Building a sturdy wood shooting platform is fairly easy, but elevating and stabilizing it in a way that creates a structure capable of lasting through seasons of changing weather is the hard part. That's where these Elevators come in. Built of heavy-duty steel, they'll help you easily construct the corner joint sections of your platform - the areas most vital to structural integrity. Use all four to easily build a free-standing platform or blind. You supply the pressure-treated 4" x 4" posts and lumber for cross bracing (not included). 4 Pack.
