<p>The device has a plane rigid surface (1) supported by supports (2), where the supports are intended to rest on a work base, and the supports allow the rigid surface to be raised. The supports allow the rigid surface to be placed above fixed elements embedded in the work base, where the device is movable laterally to various places with respect to the work base by a simple push, and the supports prevent the rigid surface from slipping ahead or behind the work base. The rigid surface is made from one of tile, melamine, or wood.</p> |
