I built this commercial label printer cabinet for a friend. Each shelf (which is on drawer slides) will hold a commercial label printer that prints 4”x6” labels on a roll. As the labels spit out of the printers, they need to fold over accordian-style onto a mini-shelf in front of each printer. When the stack of labels are done printing, the mini shelf is popped off and taken over to the packaging area.

My thought was to use french cleats for the shelf-drawer handles (so the operator can pull out the shelf-drawer to change the label roll in the printer). But the leverage of the mini shelf is too much and they just don’t stay on the handles at all.

The requirement is that the mini shelf is quickly and easily removable. It’s in a fast production environment so using latches or something that requires an additional step to attach the mini shelf is not going to work. It needs to be put on the front of the shelf-drawer quickly and easily, and removed quickly and easily. No latching, no pinning, no hooking.

Any suggestions?

My first idea was to drill out a couple of 3/8” holes vertically in the mini-shelf cleat and glue in a 3/8” x 3” dowel in hole. Then drll out a slightly larger 7/16” hole vertically in the shelf-drawer handle cleat and bore out the top of it a bit, to receive the dowels.

edit: My friend (the customer) suggested using rare earth magnets to hold the mini shelf cleat to the shelf drawer cleat. With that much leverage on the mini shelf, I just don’t think magents would hold. And if they did hold, they would be so strong that “quickly and easily” removing the mini shelf would be a struggle, I think. Yes?

I like the French cleats or buy those plastic bins.

Instead of the 45 deg french cleat, try a half lap type of joint. Maybe use 1” thick material to add some strength.

Excellent and simple solution jbay. I feel like a bonehead for trying to over-engineer this. Thanks for the picture, made it really simple to understand. I think I just learned something—french cleats aren’t the answer for everything.

Or…..

If you put the half-laps on the sides, you can double the bearing surface for even greater stability. A slight bevel on bottom of the hanging cleat will help with insertion.

Finished product installed at my friends warehouse. Thanks for the half-lap idea for the removable label trays. I re-made the trays out of 1/2” ply and 1/4” for the floor to try and lighten it some more.

Oooo. I like this. I didn’t see this post. But if my horizontal half-laps break, then I’m going with this idea! I’ll probably shorten those side half-laps so that the label tray top sits flush with the shelf when it’s inserted.

Have your say...
