Description

RailFX FlexFX Stair Tensioner Cable Fitting for Wood is a Push-Lock Fitting that holds cable in place on horizontal runs for stair applications. This Tensioner for Wood is designed to install cable railing with wood posts and has an adjustable design that can conform to virtually any angle. Fittings are driven into the posts and then the cable can simply be pushed into them. Make sure to fully insert cable into the fitting, as it is critical to fitting performance under tension. The cable will automatically lock into place without the use of any special installation tools, making cable installation a breeze. Cable can be tensioned by holding the tensioner body at 3/8 inch wrench flat nearest cable and rotating female threaded section of fitting with a 3/8 inch open-end wrench onto threads.

Typically, one tensioner and one non-tensioner is needed for each horizontal or stair run. If your cable run is greater than 50' or has more than two 90 degree turns, then a non-tensioner is not needed and instead use two tensioners for each run.
