determine it, and why getting it right is so important.

What is Door Handing?

Door handing refers to the direction a door's lever or handle points when viewed from the outside. It's not about your personal handedness (left-handed or right-handed) – it's solely determined by the position of the hinges relative to the door's swing. This is a key distinction; door handing isn't about which hand you use to open the door, but rather the physical orientation of the door's hardware in relation to its hinges and the direction it opens.

This seemingly small detail is critical because incorrectly handed hardware will either be impossible to install or will interfere with the door frame, leading to frustration and potentially damage. Understanding door handing is essential for a smooth installation process, ensuring your new handles and levers function correctly and look aesthetically pleasing.

Types of Door Levers and Handing

Not all door levers require you to specify handing. Many modern door levers are designed to be "universal" or "reversible." These straight levers can be installed on either a left-handed or right-handed door because their internal mechanisms allow for easy adjustment.

However, some levers, particularly those with a curved design or non-turning handles found in certain handle sets, do require specific handing. Manufacturers will typically denote this with "LH" for left-hand and "RH" for right-hand in their product descriptions and model numbers (e.g., Schlage LH, Kwikset RH).

Determining the Correct Handing

Determining the correct handing is a straightforward process:

1. Identify the Outside: Stand on the exterior side of the door. This is the side from which you approach the door to enter. For an interior door, this would be the hallway side.

2. Locate the Hinges: Observe the hinges. Are they on the left or the right side of the door?

3. Determine the Handing:

   • Hinges on the Left: You need a left-hand (LH) lever.
   • Hinges on the Right: You need a right-hand (RH) lever.

The correctly installed lever will point in the same direction as the hinges when viewed from the outside. A simple test is to visualize the lever's position; if it strikes the door frame when opened, you have the wrong handing.

Double Doors and Handing

Double doors (like French doors) add a layer of complexity. These doors require both left-hand and right-hand levers. One door, typically the active leaf (the door with the locking mechanism), will require a specific handed lever while the inactive leaf typically uses a complementary lever.

For example, if the active leaf has its hinges on the left and swings inward, it needs a left-hand lever. The inactive leaf, with its hinges on the right, will need a right-hand lever. Ordering the wrong handing for a double door will result in installation difficulties and potential damage to the door frames.

Key Considerations for Double Doors:

• Active vs. Inactive Leaf: Identify which door is the active (locking) leaf. The active leaf's handing dictates the handing of the entire door system.

• Swing Direction: Note whether the doors are inswing or outswing. This affects the handedness calculation, especially for outswing doors.

• Accurate Ordering: Always order both the LH and RH levers specifically designed for double doors to ensure a proper fit and function.

Common Mistakes to Avoid

Several common mistakes can be avoided with a little attention to detail:

• Confusing Personal Handedness with Door Handing: Your preference for using your left or right hand has no bearing on door handing.

• Ignoring Hinge Placement: Always start by checking hinge placement from the outside of the door.

• Failure to Specify Handing: When purchasing online or from a supplier, always clearly specify the door handing (LH or RH) to avoid receiving incorrect hardware.

• Assuming Reversibility: Not all door levers are reversible. Double-check before assuming your chosen lever can be used on any door.

Summary: Mastering Door Handing

Successfully navigating the world of door handing simply requires careful observation and understanding these key principles. By correctly identifying the outside of the door, noting the hinge location, and understanding the distinction between single and double doors, you can confidently choose the right door hardware, ensuring a smooth and successful installation. Remember, the term 'door handing' is all about the orientation of the door's hardware relative to the hinges, and nothing else. So, take your time, carefully check, and enjoy the process of correctly installing your new door hardware.

Frequently Asked Questions: Understanding Door Handing

What is door handing?

Door handing refers to the direction a door's lever or handle points when viewed from the outside. It's determined by the hinge location relative to the door's swing, not the user's dominant hand. This is crucial for correct door hardware installation.

How do I determine if my door is left-hand (LH) or right-hand (RH)?

Stand outside the door. Look at the hinges. If the hinges are on the left side of the door, it's a left-hand door. If they're on the right, it's a right-hand door. This method works regardless of whether the door swings inward or outward. An alternative method is to open the door, stand with your back to the hinges, and note which hand is closest to the doorknob; that hand corresponds to the door's handing.

Do all door levers require specifying handing?

No. Straight or universal levers can be installed on either left-hand or right-hand doors. Many interior passage, privacy, and keyed levers also have reversible mechanisms, eliminating the need to specify handing. However, curved or non-turning levers often require selecting the correct LH or RH version. Manufacturers usually indicate this in their product model numbers (e.g., using "LH" or "RH").

What about double doors (French doors)?

Double doors require both a left-hand and a right-hand lever. One door will have a left-hand lever and the other a right-hand lever, depending on which leaf (door) has the locking mechanism and the hinge location. Make sure to purchase both LH and RH versions to avoid installation problems.

What if I install the wrong handing?

Incorrect handing will result in the lever striking the door frame, preventing proper operation. You'll likely need to remove and reinstall the hardware with the correctly handed lever.

What is the difference between inswing and outswing doors?

An inswing door opens into the room, while an outswing door opens away from the room. While hinge location determines handing, the swing direction is a separate specification and necessary for complete ordering information.

How do I determine the correct handing for an outswing door?

For outswing doors, the handing is reversed from inswing doors. If the hinges are on the left, it's a right-hand door; if they are on the right, it's a left-hand door.

What if I'm unsure about the handing of my door?

Carefully examine the hinge placement from the outside of the door. If you're still unsure, take a photo of the hinges and the door's swing direction and consult a hardware professional or the manufacturer's instructions for your specific door hardware.
