How to Install Offset Pivot Hinges on Your Commercial Glass Storefront Door

An offset pivot hinge is a type of hinge commonly used on commercial glass storefront doors. It is called an offset pivot hinge because it is mounted off-center from the edge of the door and jamb, creating a sleek and modern look while also providing a secure and stable installation. Offset pivot hinges are preferred for storefront doors because they allow for a larger and heavier door to be installed, provide smoother operation, and are more secure than traditional hinges. Additionally, they allow for a more flush appearance when the door is closed, giving the storefront a clean and modern look. Installing offset pivot hinges can be a bit challenging, but by following these step-by-step instructions, you can ensure that your storefront door is properly installed and will operate smoothly for years to come.

Installing the Bottom Pivot

To prepare the jamb for the bottom pivot, start by installing the frame portion of the bottom pivot into the frame using the screws provided. Next, install the door jamb into the opening and anchor the pivot to the floor through the center hole of the pivot. This is an important step as it prevents the frame from twisting and causing damage to the pivot. Once the pivot is securely anchored to the floor, attach the threshold to the pivot using the screws that are provided. This will ensure that the threshold is properly aligned and will function as intended.

Installing the Top Pivot

To prepare the transom bar for the top pivot, begin by installing the frame portion of the pivot using the screws provided. This step is important for ensuring that the door operates smoothly and that the pivot is securely anchored in place. By following these instructions and properly preparing the transom bar for the top pivot, you can be confident that your storefront door will provide reliable service for years to come.

Installing the Intermediate Pivot Hinges

To prepare the jamb for the intermediate pivot, begin by installing the frame portion of the pivot using the screws provided. It's important to note that intermediate pivots are required for doors that are 8 feet or taller. This is because taller doors require additional support to ensure proper alignment and smooth operation. By following these instructions and installing the intermediate pivot as required, you can be confident that your door will function properly and provide years of reliable service.

Attaching the Door to the Frame

Follow these steps to attach the door to the frame:

1. In cases where intermediate pivots are required, it's important to retract the intermediate pivot pin to allow the door pivot to clear. To do this, start by removing the bottom hole plug and retracting the pivot pin. Once the door is in place, raise the pivot pin to engage the door pivot and adjust it to a "just snug" position before reinstalling the bottom hole plug. To set the door, begin by retracting the frame intermediate pivot pin to allow the door pivot to clear. Next, set the door onto the bottom pivot and push the top pivot pin into the retracted position. Then, locate the top door pivot under the frame and release the pin. By following these steps carefully, you can ensure that the door is properly installed and will operate smoothly for years to come.
2. Place the door onto the lower pivot and retract the top pivot pin. Find the top door pivot below the frame and release the pin.
3. Modify the door clearance by rotating the pivot pin in a clockwise direction to lower the door and counterclockwise to elevate the door. Once the final adjustment is done, use a hex key wrench to securely tighten the set screw. The clearance between the top rail of the door and the frame should be 1/8".
4. Check that the door opens and closes smoothly.

Conclusion

In conclusion, installing offset pivot hinges on a commercial glass storefront door can be a bit challenging, but by following the step-by-step instructions provided above, you can ensure a secure and stable installation that will function smoothly for years to come. Properly preparing the jamb, installing the bottom pivot, top pivot, and intermediate pivot hinges, and attaching the door to the frame are all essential steps to ensure a successful installation.
