ABSTRACT:
A frame for a mesh machine guard, or a pane of plastic, has a four-sided configuration, each side being formed of an extruded relatively rigid material having a channel shaped configuration, and an insert in each channel. Each insert is formed of a relatively soft resilient material and has one or more opposed flanges inclined in the direction in which the mesh is inserted in the frame. The resilient flanges wedge the mesh or pane in position in the insert to prevent the removal of the mesh or pane.
