Locking Gas Struts - Blocklift

The Blocklift can be stopped at any position during operation, being fitted with a locking valve they only allow movement when the release pin is pressed.

Locking Gas Struts in a Range of Sizes

Locking gas struts come in four types – rigid in extension (where it acts in an elastic manner if compressed, but is rigid when extended – found in steering columns for example), rigid in compression (the same as rigid in extension, only working the opposite way – found in reclining seats for example), spring blocking (where it is elastic in both directions – found in office chairs for example) and rigid in extension and compression (rigid both ways, offering no elasticity. Can be found in any of the previous examples where rigidity is required in both directions).

 Type Description  Gas Strut Size Range
8-23 10-23 10-28
BL1 Rigid in extension Y Y Y
BL2 Rigid in compression Y Y Y
BL3 Spring blocking Y Y Y
BL4 Rigid in extention & compression Y

Most Blocklift gas struts are available in 316L stainless steel and a wide range of hydraulic, cable, traction and lever release systems are available for these useful locking gas springs.
