Counters and worktables (desks, workshop counters) are supported in to basic forms; open and enclosed.

An open counter simply surface-mounts by T-nut attachment to wall and floor profiles but is otherwise open relative to the wall volume. Modest scale ones are supported on walls alone, using a series of diagonal profile braces that attach to the front of the Secondary framing, just like the simple shelving described elsewhere. Heavier/wider counters are supported on ‘L’ shaped profile frames in line with the floor grid. The support frame can then be ‘boxed in’ with simple paneling attached to those profiles with the usual T-nuts or slot snap-in strips and can also be framed as shelving or small under-counter cabinets. This form of counter is likely to be used in combination with surface-mount overhead cabinets and shelving and is well suited to simple kitchens and quick-built desks and worktables.

An enclosed counter is usually integrated with a supercabinet complex, as previously described, where a unit room space (usually about a meter deep as per the standard floor grid) is framed-up with Secondary frame members to form a complex of shelves and cabinets running floor-to-ceiling. Here a counter is installed in the same way as a shelving plank supported from the sides and with the aid of additional reinforcing profiles but potentially with a large overhang and protruding some distance from the flush surface of the cabinet/wall. Back panels finish the surrounded volume of the counter and can include their own shelves. Hinged countertops are also possible, allowing for a fold-out workstation integrated into the larger supercabinet. A very good approach desks and infrequently used workstations.
