• The gas spring 2482.73. is an alternative to spiral
compression springs Ø16 and is characterised by a low
force increase.
• These gas springs are color coded to identify different
force ratings: 18, 35, 50 and 70 daN. The springs are all
the same design, the different force ratings being
achieved by different gas pressures.
• The design combines the unique safety features of
FIBRO gas springs: overpressure protection and the
safety psiton rod.
• The upper and lower retaining ring groove, together with
the threaded holes in the spring base, allow for a high
flexibility during the mounting of the gas springs.
• The 2482.73. gas springs have an M6 gas connector in
the base for interconnecting.
