-My invention relates to improvements `in roof drains. and has for one kobject to pro-` vide anew and improvedr form of roof drain with a. positive rigid and secure clampingA of the roofing fabric. Another objectisto provide a device wherein the clamping posts are fully protected from Weather' and traf'- fic, to provide a dome strainer which cannotbe blown or` knocked over, topi-Ovide a '10 body design which eliminates the possibility Qof airv pockets,

which yisl in itself self-*cleanjing7 .wherein the clamping means and the" Y strainer are to a maximum extent free'from A.rusting or freezing inplace., Another obaperture 4or Aperforation through the fabric `V20 'f 3 `of Figure 2; f y:-
