I used an Arlig door as a cover panel for the 30" cab used as a blind cab. I bought a 15" but changed my mind and cut it to 12"W before installing it. If someday I want to add a door, an 18"W door should fit.
These are notes from kingdave@mac.com's install I saved for future reference.
I installed my Numerar Aluminum effect countertops and butt jointed the finished edges togther as you did, without the double stick tape. Here's how I finished the job:
This pantry has been mostly empty for almost a year so it’s not like I have to hurry and get it done so we have running water again. I would like to finish by Christmas though.
First, all the suspension rail up and the first cabinet up:
T - No, no extra key. 1 5/8" screws work fine - the leg block is 1" thick, plus the 3/4" for the cabinet, and even allowing a bit for compression of the block when the screw is driven, and there's no problem at all.
