Profile 45×45 UL Modular Frame System (21.1299/0)

The MiniTec Profile 45×45 UL (part number 20.1063) is a light square 45 x 45 mm aluminium profile in MiniTec’s modular framing system. It is extruded from 6063 aluminium alloy, clear anodised, and weighs 1.445 kg/m, with second moments of area of 9.95 cm⁴ and section moduli of 4.42 cm³ about both axes, which makes it a cost- and weight-saving alternative to the heavier standard 45×45 profile where loads are moderate. Each face has a MiniTec slot for the system’s Power-Lock fasteners, angle brackets and panel mounting elements, and a grey end cap (22.1004/1) closes the ends. Full lengths are 6 m, and MiniTec also supplies custom cut lengths. Typical applications are machine enclosures, safety guards, ergonomic workstations, light frames and fixtures. The part number 21.1299/0 given in the product name follows MiniTec’s numbering for connecting components (21.xxxx) rather than profiles, so it may refer to a connector used with this profile.
