The Mutual Power aluminum swivel clamp SC-201 clone history:

In May 2000 the Mutual Power's supplier (Xpider Co.) copied Eagnas PN-1008 aluminum swivel clamp design. Use the Eagnas PN-1008 aluminum top and bottom parts. Use the Eagnas PN-1008 steel post. Add the steel handle and metal thumbknob. But Mutual Power indicates it is a stainless steel clamp to mislead the viewers. (Click on model number to view larger image.)

1997 Eagnas PN-1008 Price: $17.95		May 2000 Mutual Power SC-201 Price: $69.95
