Telescopic Steel Prop Jack (B461)
Concrete components are supported by movable props. The collar—the threaded part of the prop—is part of it.
The collars are made of high-tensile steel and are galvanized. They may be easily adjusted and are not prone to rust.
Any size prop can be produced upon request. For coarse adjustment,
a steel pin is inserted through a hole in the inner section and a slot in the outer section.
The collar beneath the pin provides the appropriate leveling adjustment.
