1/2" Carriage Bolts and Wood on Wood
Don’t rely on flimsy powder coated metal plates to mount the swings to the fort. MY design utilizes wooden 4” x 4” blocks and ½” bolt thru beam carriage bolts and 3/8" lag screws to secure swing beam to fort. When you see this, you will not doubt the strength of this all wood swingset assembly. This design also allows some flexibility to adjust for sloped yards, backyards that are not completely level or height requirements.
