Tight mounting spaces along level runs call for the 352-424: it holds a 1.67" OD pipe handrail at a 2" projection from the post, 1" lower than the Tall 350-424. That suits tight-profile details, a two-rail run with a child-height secondary rail, and retrofits where the taller version won't clear a renovated wall or ceiling. For sloped stair and ramp sections at the same projection, pair it with the Short Adjustable 352A-424; for a slope that bends in more than one plane, the ball-joint 821-424. Machined from 316-grade stainless in a satin finish, sized for .080" pipe wall, indoor and outdoor.
