BLACK BULL FLEX+ High-Line Impact Protection Railing with Underrun Guard (205.17.951)
The BLACK BULL FLEX+ High-Line Impact Protection Railing with Underrun Guard provides continuous protection from floor level to an overall height of 2870mm. Designed for block storage, high-stacked pallet areas and busy warehouse traffic routes, the raised protective crossbars help prevent stored goods from being struck, displaced or overturned. The integrated low-level guard provides additional protection against forklift forks, wheels and underrun movements. Manufactured from highly elastic polypropylene, the system absorbs and distributes impact energy before returning towards its original shape. It is certified in accordance with PAS 13:2017 and tested to approximately 7,400 joules. Starter, centre extension and corner extension sets are available.



BLACK BULL FLEX+ High-Line Impact Protection Railing with Underrun Guard
The BLACK BULL FLEX+ High-Line Impact Protection Railing with Underrun Guard provides extended impact protection for block storage areas, high-stacked pallets, racking bays and busy warehouse traffic routes.
With an overall height of 2870mm, the system creates a raised protective line that helps prevent workplace vehicles, pallets and moving loads from striking or destabilising stored goods. The integrated underrun guard also protects close to floor level against forklift forks, wheels and low-level collisions.
This combination creates a continuous protective boundary from the floor upwards, helping protect people, stored goods, pallet racking and surrounding infrastructure.
Extended Protection for Block Storage Areas
The High-Line is designed for warehouse and logistics environments where protection is required above standard vehicle height.
Its elevated crossbars help reduce the risk of collisions with stacked pallets and stored goods. They also provide a clear physical boundary between storage areas and internal vehicle routes.
This makes the system particularly suitable for block storage areas, pallet staging zones, transfer points and locations with frequent forklift or tugger train movements.
Integrated Low-Level Underrun Guard
The integrated underrun guard provides targeted protection close to the floor. It helps stop forklift forks, pallet trucks, tyres and other low-level vehicle components from passing beneath the main railing.
By combining raised crossbars with low-level protection, the High-Line provides multi-level protection against collisions, underrun movements and displaced loads.
Flexible Impact Energy Absorption
Unlike a rigid steel barrier, the FLEX+ system absorbs impact energy through controlled elastic deformation.
During an impact, the polypropylene components flex to cushion the force and distribute it across the complete protective line. Once the impact force is removed, the system returns towards its original shape.
This helps maintain the protective function while reducing permanent deformation, repair requirements and operational disruption.
PAS 13 Certified Performance
The BLACK BULL FLEX+ High-Line with Underrun Guard is certified in accordance with PAS 13:2017 and tested to an impact load of approximately 7,400 joules.
Its flexible construction and wide-area force distribution help reduce concentrated loads on individual posts, floor fixings and structural components.
Raised Crossbars and Supporting Posts
The highly elastic polymer crossbars form a continuous protective line across several height levels.
They help prevent vehicles, pallets and moving loads from entering protected storage areas or causing stored goods to shift or overturn.
The supporting posts receive and distribute the transmitted forces throughout the full height and length of the system, helping maintain stability across the protective run.
FlexLink Connection Technology
FlexLink connection technology distributes impact forces between adjoining crossbars, posts and barrier sections rather than concentrating the load at one point.
This helps reduce pressure on individual components, anchors and the surrounding concrete floor. It can also help minimise loose posts, damaged fixings and consequential substrate damage.
Impact-Resistant FLEX+ Bases
Each FLEX+ Base connects the vertical post to the ground anchor and incorporates an impact-resistant outer shell.
The base protects the internal screw connection from direct contact and everyday operational damage. Its shaped design also helps reduce the risk of damage to the tyres and wheels of forklift trucks and pallet trucks.
Force-Absorbing Ground Anchors
The FLEX+ Base ground anchor combines secure concrete anchoring with integrated force-absorbing rubber dampers.
These dampers help reduce the loads transferred to the fixing connection and floor substrate during an impact. This supports a stable bolt-down installation, even in areas where repeated contact may occur.
Designed for Repeated Impacts
The highly elastic polypropylene construction is designed to remain functional following repeated knocks and minor collisions.
Its ability to flex and recover can help reduce permanent damage, replacement costs, maintenance requirements and operational downtime in busy warehouse environments.
Modular High-Line Protection System
The BLACK BULL FLEX+ High-Line with Underrun Guard is available in three modular configurations. The Starter Set creates an individual section or the beginning of a longer protective run, while the Centre and Corner Extension Sets allow the system to be expanded.

Protection for Goods and Infrastructure
The BLACK BULL FLEX+ High-Line with Underrun Guard is designed for areas where standard-height barriers may not provide sufficient protection.
Its raised crossbars help protect stacked goods and storage structures, while the integrated floor-level guard helps stop forklift forks and low-level vehicle components from entering the protected area.
