CableRail Isolation Bushings by Feeney will help minimize electrolysis by removing direct contact of different types of metals when attaching cables and fittings to metal posts. Recommended for coastal regions or similar salt air environments. Made of an engineered polymer, they are highly resistant to abrasion and UV degradation, and have a wide temperature operating range of -40F to +266F. Silicone sealant (not included) will be required to fasten the bushings in posts. Sold individually.

Don't forget to order a Release Tool
Your installation could be delayed if you are unable to disconnect a cable from a Quick-Connect® fitting! We strongly recommend adding a Release Tool to every Feeney CableRail order!
