New Stainless Steel Locking Clamp Design
A stainless steel locking clamp is new provided on the board, to lock each connecting board. The 1st generation was buckled together directly by the slotted channel in the board, due to the low strength of the plastic material offering un-sufficient locking strength, in extreme cases these buckles may slip out leads to a risk of failure.
The new stainless steel locking design makes the connection more stable, and doubled the overall rigidity of the full system.

Contacting Interface Reinforced
Reinforcing bracket with the seals is designed at the contacting interface to prevent damage and extend the life.

Storage Space Reduced
The boards can be stored in two or three pieces connected and placed on its side, to reduce the storage area. And the assembled form can reduce the transporting and deploy time for emergency.
