RESPECT WITH THE STANDARD ACCESSORIES MARKET
The products can be adapted to any common lock out in the market with the prefabrication of some special components:

Special square rotating pivot axis with the standard cross-section who will be able to host allen bolts and the possibility of related reduction and increase in response to the different door thicknesses. The apparent axis in the working parties will have the same surface treatment as the apparent remaining parts.

A special very thin rotation washer in connection with the door knob. If we are to function as spring-loaded handles on the market, it should be designed to fit into a recess within the thickness of the handle and be a part that is not available on the market according to our knowledge, ready at very small dimensions required by our design.
