DOUBLE-ACTION PROPS (“PUSH-PULL” TYPE)
The push-pull props are a derivative of Class B props, retaining all their safety features and load-bearing capacity.
These props are designed to work under both compression and tension, offering a cost-effective solution for installing vertical formwork systems and timber panels, ensuring their stability during concrete pouring.
They are also widely used in pre-assembly operations, where they provide reliable support for vertical wall elements during installation.

-
-
Adjustment system: either with collar or external self-cleaning nut.
-

Features
-
Round hinged bases:
Equipped with oval holes that make positioning safer and easier during installation. -
Safety system:
When fully closed, the prop ensures at least 10 cm of free inner-tube length, preventing accidental hand injuries from compression. -
Perforated holes:
Burr-free machining guarantees smooth operation and full functionality even after repeated use. -
External thread:
Produced by rolling (not cutting), ensuring material integrity. The long thread length allows for fine height adjustment and includes two self-cleaning round steel nuts for easy operation. -
Internal thread:
Also rolled, then welded to the outer tube, ensuring high strength and reliability. -
“Push-pull” steel coupling:
The upper section of the tube provides the push-pull effect, while simultaneously protecting the internal thread. The deformation at the lower end prevents accidental detachment from the thread.
