The “J-Wack” is a specially designed tool, used to install both the VinPost Repair and the VinPost Sentinel.
It hooks into the slots on the front of the VinPost. This takes the impact point from the top of the post, and repositions it to the side of the post at knee height, and away from the canopy and the trellising. This reduces the chance of injury and the damage to the trellising and vine.
The VinPosts are driven approximately 600mm into the ground, with the “J-Wack” using a standard jackhammer or Post Knocker.
The J-Wack is engineered from a single piece of ~30mm steel plate. The hook plate and anvil are the possible wear points. These are made from laser cut hardened steel. They are designed to be replaceable should they wear out. These are exclusively available from VinPost.
