I want to extend the back of the box past the guides to fit two trash bins. What is the trick for getting the box to set into the pins on the back of the guide and still run past?

How much do you need to extend it? Could you move the slides back so the pin goes into the back and then add 1/2" maple cleat for the locking devices to attach to?

If there's enough cabinet depth, why not try a longer slide? Barring that, I would say try mounting a sub-platform to the slides (see Blum's instructions for roll-out shelves), and attach your trash unit to the platform. Build in some kind of adjustment (oversized holes, etc.) to fine-tune alignment of the trash pull-out in relation to the platform/shelf. In the second scenario, keep in mind that you won't get true full extension of the unit.

Or just buy one from Rev-a-shelf :)

Run a 3/4" bottom or a 1/2" bottom with a 1/4" skin over top(the holes will be in the ply bottom) and extend your drawer sides and back as as far as you want. 3/4" bottom would just need a large rabbet along the back. Agreed with other posts of either buying or longer slides but assume there must be some extenuating factors. I think we pay like $110 bucks for a double trash roll out from Rev-a-Shelf but we do often make our own because customers want to pack a bunch of other stuff in all that wasted space. My input is to talk them out of having stinky trash inside your cabinets in the first place lol.

I did that before and it turned into a really bad idea - because the pullout wasn't a true full extension, the rear trash bin couldn't be put in or taken out once the countertop was installed above. Make sure you are considering that.

Thanks. I think I only need another two inches, and 24" blums wont fit inside the cabinet. So I think I will go with a cleat for the front clips that is moved rearward. Then leave enough slop to remove the rear can.

Use the bottom mount Movento slides. They have over travel, and a higher weight rating.

I have spent my life making those because I knew I could build a better one, just not less expensive. I have given up, buy the thing and move on. They come with two cans in the first place, are full extension with soft close. Four screws mounting to the bottom cabinet deck and four in the door front.

I make most of my trash inserts with Blum tandem and 21” glides. Why don’t two fit in ?

I get two into any box that fits into a 18” cabinet or wider. They are 35 qt however with a partition and drawer above . Not sure on the 50 qt. Perhaps that’s the issue ?
