Rohn Non-Penetrating Flat Roof Mounts (FRM)

The Rohn, FRM series mount models are a non-penetrating roof mount and also a ballast roof mount. We offer Rohn's 60" mast with a 1.25" outer diameter (OD) (FRM125) and their FRM 30" mast with a 1.50" outer diameter (OD) (FRM150).

The base of the ballast roof mount is 36" square with trays to fit 16" nominal concrete blocks. We also offer optional Rohn 1/4" thick Anti-Skid Roof Pad (FRMPAD1) to provide a protective barrier between the FRM mount's base and the roof.

The FRM roof mount is hot dip galvanized for corrosion protection and assembles together quickly.
