Multi Frame, featuring selection tool

HOUSTON--RectorSeal® LLC, a manufacturer and distributor of quality HVAC/R products, introduces the Multi Frame, a five-SKU packaged approach that simplifies designing, inventorying and assembling Big Foot® Systems’ modular, tubular steel framing mounts for VRF/VRV condensers in U.S. and Canada. The introduction also includes Frame Tech, Big Foot Systems’ new online program that eliminates the guesswork in rooftop equipment support configuration and engineering.

Multi Frame consolidates Big Foot’s previous standard product line from 80+ SKUs to five pre-packaged kits that are ordered through wholesale HVAC distributors. The standard rectangular Multi Frame kit consists of two 40-inch-long (102-cm) end bars, two 48-inch-long (122-cm) cross bars, four leg assemblies with 12-inch-square (30-cm) nylon feet, and two 2-clamp kits for securing the condenser to the frame. Each 40 x 48-inch frame has a 1,200-pound (544-kilograms) total weight capacity that accommodates any VRF/VRV brand and model.

The system accommodates one or two condensers, but is scalable to an infinite number of integrated frames and configurations with the Multi Frame extension kit and the other three supplementary SKUs. Any Multi Frame project can be widened, deepened or lengthened into any conceivable geometrical configuration with an extension kit, which consists of two end bars, two cross bars, two leg assemblies, two tubular steel connectors and one clamp kit.
While the previous Big Foot Systems product line gravitated toward highly-engineered jobs requiring consulting engineer specification, parts selection, Big Foot factory engineering and other tasks, Multi Frame’s five packaged SKUs reduce ordering/shipping time from weeks to just days.

The design-to-assembly process is expedited with Frame Tech, the online tool that leads HVAC wholesalers through user-friendly prompts to design and specify layouts for engineers and contractors. Frame Tech designs and prints out complete specifications including wind load ratings, SKU list for each condenser, configuration diagrams and assembly instructions. Frame Tech accommodates the largest rooftop configurations down to just a Fast Fix stand for a ground-mounted mini-split condenser. The print out is invaluable for consulting engineering verification, building inspectors and onsite assemblers.
The main Multi Frame system can accommodate pitched roofs by adjusting the frame up or down the threaded 12 to 18-inch (30 to 45-cm) legs. Tall legs of 18 to 24-inches (45 to 61-cm) are available for roof pitches or to surpass snow drift codes.

Besides the basic Multi Frame and the extension kit, the other three SKUs are: 1) Multi Frame tall with 18 to 24-inch legs; 2) Multi Frame tall with 18 to 24-inch legs extension kit; and 3) an extra 48-inch cross bar kit (auto-populated during Frame Tech designs) for VRF/VRV brands that require six total mounting rail touchpoints of condenser support.

Other Multi Frame advantages are:
• Price is less than the cost of fabricating labor for an I-beam or lumber mount;
• Also applicable for ground mounting;
• Can be mixed and matched with VRF/VRV and ductless mini-splits, as long as the latter is accommodated with enough venting space;
• Can also be used for other HVAC rooftop equipment.
Big Foot Systems is the only corrosion-resistant, hot-dipped galvanized steel equipment mounting frame that outlasts other steel frame brands and reduces labor versus general construction material gerri rigging. Re-roofing is possible without disassembling HVAC equipment, because roof sections can be replaced under one removed leg at a time.
