The history of the GU (Gretsch-Unitas) brand began back in 1907 in Germany, when the enterprising engineer Victor Grech began producing simple fittings. Soon businessman Johann Maus became Grech's partner.
In the 1920s, the company began to actively expand its product range and enter the world market. Gretsch-Unitas was badly damaged by World War II, and in 1948 the company had to rise from the ashes, which in this case is not just a common phrase. In the 1970s, other manufacturers joined the company.
GU's philosophy is based on continuity - it is now run by Maus' descendants, Julius and Michael von Roesch.
Nowadays, GU fittings meet all modern requirements - from service life to environmental safety. The company has its own research center, which searches for new technological solutions.
In 2007, the brand celebrated its centenary. In Russia, fittings of this brand appeared in 1996. GU has established several warehouses in our country and cooperates with many sellers.

Who are the consumers of GU fittings?
GU fittings – for the middle class
These are high-quality fittings, but the prices for them cannot be called exorbitant. Of course, it will be more expensive than Russian brands, but not by much. For example, a handle that can be locked with a key will cost 350 rubles. Opening limiter only 60 rub.
Mosquito nets produced by GU cost about 700 rubles. per m2. With fittings from the UNI-JET line, the matter will depend on the standard configuration and the number of additional gadgets - the price varies from the “economy” option to the “extra” option.
Any representative of the middle class can afford GU fittings: they are of high quality, but not elite.

Hard to find

The fittings break

There is a lot of dissatisfaction on the Internet that some parts of the fittings have become unusable. For example, on the okna-firm forum, user Lelik comments on the possibility of replacing individual broken parts: “If the fittings were good, then there would be no need to change them!”
From numerous reviews we can conclude that the fittings do sometimes fail. It seems that if you install more expensive fittings, the likelihood of breakdown will be reduced.
