Mounting Cat Mod Thunderdome

It’s important to read our basic mounting instructions before continuing on. The basic mounting instructions will help you determine what tools you will need and also about how to mount individual planks, sisal poles, Escape Hatches, and ladders.

This is a really fun layout. You will need six studs spaced out at 16″ from center to center. Start by marking the center of each of the six studs you’re using.

Since this is a rather tall structure and we’re going to be mounting pieces at multiple points of each stud, it’s nice to make a mark at several heights on each stud.

It’s easiest to cut your fabric before mounting the planks. Below are the different fabric cuts you will need to create The Cat Mod – Thunderdome.

When cutting the fabric to size, you want to cut 3/4″ out from the center of the grommets, on either edge. This length allows for the fabric to hold tight in each plank.

We suggest mounting the first step up the wall 14-20″ off of the ground. Attach the four-grommet-long piece of fabric and re-attach the plank top.

Take the Cat Mod Step and remove the top. Use a separated plank to clamp the last set of grommets down the fabric.

Hold the unmounted plank centered on the next stud over, at an upwards angle, with the fabric taut. You will want to be sure to mount the plank with fabric tight.

Trace the corner of the unmounted plank and mount it.

Each of the planks have three mounting holes on them. To mount the pole, mount the far left hole of each plank into the center of the stud. Another screw can be installed into the center hole, angled toward the center of your stud. Mounting the pole on the edge of your stud like this will ensure a taut top hammock.

Attach the seven-grommet-long piece of fabric to the bottom plank of the sisal pole and reattach the top of the plank with the furniture screws.

Attach a plank two grommets down the fabric, stretch it over to the left, and hold it centered on the next stud over, making sure the fabric is taut. Trace the corner of the unmounted plank.

This plank can now be mounted, using the two holes on the bracket that best mount into the stud.

Attach a separated plank onto the second set of grommets over and pull straight up. You will want to flip the plank, so that its top side is facing up, and mark the top right corner of the plank. Mount the plank and attach the fabric.

Attach the last set of grommets to an unmounted plank, stretch it over to the right, and hold it centered on the next stud over, making sure the fabric is taut. Trace the corner of the unmounted plank.

This plank can now be mounted, using the two holes on the bracket that best mount into the stud.

Mount a separated plank centered above the first plank mounted. The space between the two should be 21.5".

Attach the ten-grommet-long piece of fabric to the plank and use furniture screws to attach the wooden top to firmly hold fabric in place.

Use a separated plank to clamp the third set of grommets down the fabric.

Hold the unmounted plank centered on the next stud over, at an upwards angle, with the fabric taut. You will want to be sure to mount the plank with fabric tight.

Trace the corner of the unmounted plank and mount it.

Attach a plank two grommets down the fabric, stretch it over to the right, and hold it centered on the next stud over, making sure the fabric is taut. Trace the corner of the unmounted plank.

This plank can now be mounted, using the two holes on the bracket that best mount into the stud.

Attach a separated plank onto the second set of grommets over and pull straight down. You will want to flip the plank, so that its top side is facing up, and mark the top right corner of the plank. Mount the plank and attach the fabric.

Attach a plank in the last set of grommets down the fabric, stretch it over to the left, and hold it centered on the next stud over, making sure the fabric is taut. Trace the corner of the unmounted plank.

This plank can now be mounted, using the two holes on the bracket that best mount into the stud.

Next, mount a plank level to the top of the vertical sisal pole, but in the next stud over. Attach the last strip of fabric so that it’s coming off the right side of the plank and replace the plank top.

Use a separated plank to clamp the last set of grommets down the strip of fabric. Stretch the fabric to the right until the plank is centered on the next stud over, making sure the fabric is taut. Trace the corner of the plank and mount it.

Here is a link for mounting our Floating Sisal Posts. Here we'll just cover locations for them. Measure down 13" from each of the last two planks you mounted. Mount two of the Sisal Posts into the same two studs. Then measure down 11" from the left Sisal Post and mount the last one.
