Gather your drawer sizes
At this point it's a good idea to grab a piece of paper and create a table to record the details of your IKEA MAXIMERA drawers. Let's walk through an example with a fictional kitchen (that i wouldn't recommend building!)
Drawers 2, 6, 8 and 10 are 'bottom drawers'
All other drawers are defined as 'upper drawers'
Garbage sorting drawers are considered 'bottom drawers'
Note that for the example there are also three internal drawers in the 2nd, 3rd & 4th cabinets from the left. We do not list these in our table since internal drawers are not converted to push-to-open.
Columns A - F should be pretty straightforward to complete from your plan or just measuring your current kitchen.
Column G is an approximation of the Synchronization rod size you'll need for that drawer. Just subtract 25cm from the width of the cabinet that the drawer sits in. Column H will be explained shortly.
Make a note of the number of bottom drawers and upper drawers.
