The 19E-8 Double Adjustable Socket Tee works with the SnapNrack Series 200 Ground Mount System and is typically used to attach two diagonal braces to support posts for additional stability. It will fit any schedule 40 or 80 1-1/2" IPS. This aluminum-magnesium alloy fitting is as strong as steel, but 1/3 the weight, and can be used with galvanized steel with no concern for galvanic or dissimilar metal corrosion. The system uses set screws that penetrate the surface of the pipe to ensure that fittings are electrically bonded to pipe and bracing, eliminating the need for added bonding components such as jumpers.
