    Alright so I'm making this double pocket door unit, both doors are opened in sync with traveler -esque rigging. the unit lives behind a cut drop so it looks like the doors are part of the drop, make sense? have a look at the photo, its the purple thing. The doors have little tabs that stick up and get pinned into this thing I can't name. would you call it a dog? its kind of like a master carrier. It gets pinned in because this unit breaks into 3 pieces for storage. Doors don't hang from a track, but are mounted to the side units with drawer slides.

    edit: and yes, I used the snipping tool to take the screen grabs, not sure why its there in bold letters haha

    I've always just called it a carrier.

    Since it's connected to an operating cord, I would call it a "Dog", or a "Rabbit". Very similar to the 'slave' master carrier on a traditional Traverse rod style curtain track where the rope is locked to the carrier as opposed to the Master carrier where both ends of the rope are dead-ended.

    I'm with Van - I'd call it a dog - or dawg - but I'm not sure that is correct - as the term dog as used in machinery seems to imply teeth and gripping. I guess this grips the operating line.

    If you pick a track, I think it will be obvious in the track parts available for that. The operating line is usually below the track and above the piece. I can't tell where you carriers are.

    I would call that part that sticks up out of the door a dog and the thing it pins into the carrier (or master carrier if there are idler carriers not pictured holding the door up).

    no carriers on this one. the only mechanical attachment between door and header piece is the tab. all weight of the door is born by drawer slides in the side units, allowing the whole thing to break into 3 pieces by only pulling a 2 pins and 4 coffin locks. Weird way to do something like this, but we've got to meet client specs. you know how it goes. Everyone in the shop is dubious about this, I'll see if I can get a video of it when it works...

    So where are the drawer slides? Single track At the top? I am just wondering what kind of alignment adjustments you will have to get this all square, and closing true.

    Ok. So three "boxes" for travel - 2 side pockets with the doors mounted on full extension drawer slides and a top box that has traverse operating hardware and kind of holds it all together. Whatever comes off top/back of door to attach to operating line doesn't need a name. It's a tab of sorts. Looks like quick disconnect but wouldn't it be better for transport if that tab didn't project? Maybe you've got that covered. I feel like with drawer slides attachment should be as offstage as possible, exerting minimum forces on unsupported door edge but trivial.

    Looks good.

    Looks awesome! Care to share any changes you made to the original sketch and the bill of materials you used?

    No changes, only thing we had to tweak was drawer slide placement. In the video you can see a gap at the bottom of the doors where they meet. All it took was 20 minutes of shimming/jigging/swearing and the gap closed up... I'm not going on this ship to install but I'll see if I can get a video of it in place with the drop.

    Well this is as close to the finished product I'll get. Added velcro and made sure the cut in the printed drop matched up to our doors.
