Pumphouse flexi base frame ph-bf for either one single vrv/vrf or two "standard" twin fan condensers

The flexibility of the flexi frame means that "designing" is simple. The design consists of a flexi base-frame and a flexi extender-frame which combine to provide a solution for mounting any type of equipment.

Simply start with a flexi base-frame and add the required number of flexi extender-frame to create your own system. The flexi extender-frame can be added in a ny direction to make a system of any size in multiples of 1200mm. Each frame has a maximum dimension of 1200mm.

Each base frame ph-bf or extender frame ph-ef will support 500kg. However the installer must ensure that:

1. The load is stable and spread evenly across the frame.

2. The roof onto which the frame is being mounted can support the point loads of the frame and the equipment.

Length : 1200 mm
Width: 1200 mm
Min. Height: 300 mm
Max. Height: 405 mm
Max. Load: 500 kg
Weight: 30 kg


Everything you need comes in one box. Simply order a base frame (sf-bf) to support up to two condensing units; e.G. For six condensing units, order 1 x base frame (sf-bf) and 2 x extender frame (sf-ef).


Sure-foot is the quick and easy way to support roof-top air conditioning equipment, including split systems, vrv, vrf and other applied products. The feet have been designed specially to provide stability and spread loads evenly across flat roof surfaces. The galvanised steel frame raises a/c equipment up to 405mm above the flat roof level, permitting quick and easy access for roof maintenance.

For 2 x condensing unit or 1 x vrf/vrv unit order 1 x sure-foot base frame (sf-bf)


For 4 x condensing unit or 2 x vrf/vrv unit order 1 x sure-foot base frame (sf-bf) & 1 x sure-foot extender frame (sf-ef)


For 6 x condensing unit or 3 x vrf/vrv unit order 1 x sure-foot base frame (sf-bf) & 2 x sure-foot extender frame (sf-ef)

For 8 x condensing unit or 4 x vrf/vrv unit order 1 x sure-foot base frame (sf-bf) & 3 x sure-foot extender frame (sf-ef)


Continue to add 1 x sf-ef for every two condensing units or one vrf/vrv unit.

All metal components are galvanised steel for extra corrosion resistance.
Pre-assembled leg components offer huge savings on installation time.

Anti-slip, membrane-protecting, isolation mats supplied pre-fitted to feet.
Universal beam positioning provides flexible fixing options.
Standard strut components allow installer to customise designs.
Air conditioning equipment mounts by simple, standard, strut zebedee (not supplied).
Packaged for easier storage, transportation and identification.


The beauty of sure-foot is its simplicity and speed. Start with a base frame - 4 feet and a 1200 x1200mm frame - to support two split condensing units or a vrfnrv unit. Then add an extender frame for every additional two split units or one vrfnrv unit. That's it! Just two products, two part codes. So simple.

However, the installer must satisfy themselves that:
A) the load is stable and spread evenly across the frame.
B) the roof onto which the frame is being mounted can support the point loads of the frame and the equipment through the 380mm diameter feet.
