The USM bal lis a chromium-plated brass ball with six M8x1 threaded holes.
The demand. for high technical quality over several life cycles, close tolerance ranges, dimensional stability, variations in temperature and air humidity, and durability can generally only be achieved with the precise steel material. However, in certain conditions, wood or plastic panels can be used for the horizontal level. Please contact your sales partner.
The dimensions given are the modular dimensions of the USM system and refer to the distance from ball center to ball center. The ball en tubes ar cnnected by a connector (double wedge) whuch is 40 mm long. Two connectors(2 x 40 mm) are required to connect the tube + 2x the distance between the end of the tube and the center of the ball. The USM tube is therefore the shortest possible.
The longer the tube the longer unfavorable the static ratio between tube diameter and tube length. Tubes longer than 750 mm would bend, even under normal weights.
To ensure the high level of USM quality in the whole manufacturing processes and for product liability, our furniture systems are only assembled by trained personnel employed by our sales partners.
The basic ide ais for every product line to be an open system consisting of the same type of materials. The furniture frames are made from chromium-plated and the panels from powder steel respectively. Complex molded parts that are not suitable for mechanical production, for example, fittings, clamping elements and handles are made from plastic injection molding or high pressure metal die casting, depending on the strength required.
The table tops in the USM Haller and USM Kitos ranges are 19 mm ( 8 inch) thick.
Chromium-plated, powder coated and glass elements, as well as all table top surfaces should be wiped clean with a damp cotton cloth and then dried. Glass cleaner or water with methilated spirit ina 10 :1 solution can also be used for more stubbom dirt.
Please note that acetone, cellulose thinner and cleaning agents with strong concentrations of acid or alkali and abrasive particles should never be used on the furniture
