Flush fittings keep a railing's connections smooth and low-profile, but their outlets come at fixed angles. When a 2" OD run has to meet a flush fitting at an angle the standard outlets don't cover — a stair rail following its own rake, a bar rail turning at an odd corner — the Flush Angle Collar makes the connection at the angle the layout needs, in a shape that sits tight against flush-style fittings. It measures 2" across and stands 7/8" tall, sized for 2" OD, .050"-wall tubing. Cast in polished brass to match a traditional brass rail. It pairs with flush-style fittings only; for ball fittings, use the 800 Angle Collar instead.
