I'm a super handy little gadget! If you're worried about getting a level decking area, you can use me to do the job in a flash.
I support the decking sub-frame, and I'm adjustable, allowing you to raise and lower your sub-frame as needed to create a level base for your deck. I'm available in a range of different sizes and I'm made from recycled materials.
