Description

RailFX FlexFX XL Stair Tensioner Cable Fitting for Composite Sleeve is a Push-Lock Fitting that holds the cable in place on horizontal runs for stair applications. This tensioner fitting is designed to install cable railing into a composite sleeved wood post 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. Pre-drilling with a 7/32" drill bit is recommended. 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.
