ឧបករណ៍កាតព្វកិច្ចស្រាល are used for supporting work in buildings construction, with working height range from 0,50-0,80 m up to 3,00-5,50 m.

Two end plates, upper and lower plates, serve to give stability to the steel prop.

The inner tube is Ø 48mm / 40mm (thickness from 2 mm to 4.0mm) with holes to adjust the working height with help of the pin.

The outer tube is Ø56mm / 60mm (thickness from 1.6 mm to 2.5mm).

The pin diameter is between 12 and 14 mm, with a special design that does not allow its fall.

The thread is covered by a cup-type nut (internal thread) that has 2 side handles for easy handling (Cast nut with external thread is also available.).

A steel ring plate is also equipped on the nut that prevents concrete materials falling into the nut and get stuck.
