Structurally Attached Supports

Strut Supports

Seismic & High Wind Applications

Utilized in areas where seismic or high wind zones are of concern and where structural design allows for system loads at attachment points. MAPA Products recommends the following Curb Support series and accessories as an effective means by which piping and supports are positively secured directly to the roof deck.

  • The vertical flange accepts a standard 1-5/8" square strut thus allowing mulitple support configurations.
  • The hard cast rubber roller cradles the piping while allowing it the freedom of movement necessary due to thermal expansion of the piping system. Will accommodate up to a 10"IPS. Recommended for Mechanical and Gas Piping.
  • When utilized within the recommended loading limits the strut supports are recommended for securing single or multiple line sets when thermal expansion is not a concern. Recommended for Electrical Conduit and Refrigeration Lines.
  • Single post support is available with 3/8", 1/2" and 3/4" ATR mounting rods providing a 2" attachment point above the shroud or as a single post pipe support assembly sized as specified for the application.
  • Where Rooftop services require structural support; the Utility Pedestal may be utilized. The MPS Series are typically used to construct trapeze support systems, curb and equipment support systems.


Example: MX-5RA9-SA
Structurally Attached Roller Support:
The Structurally Attached Support Series provides a manufactured support designed to secure single piping systems on single ply or built-up roofs in areas where seismic or high wind zones are of concern and where structural design allows for system loads at attachment points.
  • Available with 5”, 8” and 10” Roller.
  • Allows for fewer disturbances to the roof membrane by minimizing the overall flashed area of the installation.
  • Where project design allows, free standing supports may be used in conjunction with structurally attached supports.
  • For increased loading:
    Under deck structural support or reinforcement of roof insulation should be considered.
  • Where Structural Blocking is Utilized:
    Load is transferred directly to the structure; thereby increasing the allowable load, as approved by the structural engineer, any increased loading should not exceed 500 lbs.
