Mounting Extensions with adjustable stroke, L series
Presentation
The L series extensions are used for gripping on various levels from the same installation plate. These extensions are adjustable to different heights.

This system is especially useful for 2.5 bellows-type suction cups, as height adjustment is made easier by the deflection of the suction cup.

Spring systems should be chosen, instead, for flat suction cups with low deflection.
Materials
• Threaded rod and nut: Brass
• Screwed vacuum fitting: Nickel-plated brass
