Speedball, the #1 name in printing, manufactures this standard, pre-assembled screen printing unit. The 110 monofilament polyester screen fabric is stretched and cord-locked in the frame grooves. The fabric can be tightened or replaced as necessary. 10x14" wood frame has glued corners reinforced with corrugated metal fasteners for added stability. It's mounted with hinges on a 1/4" thick masonite printing base for ease in use. Kick leg keeps fabric in place and assists in registration. A super choice for the classroom.
