Middle Frame Fitting is heavy duty cast aluminum and fits schedule-40 2" inner diameter pipe for both the top rail and the legs or 2-3/8" O.D. top rail and legs. 10' long legs (with none cemented/buried) would create a 9' high beam. Set screws are included. Middle frame connector is needed when more than one swing bay is desired on the same swing set.
NOTE:Â There is a stop in the middle of this fitting. It is designed for joining two beam pipes, it will not allow a pipe to pass through.
