Frequently Asked Questions
Can you fabricate an adapter for any RTU?▼
Yes. By utilizing our 'Blueprint Fidelity' process, we can engineer a custom transition (curb adapter) that bridges the supply/return configuration of any new unit to any existing roof curb, regardless of age or manufacturer.
Do your roof rails come with wood nailers?▼
Yes. Our standard roof rails include pressure-treated wood nailers, allowing for easy attachment of roofing base flashing and counter-flashing, ensuring a watertight seal.
What gauge do you use for equipment supports?▼
Depending on the unit weight and structural span, we typically utilize 18 GA to 10 GA galvanized steel or heavy-duty structural channel to ensure zero deflection and long-term stability.
Do you offer seismic-rated hanging systems?▼
We supply a variety of hanging solutions, including Gripple® cable systems and structural trapeze hardware, that can be configured to meet specific seismic or high-vibration project requirements.
