HANDYGO Swing Set Brackets - Heavy Duty Steel Swing Kit, 2 DIY Wooden Swing Hardware Bracket, Playground Equipment Parts, with Mounting Accessories, for Outdoor Play, Green

We used these to put together a frame for a large size porch swing. They worked perfectly.

Luv my new swing set!

Bracket was perfect, had to shave the 4x6 wood as others mentioned. (Very) Annoying but manageable. The lag bolts are inadequate for hot/ humid weather. Purchased stainless and galvanized (stainless for swings to attach to swivels and galvanized for the bracket here) plus new washers. Brackets themselves are excellent quality. The 4x4 “legs” fit just fine. Used hammer drill with socket attachment.

Easy to install and very strong
