White plastic key tags are perfect for offices, rental management companies and storage facilities. Sturdy, 1-1/4″ high, plastic key tags with write-on surface are attached to chrome-plated key holders and are designed to work with the SteelMaster Dupli-Key System that uses two different sets of numbered key tags and makes managing keys as efficient as possible. Simply attach your master key to the red octagonal-shaped, self-locking key tags (sold separately) to ensure your master original key is never loaned. Fasten the duplicate loaner key to these white, oval, snap-hook key rings and file on the same hook with the master key. Tags can be used alone. The write-on surface makes it easy to label or identify the key’s purpose. The hooks accommodate one or more keys.
