adjacent cabinet sidewalls 32 and 34 as shown in fig1 and 2 an inverted leveling device of the present invention may be used at the top of the cabinets to both retain them in position with the required spacing and to provide a guide hole for allen wrench 30 it may be preferable to have the receiving channels 18 a and 18 b of slightly different dimensions in that regard as shown in fig2 receiving channel 18 a is slightly wider than receiving channel 18 b in addition receiving channel 18 b has inwardly extending projections such as u201c dimples u201d 36 to provide a strong friction fit to sidewall 34 of cabinet 14 by using a second leveling device 16 at the top edge of adjacent cabinets the friction fit is on the adjacent sidewall 32 of cabinet 14 and thus both cabinets are rigidly secured together through the use of dual leveling devices 16 device 16 may have inwardly extending projections such as dimples 36 in both channels 18 a and 18 b with reference to fig3 there is shown an alternative embodiment of the present invention wherein threaded member 24 does not include a foot pad 26 but rather the device includes a separate component in the form of a base plate 38 which has indentations 40 for registering and receiving the distal end of threaded member 24 in an alternative embodiment fig4 shows a leveling device 16 in all respects the same as that shown in fig2 but also including a base wall 42 that partially encloses cavity 44 base wall 42 also includes threaded opening 46 for receiving threaded member 24 therethrough while the.
