Mounting an HVAC unit with metal roof brackets to your roof can pose lots of challenges; lining up screw holes on heavy units, adjusting levels, making sure all penetrations are weatherproof and so on.
The GRipperFix and S-5 clamp system makes it all so easy. Simply identify the appropriate roofing profile here.
If you need to direct fix the GRipperFix rails to the roof then you can bypass this step.
Position and attach the downslope clamps first then the upper clamps. The sliding tabs make attaching the GRipperFix rails very simple whether you’re using S-5 clamps or direct fixing.
You can add vibration reduction and levelling pads to raise the lower strut on sloping roofs to ensure the HVAC unit is level. Once everything is nicely lined up final tightening of the screws will ensure your HVAC unit stays where it’s meant to be.
