A standard coupler is rated at 12.5 kN slip, so safety couplers are only required if the load exceeds 20 kN Standard couplers cannot resist any slip along the standard, so they are only used to align the tubes A standard right-angle coupler is rated at 6.25 kN slip, and a safety (check) coupler is added directly underneath to act as a physical stopper in case of slip Safety couplers are only required if the spur is angled steeper than 75 degrees
