Description
FAAC Beam Fork Support Adjustable – B614/B680H – 428806
The FAAC Adjustable Beam Fork Support is a genuine barrier accessory designed to support the free end of a compatible FAAC barrier boom when the barrier is in the closed position.
Installed at the end of the vehicle passage, the barrier boom lowers into the fork as it closes, providing a stable resting point for the end of the beam.
FAAC Part Number: 428806
🚧 Fixed Support for the Barrier Beam
The 428806 provides additional support for longer barrier boom installations.
When the barrier closes, the end of the boom rests within the fork, helping support and stabilise the beam in its horizontal position.
This makes it particularly useful for:
- Longer barrier boom arms
- Commercial entrances
- Car parks
- Industrial sites
- Apartment complexes
- High-traffic vehicle access points
FAAC lists the adjustable fork as a common B614 barrier accessory and includes it in its B680H installation accessories.
🔧 Ground-Mounted Design
Unlike the FAAC 428805 Adjustable End Foot, which is attached directly to the moving boom, the 428806 fork remains stationary.
The beam lowers into the support when closed and lifts clear when the barrier opens.
This means there is no additional moving support attached to the boom itself.
📐 Adjustable Support
The support fork is adjustable to allow the resting position to be aligned with the installed height of the barrier boom.
Correct adjustment ensures the boom is properly supported when closed without interfering with normal opening and closing movement.
🧱 Support Plate
FAAC also offers the dedicated:
- 737621 – Support Plate for Fork
The support plate is used for installation of the fork support and is listed by FAAC alongside the 428806 for both B614 and B680H applications.
⚙️ Fork Support vs End Foot
FAAC offers two different methods of supporting the end of a barrier boom:
428806 – Adjustable Fork Support
- Fixed in position at the end of the passage
- Beam lowers into the fork when closed
- Does not travel with the boom
- Uses support plate 737621
428805 – Adjustable End Foot
- Mounted directly to the barrier beam
- Travels up and down with the boom
- Contacts the ground when the barrier closes
This allows the most appropriate support method to be selected for the installation.

⚠️ Please Note
This listing is for one FAAC Adjustable Beam Fork Support – 428806.
The FAAC 737621 Support Plate for Fork is sold separately unless specifically stated otherwise.
The barrier operator, boom arm, foundation hardware and other accessories are not included.
For B680H installations, the fork support is not compatible with every beam configuration. In particular, FAAC states that the fork, end foot and skirt cannot be fitted to its pivoting round beam system.
The fork should be correctly positioned and adjusted so the boom rests securely in the support when fully closed.
