I have taken apart our indoor basement climbing wall. It is lightly used. There are a bunch of full pieces as well as some cut and shaped boards. You can see the set up as it was in the pictures. Each plywood sheet is 3/4 inch thick and very stiff/durable and I have predrilled holes and added bolt inserts at regular intervals to allow for unlimited arrangements. Use mine to start and then add whatever you want to make it larger or customized.
Also included are about 75 climbing holds with bolts and screws as needed. I also have about a half bag left of the bolt washers with probably 150+ remaining.
If you want all the 2x4's to get you started on your own build you can have those as well, or leave them, whatever works.
The wall covered about 20.5x8 feet of wall space. The overhangs were additional on top of that. You can easily cut it down to customize it if desired.
Asking $550 OBO which is about 1/3 of the cost it took to build it all. Thanks for looking.
