Medium Electrical Box Frame

A single disconnect or control panel doesn't warrant a full equipment platform, so it usually ends up strapped to a curb or a screen post at whatever height was convenient. The Medium Electrical Box Frame carries it on two posts set on U-Anchor® bases, clear of the roof and at a height a technician can work at. The U-Anchor® is a component of the roof, not something sitting on top of it.

How it works

It starts with a U-Anchor®, a component of the roof, sealed watertight at the point of attachment. Everything else connects your equipment to that one point.

The anchor

The part that carries the load. A galvanized steel plate with rolled edges that protect the membrane sits under a cover membrane matched to the roofing brand, type, and color, leaving a stainless stud at the surface for everything else to bolt to. Which one you use is decided by the membrane on the building, not by the equipment.

The hardware

What connects your equipment to that stud. Supplied with the solution, and sold on its own where a job needs more of them.

The fittings

Strut column, Electrical or control box (by others), 3-hole corner gusset plate — fitted to the equipment itself rather than to the roof.

Why it works

WATERTIGHT
Each post sets on a U-Anchor® base with a Compression-Free™ seal, so the roof assembly and its warranty stay intact. The box sits clear of the membrane, so there's nothing trapping water underneath and nothing to work around at re-roof.
ENGINEERED
Sized for medium boxes, panels, and disconnects, with enough structure to hold the gear steady in service and without the footprint of a full equipment platform. Where the load is bigger, the Large Electrical Box Frame carries it.
PROVEN
Installed on commercial roofs nationwide, across every common membrane. The same attachment method carrying pipe and equipment on those roofs carries the gear.
