A method of installing a vibratory shaker screen in a vibratory shaker, comprising:
- placing a first end of the vibratory shaker screen in contact with a first retainer of the vibratory shaker;
- deflecting a tab located on a side member of the vibratory shaker screen through contact of an angled surface of the tab with a second retainer of the vibratory shaker;
- and
- connecting the vibratory shaker screen to the vibratory shaker, wherein a lock surface of the tab is positioned in contact with the second retainer such that the vibratory shaker screen is fixedly attached to the vibratory shaker.
A vibratory shaker screen, comprising:
- a mesh supporting system including at least one tab disposed on at least one side member, the tab configured to move from a first position to a second position, the at least one tab configured to move to the second position upon placement of a force on the at least one tab by a retainer of a vibratory shaker, and the at least one tab further configured to return to the first position upon removal of the force to engage a lock surface of the tab with the retainer;
- and
- at least one mesh portion disposed on the mesh supporting system.
A vibratory shaker screen, comprising:
- a mesh supporting system having a top face and a bottom face, the mesh supporting system forming a frame with at least one side of the frame including at least one tab extending from the at least one side of the frame, wherein the at least one tab is configured to deflect from a first position to a second position upon placement of a force upon the tab by a retainer of a vibratory shaker, and the tab is further configured to return to the first position upon removal of the force to engage a lock surface of the tab with the retainer;
- a first mesh portion connected to the top face of the mesh supporting system;
- and
- a second mesh portion connected to the bottom face of the mesh supporting system.
