Height adjustment ring/-frame for underfloor install. duct

Height adjustment rings and frames for underfloor installation ducts are precision-engineered components designed to align floor-level distribution systems with finished floor surfaces. These products typically feature adjustable height mechanisms, robust metallic or high-grade polymer construction, and compatibility with standard underfloor duct systems. They ensure proper load distribution, IP protection ratings (e.g., IP44 or higher), and seamless integration with floor coverings. Common technical specifications include diameter ranges, load-bearing capacities up to 500 kg, and corrosion-resistant finishes. These rings and frames are essential for achieving flush, safe, and accessible installations in commercial and industrial environments.

These components are primarily used in underfloor duct systems for power, data, and communication cabling in office buildings, data centers, hospitals, and industrial facilities. They are installed in raised floors, concrete slabs, or modular flooring systems to provide adjustable access points for cable management. Applications include distribution boxes, floor outlets, and junction boxes where height adjustment is critical for matching varying floor thicknesses or surface finishes. They are also employed in renovation projects to retrofit existing underfloor ducts to new floor levels.

Key subcategories include height adjustment rings (e.g., models with 100-200 mm adjustment range), frames for flush mounting, and complete adjustment sets. Common article codes often follow patterns like "HAR-XXX" or "UFD-ADJ-XXX" where XXX denotes diameter or load rating. For example, codes such as HAR-150 (150 mm diameter) or UFD-ADJ-300 (300 kg capacity) are typical. These products are available in various materials, including galvanized steel, stainless steel, and reinforced plastic, with options for screw-adjustable or spring-loaded mechanisms.
