METAR SUPPORT SYSTEMS METALOK SUPPORT CHANNEL Heavy Duty Cantilever Each Heavy Duty Cantilever has fixing slots to accept the METAR External Flange Clamps (SW/EFC/#), Adaptable Fixing Brackets (SW/AFB/#) and Hold Down Brackets (SW-/HDB/#). The slot pattern allows the adaptable fixing bracket to be fitted either internally or externally on the METAR cable ladder. The heavy duty cantilever arm back plate has a minimum of two 15mm diameter fixing holes (see table below for details) to accept fixings up to and including M14. The loading table below gives the recommended maximum load for each size of heavy duty cantilever arm for supporting uniformly distributed loads (UDL) such as or for supporting Speedway cable ladder (which should be uniformly loaded to apply two equal point loads onto the cantilever arm). METALOK SUPPORT CHANNEL Tray Cantilever Arm The METAR Heavy Duty Cantilever (HDC) provides a specific means of supporting METAR cable ladder on vertical fixed structures or channel (strut type) uprights. The heavy duty cantilevers are available to suit METAR SW4, SW5 & SW6 Cable Ladders for all widths up to and including 900mm wide. METAR SUPPORT SYSTEMS METAR Heavy Duty Cantilever (HDC) (SW/HDC/600 shown) METAR tray arms (TCA) are suitable for supporting cable tray from channel or flat surfaces. Available for cable tray of widths from 50mm to 900mm, the METAR tray arms have M10 clearance holes for fixing to the supports and M6 clearance holes to allow for fixing through the bed of the cable tray. METAR tray cantilever arms have one fixing hole for arm lengths up to & including 100mm, and two fixing holes for arm lengths of 150mm and above. The METAR tray cantilever arms are suitable for use with the full range of METAR cable trays. METAR Heavy Duty Cantilever (HDC) (SW/HDC/300 shown) The loading table below gives the recommended maximum load for each size of trapeze hanger bracket when used with METAR cable tray and with a uniformly distributed load (UDL) onto the tray cantilever arm.
