Q. Is it OK to take out the plastic coated wire that holds together a reed mat and glue the reeds to a 2×4 so that the reeds stay in place and don’t blow away?

Horav Shlomo Miller’s Shlit”a opinion is that the glued reeds may be considered as a solid mass of wood and would have to be then less than four tefochim (32 cm.) wide to be used as schach, otherwise they could be disqualified because of gezeiras tikro, or avoiding the building of a permanent roof.
