FAQs
Installation starts by aligning the extension ring with the device box mounting surface, ensuring the 15 mm plaster compensation is engaged to accommodate wall variations. Secure it to the wall box per standard flush-mounting practice, then assemble the device box and cover. The result is a neat, recessed finish that maintains wiring accessibility and protective clearance.
Key specs include 49 mm net width, 34 mm net height, and 75 mm net depth, with a mass of 0.011 kg. It is designed for built-in installation boxes and flush mounting, with plaster compensation of 15 mm. Packaging is bagged in units of 50, and it aligns with ETIM EC000115 classifications.
Yes. The extension ring is specifically described for flush mounted brick wall junction boxes and built-in installation boxes, making it well suited for industrial enclosures and panel installations where a clean, recessed finish is required and plaster variation must be compensated.
The product carries CE declarations and REACH compliance, and CMRT coverage is provided to support responsible sourcing. This helps meet regulatory obligations and supplier-qualification criteria in many industrial procurement programs.
The extension ring reduces field rework and installation time by providing a ready-made plaster compensation solution, which lowers labor costs and fault potential. Its predictable packaging and compatibility with ABB plaster compensation rings simplify stocking and project planning, delivering faster project completion and fewer call-backs.
