Mount a handrail to a round 1.67" OD post or pipe and let the bracket do the fitting for you. The coped back plate wraps against A114 1.67" (42.4mm) x.080" wall structural tubing for a clean, flush seat, and the receiver takes a standard 1.5" handrail, so a structural post and a graspable rail work together on the same run. The adjustable joint covers 2" of height plus unlimited pitch and rotation, which lets one bracket square up to a raked stair, a sloped ramp, or a level landing without shimming. It is built from 316-grade satin stainless steel, marine-capable for damp and coastal settings, and meets IBC and ADA handrail requirements. Part number 49-309P/424.
