The Adjustable Spacer Function
The adjustable spacer was created to bypass many problems which may arise when mounting metal structures such as grates, fences, gates, stairs, and balconies located in cement spaces.
In a very short time the adjustable spacer, welded or placed on the sides of the metal frame, allows to centre the frame in the cement space.
Once the iron structure is centered, it will be fixed by means of standard bolts through the spacer.
The item is composed of two threaded elements, male and female, screwed one on the other to a variable extent; no threaded part of their coupling is visible.
The invention is available in various shapes with extensions from 10 ÷100 mm.
