positioned within the duct system to prevent the free passage of smoke &amp; fire. The range is 

constructed from heavy gauge galvanized iron sheet having multiple opposed blade construction. The 

blades are fitted with crome plated spindles operating in self lubricating sintered bronze bushes with 

stainless steel side seal gaskets to prevent spread of smoke &amp; fire. The operating linkage is 

fully enclosed.</span></p>
