There are differences between the different versions and they are not compatible with each other, especially in width and locking. V2 has also received an updated and improved click system that enables dismantling the short side by angling it upwards, which is very helpful during installation. The previous version, V1, did not have this angling function in the locking system. V2 is manufactured in our new factory lines giving it a different width to V1 and new factory lines also means that the surface treatment differs between the different versions, making them incompatible.
