Review on Green Hanging Snap Hooks: BETOOLL Heavy Duty Swing Hangers For Wooden Sets, Playgrounds, Porches, Indoors, And Outdoors - 2400 Lb Capacity (2Pcs) by Joshua Talbot

I have these mounted with 4.5 inch Lags and they work great so far. I drilled 3/8 holes so the lags would fit super tight and then coated the lags with heavy duty exterior glue in the hopes they wouldn't back out ever. We've only had the swing up for a few weeks but so far so good.One slight problem though - if you plan to do these with a socket the bolt running through the unit is a bit long and you won't be able to get your socket around both at the same time. I had to do one side halfway, loosen this bolt and then do the other side halfway, and then complete the cycle to get both tightened firmly. If you are using a wrench of course this won't be a problem but with a 4.5 inch lag and driving into a 2 x 10 the long way I really didn't want to get a workout with a wrench. Not a big problem but if the bolt were 1/8 shorter a ratchet / socket would fit perfectly over the lags with no concerns. Only a minor issue to get the added security of a heavy duty hanger. But enough to not give it 5 stars - still a very safe product
