We want to clear the main technical questions that may arise about the operation of our products and the steps necessary for their assembly.
Hinges
The main function of an unsprung hinge is to allow the use of push pieces to open the door with a push system in order to ensure a smoother opening of the door without the inertia generated by an inverted hinge.It can also be used in combination with soft-close hinges on doors with a great number of hinges in order to accelerate the closing speed of the door, since they are compatible with the entire X91 hinge family.
In the following table you can see the length of the hinge arms on the side of the unit:

The supplements or bases that are used along with the hinges have two holes for fastening to the furniture and a third hole for increasing the resistance of the hinge/supplement joint. It is especially designed for facilities that require more resistance such as on doors with pistons.
The quantity of hinges needs for each door will depend on the width and height of the door, as well as the material that it is manufactured out of. In fact, it can vary in some specific cases.The adjoined diagram can be used as a reference. where L is the distance between the hinges.

Once you have chosen the type of hinge that you are going to use (straight, elbow or super elbow) you will have a formula for calculating the base or plates. This formula will the type B = 14 + D - O, where the variables are: B = Height of the base or plates. D = Drill distance from the hinge. S = Door overlap with the side. For example: We have a door with a thickness of 22mm, an overlap with a side of 15 mm (S) and a distance from the drill of 3 mm (D), we also know that the thickness of the unit board is 16 mm. As the overlap is large, we will use the straight hinge. The formula of the straight hinge is B = 14 + D - O. We know the values D = 3 and S = 15. Replacing in the formula: B = 14 + 3 - 15 = 17 - 15 = 2. So B = 2, with the straight hinge and the base is 2

Depending on the overlap you can choose one of these hinges: Full overlay hinge: If you want to overlap practically the full side of the unit. Half overlay hinge: If you want to overlap half the side of the unit. Insert hinge: If you want the door to be inlaid hand therefore for the side of the unit to be seen.

The following video shows how you can easily install the aforementioned hinge.
Yes, the hinges and accessories come with Ø4x16 mm screws with the same titanium finish.
