Summary: The Adjustable Handrail Bracket for Square Posts (49-309PF/1H) is a flat-back adjustable handrail bracket from Lavi Industries that mounts to a square post or other flat metal surface and carries a 1.5-inch OD round handrail. It is the rail square bracket for the Lavi 316 square post railing systems. It creates a second, graspable handrail beside a glass, cable, or cross bar guard. The 309 series adjusts up to 2 inches in height with unlimited pitch and rotation, so one bracket follows a stair, landing, or ramp. The flat-backed plate matches the stem diameter, and the bracket is designed to meet building code clearance requirements for handrails. It is made in 316 satin stainless steel, rated for outdoor and coastal use, and pairs with Lavi A110 1.5-inch tubing and Loctite 326 metal adhesive. It ships from US inventory, and a flat-saddle version for square top rail is the 309PF/F.
