For sizes R 15 45: Fixation by means of 2 to 4 persistent threaded bars (sizes R also available with threaded holes). Friction locking of the core by means of one central bolt, can be positioned in full 360 angle-range. For ideal friction locking, please remove paint cover on face side. For alternating el ement motion of max. ±10. For plug-in connection with square profile*. Plug-in length min. 2 x width across flat C. Connection is not recommendable by alternating motions play between the plugged squares. * The square should be made out of bright steel, tolerance h9 h11. Possibly, the edges have to be overwinded (edge-radius in element profile max. 1 / 16 inch). pecification R- 15 x 25 ize Inner square Housing Effective element length General ight metal profiles: extruded profiles, seawater resistant (IN 1725). lue protection paint: water-soluble paint, coating thickness in. Fixation screws: minimum strength class of 8.8 Welding on elements: do not weld on rubber suspensions welding heat will affect or destroy the rubber inserts ask for customized elements Most of the elements can be supplied in stainless steel version also zinc-plated versions or special paintings are available Further customized elements: see examples on page 1.14 to 1.19.
