Flat Top Plate 18" x 18"
I am very happy with the product you sent me. The person I spoke to really took the time to let me explain what I needed and he sent the exact piece I needed. It fits perfectly and works great. I really appreciate it and will definitly use your site again for future chimney needs!
worked well with the 316TI liner we purchased, although i did purchase some 1/4 inch thick flat metal bars to stretch across the width of chimney then placed the top plate on top of the bars for extra strength to prevent bowing in effect later on down the road from holding the weight of liner over the years. then slapped "hardy-backer" board over top of the top plate and placed my mortar mix on that to create a nice crown for the ridge cap to be placed down in. Top Plate snugs tightly to the liner as you fasten down on the screw fastener
