METAR LADDER METAR LADDER The rungs in the METAR Horizontal Bends are located radially at either 0° or at 7½° incremental angles (or multiples thereof) and are passed to give a maximum linear distance of no more than 465mm between adjacent rungs on adjacent METAR Cable Ladder and METAR Cable Ladder Fittings when measured along the outer radius. HORIZONTAL BENDS METAR Horizontal Bends are designed to create fixed angular coplanar connections between horizontal cable runs (cable ladder installed in horizontal plane) and between vertical cable runs (cable ladder installed in vertical plane). The rungs are orientated with the open face uppermost to suit the use of cleats and similar cable restraint devices. This allows compliance with current recommendations for cable restraint, especially where cables are used which have a high potential fault current level. METAR Horizontal Bends are available in widths from 150mm to 1050mm and angles at 30, 45, 60 and 90 degree as standard. The standard radii are 300mm, 450mm, 600mm 750mm and 900mm. Other widths between 100mm to 1500mm and radii, subject to cable ladder system type, are also available. The number of rungs shown in the METAR Horizontal Bends, left, are based on the standard 300mm wide and 300mm radius flat elbows. Refer to the dimensional information tables for the number of rungs for other widths and radii. The METAR Horizontal Bends are manufactured with a repeatable and true radius which eliminates the traditional approach of ‘make it fit’ during installation. All METAR Horizontal Bends are manufactured with a METALOK Integral Coupler, removing the need for separate couplers in the joining mechanism between cable ladder fittings and straight lengths of ladder. Fittings can be supplied without Integral Coupler if required. All METAR Horizontal Bends will be supplied with all necessary fixings for fixing the elbow to the straight length. The rungs are orientated with the open face uppermost to suit the use of cleats and similar cable restraint devices. This allows compliance with current recommendations for cable restraint, especially where cables are used which have a high potential fault current level.
