According to General Tools & Instruments, the majestic, elegant tradition of crown moulding dates back to ancient Greece and Rome and is more popular than ever today. The challenge for wood-industry workers has always been the accurate cutting to create seamless corner joints. Well, no more. The new E-Z Pro Crown King makes precise crown-moulding cutting a snap, eliminating trial-and-error and saving money. This product requires no assembly, which the company says is unlike other crown-moulding jigs on the market.
