SEFAR 3A Stretching Clamps

The progressive build-up of the clamping pressure and the lifting function of the SEFAR 3A stretching system enhances its perfor- mance by reducing the reject rate. Why? The mesh can’t slip out the jaws and eliminates friction between fabric and frame.


This means you are able to work with faultless, evenly-stretched screens. Day after day. Another plus point: The SEFAR 3A clamps are suitable for all screen printing mesh – regardless of screen size, materials or thread count. All of this with ease of handling and quick adjustments to the next frame size.
