DURA-BLOK Rooftop Supports - MARKS SUPPLY

1 DURA-BLOK is made from 100% recycled rubber and qualifies for LEED credits. Reflective strips on both sidesallow for easy product visibility. Channels are through bolted on all sizes for added strength and a 1 ( )gap between blocks allows water toflow freely around longer composition is not sharp or abrasive, helping to extend the roof life and no penetration through the roof DURA-BLOK dampens vibration, needs no supplemental rubber pad, and will not float or blow can be used to support piping, HVAC/Ducts, roof walkways, conduit and cable SupportsAll dimensions in charts and on drawings are in inches.
