The overall measurments of my rack is:
33 1/2" Deep x 17" wide x 60" tall.
As you can see from the pic. my racks are only 7 boxes tall, so they can be built taller to accomidate more boxes per rack. I just perfer not to have to deal with boxes above eye level.
I use a 4' x 8' sheet of peg board for the tops. This gives great ventalation in my opinion. I am able to get and cut 5 pieces ( measured at 33 1/2" x 17" ) from one 4' x 8' sheet.
I then make a frame from 2x2's the same dementions
( 33 1/2" x 17" ) and screw the peg board to the frame making sure the smooth side will be out ( meaning, screw the frame to the rough side of the peg board ), using drywall screws.
Once I have all of the tops put together, I cut the 4 legs. These are 60" tall.
( but they can be made as tall as you would like )
These are made from 1" x 3" boards.
To attach the tops to the 4 legs I lay one top upside down on a flat surface, stand each leg against the frame on the oustide corners of the longest side and screw them on. Then I screw on the bottom braces to the other end of the legs.
I actually put this rack together upside down.
I then use a spacer ( which is 5/8 in. ) placed on the first top, then put the slide rail on top of the spacer and screw the slide rail on. Once the slide rail is screwed on, I just remove the spacer. This gives you the space neede for the box to slide in. It also gives you a 1/8 in. space between the top of the box and the top on the rack.
After that step, I take another spacer ( which is 6 in. ) and set it on top of the slide rail. Then I put in another top and screw it to the legs. This spacer gives you the distance you want between the boxes, so it can be made to what ever measurement you want your boxes apart for each other.
That's about it. I just keep building them up, alternating spacers for the slide rails and the tops until I've reached the amount of boxes I want per rack. Then just turn it over and it's done.
These measurments are for the Iris CB70 boxes ONLY !!!
A rack can be biult like this for just about any size box, you just have to figure out the measurement need for the box you are using. The actual assembly can be done basically the same.
I hope this helps you and you understand the procedure. I know it's a little odd that I assemble these up side down, but when you put one together you will see it's way easy doing it like this.
Later and good luck,
