This image shows the back of the Temptation of St Anthony with the tensioners installed.
Tensioners are used to control and reduce warpage in wood panel paintings, often caused by changes in humidity and temperature.
Tensioners apply gentle and controlled tension to carefully selected points on the painting, thus reducing movement. The tensioner, in its present configuration, is adjustable and can apply from 0 to 200 grams of tension and permit a deflection of up to 4 mm. If the tension is increased, the amount of deflection is decreased.
Tensioners are embedded in a wood strainer that is fitted to the back of the painting. Each tensioner is adjusted by means of a small nut. It is possible to modify the tensioner using a double spring to apply considerably more tension.

is a mechanical design firm involved in the development and fabrication of devices used in the restoration and repair of art objects for over thirty years. We specialize in devices used in the conservation of wood panel paintings.
The tensioner was originally designed with the collaboration of the Wood Panel Conservation Department of The Metropolitan Museum of Art.
Our tensioners have been used by various Conservators in museums in the United States and Europe including The Metropolitan Museum of Art, the National Gallery in Washington DC, the National Gallery in London, the Museo del Prado in Madrid, the Musei Vaticani in Rome and others.
