Use the two-way aluminum Chain-Link bullet cap on terminal corner posts to keep moisture and debris from inside of your fence posts. The cap features two built-in rail connectors, for 1-3/8in rails, and is compatible with 2-3/8in terminal corner posts. The two-way bullet cap is constructed of aluminum with a silver decorative finish to compliment Chain-Link fence posts. The bullet cap simply snaps onto the post for quick and easy installation.
