All Grasshopper products can be assembled and installed by our customers.
Premium: Our Bolt-In version bolts into concrete slab and does not require additional support from a structural wall. Our FreeStanding, is actually freestanding, and requires no bolting into any infrastructure. -We recommend a Grasshopper representative be onsite for Premium installs (extra charge).
Hanging: Requires an inspection of your infrastructure to determine whether it can withstand the loading requirements. Once the the requirements are met, installation can be handled by customer.
We can send your contractor or you a specs list to determine if your building can support a hanging Master wall. Generally, you need a bearing wall with a header or a concrete structure to mount the pulleys to.
You need 13.5 feet height to get the wall to 20 degrees. But if you don't mind it steeper, 12 feet gets you to 30 degrees.
We recommend 13 x 13 feet of padding/landing space.
