I've used full extension slides for years . in the kitchen remodel in Delaware, In the workshop for storage space under the work bench. Now in Virginia and the cabinets installed by the mfg are really lacking in storage space. So after a few years making all of the under cabinet space full of full extension drawers so you can get to what would have been shoved into the back of the cabinets. The cabinet space even stated as 24 Inch are really about 23 and so a 22 inch deep drawer are great. My biggest problem in making drawers are the slide thickness is 1/2\" and two sides are 1 inch space lost, then there is the thickness of the drawers. I'm using 1/2\" ply so 2 inches of the opening are gone with the slides and the wood thickness. BUT the useable space is almost double what was there from the MFG. Just make sure that the drawer is no too close to the usable space between the installed slides. I give 1/16\" to 1/8\" so that the hardware slides without having to close the drawer. The slides that i bought were fantastic and very reasonable.
