HELPING ENERGY STORAGE TEAMS UNLOCK MORE VALUE FROM EVERY ENCLOSURE

For battery energy storage projects, every design decision can influence system performance, project economics and long-term serviceability. While enclosure specifiers often prioritise cells, thermal systems and fire protection, latching hardware can also play an important role in how storage systems are designed, installed, maintained and protected over time. Traditional vertical rod latches are commonly included as a standard option, which can make it difficult for asset owners and design teams to see the value of upgrading the latch system.
Southco’s F2 multi-point latch is designed to address the everyday challenges that traditional enclosure latching systems can create for the people who design, transport, install and service energy storage enclosures. Rather than treating latches as a low-cost commodity, F2 helps teams solve practical application challenges tied to enclosure space, logistics, maintenance, sealing, security and safety.
Designing Enclosures Around Space, Not Hardware Constraints
For enclosure designers, space utilisation is directly connected to energy output, layout flexibility and project profitability. Traditional vertical rod latches can create difficult tradeoffs because their protruding locking bars must be mounted either inside or outside the enclosure. Each approach can introduce added cost or design limitations.
Vertical Rod Latches for a Traditional Enclosure
When rods are mounted externally, they can increase the overall enclosure footprint, reducing container loading efficiency and increasing freight, port and customs-related costs during transport. When rods are mounted internally, they can take up valuable enclosure space that could otherwise support battery cell modules, limiting cell density and reducing enclosure capacity.
The F2 multi-point latch gives design teams a more compact alternative. With a significantly slimmer 30 to 50 mm profile compared with conventional vertical rod hardware, F2 helps reduce external bulk while supporting more efficient internal layouts. This gives engineering and design teams more flexibility to optimise enclosure space, improve cell density and support stronger overall project economics.

Making Service Work Easier for Field Teams
Energy storage enclosures are built for long service lifespans, but the people maintaining those systems often deal with the hidden labor and ergonomic challenges created by traditional door hardware. Over time, heavy doors, tight-tolerance rods and enclosure deformation can make access more difficult, slowing inspections and increasing service effort.
Traditional vertical rod latches may require two technicians to operate heavy doors during inspection and maintenance. F2 is designed with a 13:1 mechanical advantage, supporting easier single-handed operation and helping reduce on-site labor time for service teams.
F2 also supports more reliable access as enclosures age in outdoor environments. While traditional vertical rods can jam or lose sealing when doors sag or deform, F2 maintains smooth latching and full sealing with up to 6 mm of door deformation. This helps reduce recurring adjustments, spare replacements and maintenance-related costs over the life of the enclosure.
Supporting Safer, More Reliable Energy Storage Sites
For asset owners and operators, enclosure hardware also plays a role in protecting equipment, maintaining environmental sealing and reducing site-level risks. Exposed rod lock points can be more vulnerable to prying or unauthorised access, while concealed multi-point locking helps secure the door across multiple positions and resist forced entry.
F2 also delivers uniform 12 mm gasket compression to achieve an IP66 rating, helping protect enclosures against rain, dust and coastal salt fog while extending hardware lifespan. For storage sites exposed to demanding outdoor conditions, this added sealing performance helps protect the system and reduce long-term reliability concerns.
Helping Contain Pressure During Thermal Runaway Events
In battery energy storage applications, thermal runaway can generate intense internal pressure that may compromise enclosure doors. Traditional vertical rod latches concentrate that force at only two locking points, which can make the door more vulnerable underload.
F2 helps distribute force more evenly across the enclosure frame through multiple latching points. Each F2 latching point supports more than 5,000 N of load, helping the enclosure better manage internal pressure during a thermal event and reduce the risk of hazards spreading beyond the enclosure.
A Smarter Upgrade for the People Behind Modern Energy Storage
As energy storage systems move toward higher density and stricter safety requirements, enclosure hardware must do more than simply keep doors closed. It must help design teams make better use of limited space, support service technicians in the field and give asset owners greater confidence in long-term performance.
Southco’s F2 multi-point latch provides a practical upgrade for modern energy storage enclosures by improving space efficiency, streamlining serviceability and supporting reliable environmental sealing. With a relatively small upfront hardware change, F2 helps deliver long-term value through reduced lifecycle costs, improved usability and stronger enclosure-level protection.
