Adapt-A-Block Benefits

The GAB1 plastic rooftop block from G-STRUT® provides a single block or interlocking, multiple base system for roof block variations to accommodate heavier applications and high-wind locations. Pipe grooves facilitate alignment and stabilize the conduit and pipes, while a self-locking nut feature allows quick installation.

  • Easy storage with stackable design

  • Even weight distribution for greater load-bearing capacity once strut is attached

  • Water drainage through sloped edges and bases

  • Easy to assemble the nut to fastening rods or bolts

  • Numbered pipe grooves align for organizing pipes

  • Quick clamp to 2” pipe with perforated metal strap or universal strut

  • ½” diameter holes with self-locking nut to accept extension rods, rise clamps and struts

  • Blocks interlock to connect in a series; many options for pipes to be secured to a series

Strut Attachment

Easily attach G-STRUT® channel directly to Adapt-A-Block with sheet metal screws and washers. For heavier applications, use ½” bolts.

  • Self-locking nut feature for quick installation

  • Use the included perforated metal strap to secure the pipes

  • Use numbered pipe grooves to align quickly and easily

  • Screw both ends of the metal strap using sheet metal screws and following the included screw guides

Riser Rods Adapt-A-Block can be used with up to 12” riser rods, placed in any combination of the three ½” diameter holes. Once attached, riser rods can be adjusted from 8.5” to 10.5”.
