Secure Hinged Frame to Deck

What happens here

With the hinges attached to one side of the wooden frame, carefully position the entire frame assembly alongside the hot tub on the deck. Use a spirit level to ensure the wooden frame is perfectly level and aligned with the hot tub and the surrounding deck surface. Mark the locations for the remaining screw holes of the hinges on the deck, and then use the cordless impact driver to securely fasten the hinges to the deck. This allows the frame to pivot open and close smoothly, as demonstrated when the builder lifts the frame to check its action.

Goal: Affix the hinged wooden frame to the deck next to the hot tub
