350mm Back to Back Roof Support System

This Back to Back Roof Support System is part of the Unifoot range and is specifically designed to hold 82mm back-to-back strut or 2 x 41mm Unistrut-type channels. It provides a stable and non-penetrative solution for mounting ductwork, pipework, and cable containment systems across flat roof surfaces.

Each unit features a 350mm x 350mm footprint with a 95mm height, manufactured from 100% recycled SBR rubber. The base offers both anti-slip and anti-vibration performance, which helps to reduce structural stress and noise during operation. Because no drilling or adhesives are required, the unit can be installed in minutes while protecting the roof membrane.

Compatible with all standard Unistrut 82mm back-to-back channels or dual 41mm channels, this system is ideal for creating wide-set support platforms with enhanced load distribution. Its modular design allows you to use multiple units in parallel, enabling support of grouped services or larger frameworks.

The Back to Back Roof Support System supports up to 200kg and weighs 5.5kg, making it easy to carry and position on site. Whether you are working on an HVAC install or managing rooftop containment layouts, this foot offers strength and flexibility without compromising roof integrity.
