The very economical Model 420 was introduced in 1999, and fabricators from coast to coast have been very pleased with its operation. The Model 420 will camber grade 50 beams as large as a W30x116. Unless the fabricator does bridge work, this model should satisfy 99% of his cambering requirements.
In 2001 the Model 520 was added to the line. It has 25% more cambering capacity but only costs about 12% more than the 420. It will camber a W30x148.
