Description Use these post caps to attach a flat toprail to your square stainless steel terminal corner posts. Order one for each single-post corner of your railing system. Note: Stainless Steel is highly resistant, but not impervious to the elements, and requires minimal maintenance for ideal results. We recommend applying Passivator to all exposed stainless steel components at the time of installation. In addition, apply Rust Rescue if within 10 miles of a marine environment to further protect the stainless steel.

Secure to wood top rails with #8 x 1.25″ Flat Head Screws or metal top rails with 10-32 x 1/2″ FH PHIL T/F 410 Screws. Product # 982819
