An extender crossbar increases the inner height by 145 mm – E4.1L.

… enormously variable … enlarged …

A clamp crossbar increases the inner height of the chain series E4.38L and E4.48L by 48.5 mm per side. The extender crossbars can be mounted in different ways: one-sided, both sides, alternated with standard crossbars or any combination of the above.
Typical applications:Wood working machines, tool machines, air extraction systems, coating plants, general mechanical engineering
