Tub floor

Overview

For most users, we recommend installing shock cord at each of the four upper tub corners, at the midpoints along each long side, and at the extensions at the head and foot. Clipping the upper corners out to your tarp's corners will allow the floor to hang. To help keep the tub more secure in the wind, some users may wish to install additional cord at the tub's lower corners. These cords then get clipped out to the tarp's stakes (alternate: stake the four lower corners directly to the ground).

Optional Rigging Kits

Rigging kits are available for connecting your floor to your tarp. Four options are offered.

• Options A & C include Tensionlocks. These install at the corners and make for easy adjustment of your cord lengths. They are most useful if you expect to pitch your tarp at varying widths.
• Options A & B contain less shockcord and are sized to work well with the 1P Cirriform Tarp.
• Options C & D contain more shockcord and are better suited for use with larger tarps.

1 - Determine cord lengths

For pitching with a 1P Cirriform, see our length recommendations in the diagram below. Otherwise, use this method:

1. Pitch your tarp (err on the wider & higher side) and lay the floor out about where you'd like it positioned.
2. Run some shock cord from a front corner to the associated corner of the tarp. The cord should be taut, but not stretched. Cut two cords at this length (one for each front corner).
3. Repeat for the rear corners.
4. Repeat for one of the midpoints.
5. For the extension at the head end, measure the distance from the head end of the floor (at ground level) to a hang loop above and subtract ~15" (38cm).
6. For the extension at the foot end, measure the distance from the foot end of the floor (at ground level) to a hang loop above and subtract ~10" (25cm).
7. After installing the rigging and pitching the floor, determine the length for the remaining midpoint by running the cord from the midpoint, through a hang loop above, and to the cord attached to the opposite side.

2 - Install the rigging at the corners (if not using tensioners)

1. Cut the shock cord to length (see above).
2. Tie a mitten hook to the end of each cord. We like to use a clinch knot.
3. Tie a loop in the other end of the cord. We like like to use an overhand loop knot.
4. Attach the cords to the tub's corners using a girth hitch (excluding the longer cord at one of the midpoints).

2 - Install the rigging at the corners (if using tensioners)

1. Cut the shock cord to length (see above).
2. Tie a mitten hook to the end of each cord. We like to use a clinch knot.
3. Using a girth hitch, install a tensioner on the elastic loop at each of the tub's upper corners (see photo sequence below).
4. Thread the untied end of the shockcord through the tensioner as shown (first through the middle opening from bottom to top, then through the remaining hole from top to bottom).
5. Tie a loop in the untied end of the cord. We like like to use an overhand loop knot.
6. Repeat at each corner

3 - Install the rigging at the head & foot extensions

1. Cut the shock cord to length (see above).
2. Tie a mitten hook to the end of each cord. We like to use a clinch knot.
3. Pass the untied end of the shockcord through the webbing loop.
4. Thread the untied end of the shockcord through a cordlock.
5. Tie a loop in the untied end of the cord. We like like to use an overhand loop knot.
6. Repeat at the other extension.

4 - Midpoints

1. Cut the shock cord to length (see above). You will have one short cord and one long cord.
2. Tie a mitten hook to the end of each cord. We like to use a clinch knot.
3. On the short cord, tie a loop and the other end, and install it at one of the midpoints as done in Step 2 (non-tensioner method).
4. Take the longer cord and pass the untied end between the webbing and the floor as shown in the photo (not through the top part of the loop).
5. Thread the cord through the cord lock, then tie a loop in the end.

Tips

• If you find that your cords are slack, or the tub's walls not pulled taut for your widest pitches, trim your cords (or tension them, if using tensioners).
• For narrower tarp pitches, take up slack in the cords using one of these methods:
  • Double over the cord by running it through the tarp's tie-out and then clipping it back to the tub.
  • Tie a loop along the length of your cord. Clip the mitten hook to the loop, then clip it to the tarp's tie-out (eg. to make a 30" cord have an effective length of 20", tie a loop 10" from the mitten hook).
• To raise the sides, cinch the cords attached to the midpoints using the cordlock.
• For additional stability in the wind, either stake the bottom corners to the ground, or run cords from the bottom corners to your tarp's stakes.
