I need to support six (6) 2'' beams by heavy duty lolly columns and I am looking for a large, 12''x12'' lolly column head plates (or caps). Where can I find such plates? HomeDepot only sells small 4''x4'' plates. I am located in Massachusetts.
P.S. This is for new modular construction. 3 beams come from each module giving alltogether 6 beams of the total width 12 inches. Thanks.
