<strong>Yahoo Message Number: 67430</strong>Does anyone out there know how think the plywood subflooring is? I am getting ready to install a new sofa. The old one was secured to the floor using 1/4 X 1.5 inch long lag screws, and I was hoping to do the same with the new one. Just wanted to make sure I did not drill through any wiring. <br/>Thank you,<br/><br/>Brian 97 Intrigue #10373
