Description
FAAC L Beam Pocket & Spring – B680H – 428437
The FAAC L Beam Pocket & Spring is the genuine combined beam mounting pocket and balancing spring assembly designed for use with Round L beams on the FAAC B680H Hybrid Barrier Operator.
The 428437 provides the mounting and counterbalancing assembly required when configuring the B680H with the larger Round L beam system, which FAAC specifies for passage widths from 5 metres through to 8 metres.
FAAC Part Number: 428437
⚙️ Combined Pocket & Balancing Spring
The 428437 combines the components required to mount and correctly balance a Round L beam on the B680H.
The assembly provides:
- L beam mounting pocket
- B680H L balancing spring
- Associated mounting components
The balancing spring counterbalances the weight of the boom, reducing the load on the hydraulic drive system and allowing the B680H to provide smooth and controlled movement.
📏 Designed for Round L Beams
FAAC specifies the 428437 specifically for the B680H Round L beam system.
Round L beams are used for B680H installations with effective passage widths from 5 metres through to the maximum 8 metres supported by the barrier.
The L beam system includes both whole and modular boom configurations depending on the required length.
🚧 B680H L Beam Configurations
FAAC’s Round L beam range includes:
- 428047 – Whole Beam L 5.3m
- 428048 – Initial Beam L 4m
- 428049 – Final Beam L 2.3m
- 428050 – Final Beam L 3.3m
- 428051 – Final Beam L 4.3m
- 428616 – Joint L
The modular L system allows the B680H to be configured for longer passage widths by connecting an initial and final beam section using the dedicated 428616 Joint L.
💡 Accessory Allowances
FAAC specifies different accessory allowances according to the effective length of the Round L beam.
For B680H L beam configurations:
- 5m to 7m – lights, skirt and end foot permitted
- 7m to 7.5m – lights permitted, with either skirt or end foot depending on configuration
- 7.5m to 8m – lights and end foot permitted, but skirt not permitted
These restrictions are important because accessories fitted to the boom affect its overall weight and balancing requirements.
🔧 B680H Specific Component
The 428437 is specifically designed for the FAAC B680H barrier system.
The B680H operator does not include the beam pocket or balancing spring. These are selected separately according to the beam system being installed.
For B680H Round S beams:
- 428436 – S Beam Pocket & Spring
For B680H Round L beams:
- 428437 – L Beam Pocket & Spring
FAAC also uses the 428437 in its own example B680H installation with an 8m modular L beam configuration.
