Erico PYRAMID Universal Support 5.5" x 4" PBU6

Reference#: 73588
Item#: PBU6


CADDY® PYRAMID rooftop supports are a surface mounted solution for supporting electrical and mechanical applications on a variety of roof surfaces. They offer superior load capacity and dramatically reduce installation time by replacing slow, heavy and labor intensive methods for support of pipe, conduit, duct, cable tray and equipment.

Unlike wood blocks, CADDY PYRAMID supports are specifically designed for rooftop applications, incorporating unique materials and finishes that protect roof membranes and provide superior corrosion protection.


  • Captive stainless steel nuts allow for custom attachment methods to the support base including easy attachment of stainless steel strut, threaded rod or other project-specific hardware
  • Foam bottom offers low abrasion interface for better roof membrane protection
  • Compatible with roof surfaces including single ply, bituminous, metal and spray foam
  • Provides superior load distribution, even with varying rooftop surfaces
  • Multiple sizes and load ratings offer the ability to tailor the solution to the application
  • Base is manufactured from UV-stabilized thermoplastic material
  • Supports green building requirements; thermoplastic bases are made from recycled material and can contribute to earning LEED credits
