Modern cubic design meets patented watertightness: MASC water collector box with vulcanized back panel (DN 100)

The MASC water collector box for cubic architectural styles (DN 100) is the forward-thinking roof drainage solution for modern flat roofs, shed roofs, terraces, and parapet connections. On clean-lined buildings in the Bauhaus style, traditional, curved gutter outlets often look out of place. This water collector box combines a clean cubic aesthetic ($240\text{ mm B}\times 150\text{ mm T}\times 300\text{ mm H}$) with superior sheet metal craftsmanship.

The patented highlight is the vulcanized EPDM back panel: Instead of rigid, labor-intensive solder-in outlets, it allows flexible, stress-free connection of pipe diameters from approx. $60\text{ to }120\text{ mm}$. The cutout is simply made approx. $30\mathrm{\%}$ smaller than the pipe's outside diameter – the elastic rubber collar encloses the inlet pipe, providing complete protection against water ingress and backflow. Along with the factory-installed leaf guard and a ventilation grille, the integrated emergency overflow ensures that water is safely discharged to the front during extreme rainfall, instead of flooding the building facade or roof assembly.

The material options at a glance

• Titanium zinc, mill finish (Item no. ZRKV100): The proven classic for standard zinc roof drainage systems.
• RZ prePATINA blue-gray (Item no. ZRKVV100): Factory-pre-weathered zinc, color-matched exactly to RHEINZINK-prePATINA blue-gray.
• VM-ZINC QUARTZ-ZINC (Item no. ZRKQV100): Pre-weathered zinc in the popular velvety quartz gray from VM Building Solutions.
• Uginox stainless steel (Item no. URKV100): Matt-tinned stainless steel for maximum durability in industrial or coastal environments.

Installation tip from a master roofer

Wichtig für die perfekte Dichtigkeit: Den Lochausschnitt in der vulkanisierten Rückwand stets ca. 30 % kleiner als den Rohraußendurchmesser ausschneiden (Beispiel: Für ein Einlaufrohr mit $100\text{ mm}$ Durchmesser wird das Loch mit ca. $70\text{ mm}$ ausgeschnitten). So entsteht durch die elastische Rückstellkraft eine absolut regendichte Verbindung ohne zusätzliches Dichtmittel!

Thoughtful features for the demands of everyday sheet metal work

• Flexible pipe connection: Easily compensates for component tolerances and thermal expansion of parapet pipes.
• Integrated leaf guard: Prevents leaves and coarse debris from entering the $100\text{ mm}$downpipe.
• Effective emergency overflow: Prevents water from backing up onto the roof surface when the downpipe is overloaded.
• Ventilation grille: Ensures unobstructed airflow for optimal drainage rates.
