MOD CLS
The MOD CLS is an adjustable lifting beam / spreader beam, consisting of a beam section and beam
clamps that lock onto the flange of the beam section. The MOD CLS can be readjusted to achieve the exact
required spans of any lifting configuration by simply altering the quantity and position of the clamps.
