Weil-McLain has begun the expansion of its Product Engineering Lab. The $1,250,000 project is set for completion in the fall of 2001. Tonn & Blank is the contractor in charge of completing the new facility, which will almost triple the size of the old lab, taking the overall square footage from 3,500 sq. ft. to 9,500 sq. ft., and increasing the number of test bays from 7 to 14.
