Fence and Deck Rite Adjustable Baluster Connectors are designed to fit the baluster to the top and bottom of your stair railing. Our Adjustable Baluster Connectors have an adjustable range of 29-to-45-degrees, which will ensure you hit the target angle of your stair. This will secure and support the integrity of your railing over time. As with all Fence and Deck Rite products, they are easily and quickly installed. We recommend using # 8 deck screws.
