METAR LADDER METAR LADDER METAR 300mm Radius Tees MT MT MT MT EQUAL & UNEQUAL TEES MT MT MT MT METAR Equal Tees (ET) and Unequal Tees (UT) are designed to create perpendicular coplanar connections between horizontal cable runs (ladder installed in horizontal plane) and between vertical cable runs (ladder installed in vertical plane). MT MT MT MT MT MT MT MT MT METAR Tees are available in widths from 150mm to 1050mm as standard. METAR tees are available with standard radii of 300mm, 450mm, 600mm, 750mm, 900mm, 1050mm & 1200mm. Other widths between 100mm to 1500mm and radii, subject to cable ladder type, are also available. MT MT MT MT MT The METAR Tee radial side walls are manufactured with a repeatable and true radius which eliminates the traditional approach of ‘make it fit’ during installation. MT MT MT All METAR Tees are now manufactured with a Metalok Coupler, removing the need for separate couplers in the joining mechanism between cable ladder fittings and straight lengths of ladder. All METAR Tees will be supplied with all necessary fixings. MT MT MT MT The rungs in the METAR Tees are spaced to give a maximum linear distance of no more than 465mm between adjacent rungs/rungs on adjacent ladder and fittings. 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. MT MT MT MT MT MT Tees have a primary or main width (Wm) and a secondary or branch width (Wb). Tees with the same primary and secondary widths are called equal tees. Tees with differing main and branch widths are called unequal tees. MT MT MT MT WHEN JOINING ONE FITTING TO ANOTHER TO SUIT ON SITE INSTALLATION REQUIREMENTS THE USE OF A FITTING TO FITTING COUPLER (FFC) WILL BE REQUIRED.
