STAUFF Multiple Weld Plate (Type RAP-MGR – Standard Series)
The STAUFF Multiple Weld Plate (Type RAP-MGR – Standard Series) is designed for serial fastening with Group 2 clamps (8-18 mm) and Group 5 clamps (20-42 mm). A single plate covers diameters from 8 to 42 mm, optimising installation in hydraulic systems. It can be configured with 6 to 27 integrated weld nuts, with metric (M6) or UNC (1/4-20) threads and material options in W1 carbon steel or W5 stainless steel. The available product codes (complete standard family in W1) are: RAP-MGR-25-156-M-W1, RAP-MGR-25-156-U-W1, RAP-MGR-25-234-M-W1, RAP-MGR-25-234-U-W1, RAP-MGR-25-312-M-W1, RAP-MGR-25-312-U-W1, RAP-MGR-25-390-M-W1, RAP-MGR-25-390-U-W1, RAP-MGR-25-520-M-W1, RAP-MGR-25-520-U-W1, RAP-MGR-25-700-M-W1, RAP-MGR-25-700-U-W1.
The STAUFF Multiple Weld Plate (Type RAP-MGR – Standard Series) is an essential technical component for the multiple and serial fastening of rigid and flexible tubing within complex hydraulic and fluid power circuits. Specifically designed to interface with STAUFF Standard Series clamp bodies, this multiple plate provides an extremely versatile mounting solution for industry professionals.
The key technical feature of this component lies in its ability to simultaneously support STAUFF Group 2 clamp bodies (standard models) and STAUFF Group 5 clamp bodies (Type MGR). This makes it possible to cover an extremely wide range of tube outside diameters, from 8 mm (0.31 in) up to a maximum of 42 mm (1.65 in), using a single weld-on base. Specifically, for Group 2, the covered diameter ranges from 8 mm to 18 mm, while for Group 5 (Type MGR), the supported diameter ranges from 20 mm to 42 mm. The use of a single plate type for different diameters simplifies procurement and standardises installation. In addition, all Standard Series metal components, such as bolts and cover plates associated with these groups, are fully compatible.
The dimensional specifications of the plate ensure strength and installation modularity. The plate width (B) is fixed at 30 mm, with a thickness (S) of 4 mm. The distance between the centres of the weld nuts (L3) is precisely calibrated at 26 mm (1.02 in). The plates are available in different total lengths (L4), depending on the number of integrated weld nuts. The system starts with compact configurations featuring 6 weld nuts (length 156 mm), then scales up to 9 nuts (234 mm), 12 nuts (312 mm), 15 nuts (390 mm), 20 nuts (520 mm), and finally the largest configuration with 27 weld nuts (length 700 mm).
Regarding fastening options, the weld nuts are available with two thread variants designed to meet different international standards: ISO metric M6 thread (Code M) or Unified Coarse 1/4-20 UNC thread (Code U).
The construction materials selected for the STAUFF Multiple Weld Plate (Type RAP-MGR – Standard Series) reflect the need to operate in demanding industrial environments. The standard option (Material Code W1) uses uncoated carbon steel, ideal for direct welding onto supporting structures. For applications requiring high corrosion resistance, a V4A stainless steel version (Material Code W5) is available upon request, compliant with grades 1.4401 and 1.4571 (AISI 316 / 316 Ti).
