Custom Deck Bench and Railing - Kreg Owners'… I don't have a deck, but if I did, I would love to have deck benches and railings. ... They have a 13 degree recline, 17" seating height, and 36" railing height. ... I haven't built them, were you going to build them with 2x4 or 2x6 stock? ... I'm thinking about doing a variation of this in 2x6 for a pre-existing deck.
