Frequently asked questions


The cup acts as an indispensable element of the UniBlock system, providing a solid and secure connection between the brackets and the horizontal wooden panels. Its design facilitates assembly without compromising the stability of the furniture.

It is specifically designed for panel thicknesses between 16 and 19 mm. Its depth and internal geometry are optimised to ensure a perfect fit of the support inside the wood panel.

The cup combines a plastic body that provides insulation and lightness, together with a zamak reinforcement in the anchorage area, which improves mechanical resistance and prolongs its durability over time.

Installation requires drilling a Ø20 mm hole in the vertical panel to a depth of 13 mm, normally carried out with a CNC-controlled drill or automatic machinery to ensure mounting accuracy.

Delivered in packs of 2,500 units, it is ideal for large-scale production environments, industrial joinery or distributors requiring volume and logistical efficiency.
