Hi Jay. I have done this two ways -
One is to just drill four 1/4" holes thru convenient adjacent
hardware
and bolt the cabs together.
That's basically what DEC did. I'm not sure if my cabinets are the
same type as Jay's; they're original DEC, black frames with grey side
panels and melamine (on steel) grey tops. Dimensions are 49_1/2" high,
20_1/2" wide, 28_1/4" deep.
The side panels are grey sheet steel with stiffeners on the inside (and
surprisingly heavy); at the bottom, they hook over the horizontal side
member of the rack, and at the top they have two steel "buttons" which
engage teardrop-shaped holes in the top horizontal side member.
The joining kit consists of 4 (or maybe 6, but I only have 4) bolts
with nuts and star washers, and a couple of black-painted alloy
extrusions which fill the small gap between the racks. The spacers
aren't essential, but you might want to put 1/8" worth of washers in
their place if you don't have them.
On the top horizontal side member, at front and back, are two holes,
2_1/2" and 3_1/4" down from the top of the cabinet. A bolt passes
through the lower of these at front and back, through the spacers,
through the corresponding hole in the other rack, and is secured with
star washer and nut. Ditto on the bottom horizontal side member,
except the holes are about 1/2" and 2_1/2" down from the top of the
side member, and it doesn't matter which hole you use, as the spacer
has two matching holes.
This is an attempt at an ASCII art diagram of the cross-section of the
extrusion:
_______
|___ ___| front, 3/8" wide
| |
| |
| |
| | distance between front
| | and centre "wings" is 1_1/4"
| |
____| |____
|_____ _____| centre, 1" wide
| |
| |
| | distance from centre "wings"
| | to back edge is 7/8"
|_|
All sections 1/8" thick
And this is a diagram of the side view of the front extrusion, showing
the positions of the three holes:
|\
||\
___|| \
| o|| ||
| || ||
| || ||
| || ||
| || ||
| || ||
| || ||
| || ||
| || ||
| || ||
| o|| ||
|_o||_||
The back extrusion is just the same, except without the cutout or bevel
at the top.
Does this help?
