Double-sided stretchers

These double sided stretchers have been specially designed and manufactured to stretch and to present double-sided painted canvases.
The technical challenge of this type of stretcher is that, by definition, it is not possible to use crossbars. The rigidity of the stretcher lies in the correct calculation of the stretcher sections and the quality of the joints.
This unique extension system could be compared to that of an inverted Chassis flottant© (Floating stretcher)
Several parts that can be made as standard creations.
