I added a cross pole to my recently purchased Z Packs Duplex Tarp. I just threw the parts together to make sure it works but the final version should be pretty close to an ounce in weight. No backpacking experience with it yet but I’ve used a similar rig on my one person tent (shown in avatar) so I’m pretty sure it will work out.

Advantages of cross pole are small but appeal to me.
(1) It allows me to get the tarp set up with only 4 stakes so I can quickly jump in out of the rain. I can worry about staking the vestibules and end pull-outs later if the rain stops or just ignore them if I can live without them.

(2 There isn’t much stress on the cross pole. It is there primarily to keep the hiking poles apart. This set-up feels more secure and less strained (to me) than the staked out guy line set-up that is typically used. It also seems like there would be less chance of the guy lines ripping out where they are attached to the tent peaks. Some engineer here will probably prove me wrong. My analysis is based upon “feel”.

(3) Vestibules could be secured directly to the poles, thereby eliminating the need for the two vestibule stakes.

I have the Duplex, I really enjoy it. In a strong cross wind you'll still need the vestibule guy lines, otherwise I don't see how the cross member connections have enough strenth to hold the poles in a verticle position.

For mods, I've done the following:

1)Install 3/8" fishing split rings on the beak tie down loops. It's much easier to hook the split rings to the carabiner, especially in the middle of the night.

2) Extend the guy lines 36" with microlocks. Allows me to easily attach to rocks, wood or move the stakes in or out to a location where I can drive the stake in.

3) Install a cord(1.25 mm Z-Line) inside, near the top, between the poles with loops every 6 inches. Works like a clothes line to hang items from.

4)Working Mod: Add a short piece of carbon rod between the beak sheets near the top to keep the beak sheets seperated about 2" apart. In cold weather I've had condensation, so I'm hoping the gap will allow better air movement.

Kenneth,
Really like your mods.

1. Did you specifically buy 4 3/8" fishing split rings vs standard office supply split rings b/c the fishing split rings are stainless (or something similar?), whereas office ones would eventually rust?

2. I haven't extended 3', but I have added microlocks. Just makes getting a tight pitch much easier, and there is an 80% chance that I won't be able to insert a stake at the exact length that zpacks cut the line due to a rock, or big root or whatever…just being able to move a couple inches makes a big difference.

3. Excellent idea….and zpacks was kind enough to already sew on loops on the inside to attach the line.

I bought the fishing rings as they were easier to obtain in the smaller sizes. Stainless steel was an added bonus.

Daryl,

Am I crazy or is the Duplex freakishly close to your homemade/BPW custom tent? Take out the differences in the side beak areas and they look like twins from afar.

Christopher,

"Am I crazy"

"is the Duplex freakishly close to your homemade/BPW custom tent?"

Answer to the 2nd question is "yes".

I've been a fan of dual side entry 2 person tents with an inverted-U shaped pole for over 40 years. Here's a photo of my first one which I made in the early 1970s. It weighed 3.9 lbs.
