I just want to add something to the description on the type listed by quikduk as 2. These are what I have on the drawers under the closet on our 2004 Fleetwood Flair 33R. The "black tab" is in the track and they look like you should be able to push in on the tab, but what you need to do is pull the drawer out to its full extent and there will be a little black lever inside the track sticking out beyond the glider, but inside the track - just a little black stick. On one side you pull upwards on that lever and on the other you push downward and pull the drawer outward and it will come out. The little black tab on the end of the glider is the stop and the lever inside the track hooks on it unless you push or pull it. I think the action is opposite the action of the tab (I just did it, but I can't remember which was which.) Without quikduk's help, I probably would still be trying to open that thing @%#! Thanks, quikduk!
