T h e BS&B SAFETY H E A D is a simple, easily installed metal rupture disc, held between spe cially designed base and holddown flanges. It positively bursts at predetermined pressure. More than 100,000 of these discs have been burst in the BS&B labora tories to assure absolute precision in over-pressure control. Don't let another day go by without seeing to this basic pro tection for life and property! Write or call Special Products Division, Dept.
