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.

WHEN JOINING ONE FITTING TO ANOTHER TO SUIT ON SITE INSTALLATION
REQUIREMENTS THE USE OF A FITTING TO FITTING COUPLER (FFC) WILL
BE REQUIRED. PLEASE REFER TO PG 73 FOR FURTHER DETAILS
