Experts in fittings for double-winged door systems

Drive bolts and flush bolts for doors & gates

Bolts for inactive door leafs in double winged door systems: For just about any assembly situation DENI^® has the suitable product.

Products such as DENI VARIO, DENI PLANO and DENI PORTA have long been recognised to stand synonymously for reliable quality made in Germany, a wide variety and functional design.

We are looking forward to showing you at our trade show booth, how easy it is to change the DENI VARIO door drive bolt’s direction of rotation, why DENI PLANO stands for high-quality material and workmanship or which countless flush bolt models for metal, wooden and plastic profiles we also provide.

DENI SVG is a highly effective rod lock for the lock side of windows and French windows.

Slim aluminium profiles with high quality treated surfaces are available in four standard colours and many possible special colours. Moreover, they impress with their visual unobtrusiveness on the sash.

The rod lock is activated by the normal use of the window handle. While the window is closed, the bolts are driven out both up- and downwards. That way, the extended bolts provide two additional safety points.

The special feature, in particular, is:
Also in the tilted state of the window DENI SVG remains partly active. 
Thus, the lower bolt stays extended downwards. Considering the fact that, according to statistics, more and more burglaries take place during the day and while people are in the house, this special tilt protection provides a higher level of protection. The levering out of the sash window while a room is ventilated becomes significantly more difficult for the perpetrator.

Retainers and buffers for doors & gates

The product portfolio of this segment provides models made of light alloy, malleable cast iron or stainless steel for mounting at doors, walls or floors, in classic or modern designs, for doors and gates of different sizes and weights.

The DENI ROBUSTO series is ideally suitable for retaining and buffering of extremely heavy doors and gates, depending on the model, for doors and gates of up to 120 or even 200 kg.

The model DENI ROBUSTO DUO+ for floor mounting combines the functions of retaining and buffering in an extremely solid and sturdy stainless steel housing. A release slide mechanism combined with a foot pedal ensures high operating comfort.
These features turn the proven DENI ROBUSTO DUO+ into a perfect fitting solution for tough conditions such as in the public sector or in cooling areas.

The automatic one: DENI HZ

DENI HZ allows to open and close double-winged door systems silmutaneously with just one hand.

DENI HZ turns double-winged doors into attractive comfort doors with an added value for high-demand users. The comfortable automatic mechanism is achieved by the special geometry of the patented latch.

The DENI HZ series provides models for all fitting situations, both for wooden or for metal profiles. The series also includes complementary items such as manual and semi-automatic flush bolts and accessories, which can be combined.

At our booth we will be more than happy to inform you extensively about this product range and to show you how the DENI HZ works.
