Our makeshift supports for objects otherwise too high are okay… but what would be even better is ‘add on’ purchase option. Crumb trays of varying heights.
1 1/2 inch.
Caveat the minimum/maximum height at purchase time and again on installation instructions in the box.
I’d easily purchase several additional crumb trays for $50-$100 each. I’d likely purchase a single additional crumb tray if I had repeating need for $200. I’d probably need to be a business rather than a hobbyist to purchase a single crumb tray for more than $250.
