Protect your cable, fittings, and posts from electrolysis by installing DesignRail® Isolation Bushings in your DesignRail® Aluminum Post Kit openings to eliminate direct contact of dissimilar metals. Electrolysis occurs when two unlike metals connect, especially in coastal regions with strong salt air, or other areas with similar harsh elements. These Isolation Bushings essentially create a buffer between these two metals to eliminate any interaction between the two materials.

These Isolation Bushings are highly resistant to both abrasion and UV degradation while still having an operating temperature range of -40°F to +266°F. Isolation Bushings are packaged to perfectly accompany DesignRail® posts. Choose from bushing packages for a Level Quick-Connect® Post, Level Corner or Intermediate Stair Post, Level Threaded Terminal Post, Level Intermediate Baluster, Stair Quick-Connect® Post, Stair Threaded Terminal Post, or Stair Intermediate Baluster.

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!
