It may look like a solid mahogany beam, but the Precision Frames made by this Vermont company are really 1/4-inch veneer applied to laminated timbers. The company has a unique fastening system that uses concealed bolts so nothing mars the look of the mahogany. The timbers are available in lengths up to 18 feet, but the only real limit is the length of the veneer. The price is a little more than twice what typical laminated beams would cost, but the value is in the popular look of mahogany. Contact: Green Mountain Precision Frames, P.O.
