Boat Dock Jack | Boat Lift Jack | The Revolution

The Dock Jack is the featured product of JackDocks.com! This product makes adjusting your dock or lift as simple as the zip of a cordless drill. Dock Jacks are aluminum dock supports with a screw gear mechanism, allowing you to change the height of your dock or lift while standing on the top of the decking. No more getting in the water with your tools. No more heavy lifting. This is the preferred dock leg of any dock owner. Mount it to your dock or lift with wheels or with a drop leg, and voila, you have a dock system without the headaches of adjusting. Check out our size options and different adapters to make the jack roll or stationary.
