"Comb was easy to fit, and rigid enough to fill the arches in the tiles perfectly. Tiles rested fully down onto the nailed surface. Pre-formed holes made it easy to line up nails to punch through the felt support tray underneath, and notches in the ends made it easy to line up each section of comb. I used 40mm galvanized clout nails (11541) into 18mm upvc fascia board. You need to use large headed nails to make sure the comb and tray are held squarely and tightly to the top of the fascia."
"Easy to fix but difficult to get tile to sit on comb. Had to move tile back and forward while putting full body weight on top of tile to compress combs to allow tile to sit in place. Overall does what its supposed to do"
