For those who prefer a satisfying thud sound instead of a clang when shutting the grill lid this high temperature seal tape does the trick.
This is entirely an optional upgrade and is not going to give your food lots more smoke or impact the grill temperature stability.
4.5m roll is long enough to do two 700 series Z Grill lids. Comes with 4 washers to raise the hinge brackets up.
