When it comes to selecting hardware handles for doors or cabinets, the installation method is a crucial consideration that can impact both the aesthetics and functionality of your hardware. Two common installation methods for handles are “Bolt Through” and “Back to Back.” Understanding these two methods can help you make the best choice for your needs. Let’s explore their differences and the specific advantages each offers.
1. Bolt Through Fixing
Definition: The “Bolt Through” fixing method involves drilling a hole through the door or cabinet and using a bolt to secure the handle in place. The bolt passes through the handle on one side of the door, through the drilled hole, and is then fastened with a nut or decorative cap on the other side.

Advantages:
- Strong and Secure: This method provides a very secure installation, making it ideal for heavy-duty or frequently used doors, such as entry doors or bathroom doors.
- Versatile Use: “Bolt Through” fixings can be used on a variety of door materials, including wood, metal, and even glass with the proper hardware.
- Durability: Because the handle is directly attached to the door via bolts, it can withstand substantial force, reducing the risk of the handle becoming loose over time.
Best for:
- Heavy doors
- High-traffic areas
- Doors requiring a robust attachment
2. Back to Back Fixing
Definition: The “Back to Back” fixing method involves mounting two handles on either side of the door. These handles are attached to each other through the door using a single set of bolts or a connecting rod, essentially securing them back to back.

Advantages:
- Clean and Symmetrical Appearance: The “Back to Back” fixing provides a neat, symmetrical look, with no visible screws or bolts from the outside, which can enhance the overall aesthetic of the door.
- Ideal for Glass Doors: This method is particularly suited for glass doors or double-sided doors, as it does not require extra holes for fixing and provides a secure attachment without compromising the integrity of the door material.
- No Additional Hardware Needed: Because the handles are fixed to each other, there is no need for additional fasteners like nuts or caps, simplifying the installation process.
Best for:
- Glass doors
- Double-sided doors (e.g., commercial entryways)
- Applications where aesthetics are a priority
Key Differences:
| Feature | Bolt Through | Back to Back |
|---|---|---|
| Installation Method | Bolted through the door | Attached back to back through the door |
| Suitable for | Wood, metal, heavy-duty doors | Glass, double-sided doors |
| Appearance | Visible screws or caps on one side | Clean, symmetrical appearance |
| Ideal for | High-traffic or heavy doors | Glass doors, aesthetic-focused installations |
| Installation Complexity | Requires additional hardware (nuts/caps) | No extra hardware needed |
Which One Should You Choose?
Choosing between “Bolt Through” and “Back to Back” depends on the specific needs of your project. If you require a strong and secure fixing for a heavy or frequently used door, the “Bolt Through” method is the way to go. However, if aesthetics and a clean look are priorities, especially for glass or double-sided doors, the “Back to Back” method offers a more polished appearance.
Both installation methods have their unique benefits, and selecting the right one will ensure that your hardware not only looks good but also performs well for years to come. Whether you are working on a residential or commercial project, understanding these differences will help you make an informed decision that meets both your functional and aesthetic needs.
