Install Stud in Cushion:
PARTS LIST:
Bolts, 5/16 -18 x 2 1/4" (H5531) - 2 qty T-nuts (H1992) - 2 qty
Washers, 1/4" ID (H283) - 2 qty
- Remove the staples securing the vinyl cover to the bottom of the cushion.
- The foam has been glued to the plywood. Carefully separate the foam from the plywood enough to access the T-nut that the cushion was originally mounted with.
- Push the T-nut out of its hole and remove it. Insert the end of the enclosed bolt through a washer and into the same hole from the foamed surface.
- IMPORTANT - Add a generous amount of RED (permanent) thread locker, such as Loctite brand, to about a 3/4" area of threads starting at the head of the bolt. "Generous" means not just a drop or two.
- Push the bolt through the wood until the washer is against the wood resulting in the rest of the bolt protruding from the bottom side of the cushion.
- Thread the T-nut on the bolt with the barbs pointed towards the wood and then spin it on until the barbs are at the surface of the wood but don't score it.
- Lock the chuck of a cordless drill onto the threads of the bolt and set the drill on its Reverse setting. Push the bolt and T-nut down so that the barbs of the T-nut sink into the wood. Power the drill to turn the bolt until the washer on the top surface begins to be drawn into the wood.

Staple the vinyl cover on the cushion.
