In our opinion, this is the clear favourite among the barriers on the market. The magic and success is always in simplicity. Everything is made of stainless steel, which has a higher strength than ordinary low-carbon steels, and its appearance and function will be preserved for centuries. This is a robust barrier that multiplies the resistance of the door. The bolt itself can eventually be used as a defensive weapon. If someone does not mind having to occasionally make an extra movement to put the barrier on or hang it, this is the obvious choice for a technical solution proven over the centuries.
We also have other modifications for permanent folding of the curtain or its locking or locking.
