3rd Hand Support System is a material handling tool from Fastcap that is designed to make hanging upper wall cabinets easier when base cabinets are not in place, so cabinets can be positioned without relying on lower support. The Upper Hand jack system functions as a temporary support under the cabinet, which simplifies holding, leveling, and fastening during installation in shops or job sites. A single jack can support up to 150 lb., allowing one point of support for substantial cabinet loads in typical woodworking applications. The jack extends from 28 inches in the fully closed position to 60 inches in the fully opened position, so it spans a wide range of working heights between floor and wall cabinet bottom rails. This adjustable range lets installers work in rooms with different ceiling heights while keeping the cabinet in a workable position for fastening.
The jack extends from 28 inches in the fully closed position to 60 inches in the fully opened position, so installers can dial in working height between low and high cabinet mounting scenarios without changing tools. An ergonomic pump handle adjusts the jack in 1 inch increments, giving controlled step-by-step movement that helps bring cabinet bottoms exactly to layout lines before fixing them to the wall. The top and bottom feet are 6 inches by 6 inches and in fixed position, so the support head and base stay aligned as height changes, keeping load transfer predictable across the full extension range.
The Upper Hand jack system is designed to make hanging upper wall cabinets easier when base cabinets are not in place, so it serves as a temporary vertical support in kitchens, shops, or other wall storage projects before casework below is installed. In material handling tasks, the extension from 28 inches to 60 inches allows the same jack to work across different cabinet mounting heights commonly found in woodworking layouts. The broad 6 inch by 6 inch top and bottom feet create stable bearing surfaces against floors and cabinet bottoms or rails, which helps keep cabinets steady as fasteners are driven. A single jack can support up to 150 lb., so it can hold individual cabinets or shorter runs during positioning in a typical installation workflow.
An ergonomic pump handle adjusts the jack in 1 inch increments, translating hand strokes directly into predictable height changes, which simplifies hitting repeated measurement marks along a run of wall cabinets. Because the extension range is 28 inches to 60 inches, installers can set up the support at a known starting height and then use the 1 inch increments to match layout lines on multiple cabinets in sequence. The fixed 6 inch by 6 inch feet keep the load path centered throughout these adjustments, so the cabinet remains supported in a consistent orientation while fine tuning gaps and reveals. With a single jack supporting up to 150 lb., the installer can hold the cabinet at the chosen increment while fastening, which supports repeatable results from one cabinet to the next.
