The double-keyhole plate goes outside. The lower key operates the bolt. The upper key turns the latch if you have pushed the button or tripped the lever on the lock that disables the outside knob. If both knobs are disabled by the button/lever then you must have a small turn button/knob on the inside as well to serve the purpose of the upper key (outside) to operate the latch. This setup is tailor made to lock you out when you step out to get the paper or mail. Casey

You can make the doors just about whatever size you wish, yoiu may have to add additional hinges (3 vs 2) to support the additional weight. I would use a continuous piano hinge to join the two doors togather. I have done 42 x 42 corners with no problem and all dimentions in between. I often use odd corners 39 X 37 etc, in lieu of using fillers to center sinks etc. If you have additional space after you install a lasy susan, I have put tray dividers and used the small spaces for cookie sheets etc.

You might get more responses if you post this in the Kitchens forum. Also, I don't think "comparable" means what you think it means.

IKEA sales -- and the third party kitchen installer -- guaranteed that the Sektion legs would support a stone countertop. Still, I was not reassured. These are adjustable legs so the legs are not supporting the weight, the screw threads are supporting the weight, and the screw threads are plastic and only a few millimeters deep. A leg failure could cause a countertop crack, shift, or even a fall with the potential for significant injury or foundational damage. I opted to place a better-rated 2x4 (x 4 ¾) at each of the leg sites; they fit nicely between or in front of each adjoining cabinet. An 8-foot length of 2x4 is rated for 1000 lbs vertical weight load; each block should provide similar support. I employed 22 such woodblocks. I made sure that the fit was snug but also ensured that the adjacent leg(s) continued to be weight-bearing. Typically, cutting the woodblock within an eighth-inch allowed me to slide the block to such a snug site, somewhere under one of the cabinets. The final woodblocks required an exact fit and I had to plane the length to achieve a snug fit. See below, and also note the Sektion Leg threads.
