Customer Questions & Answers

  • Question: What is the L-1172C National Mailbox Lock Replacement?

    Answer: The L-1172C National Mailbox Lock Replacement is designed specifically for USPS-style boxes, including those in cluster mailbox units (CBUs). This lock offers a robust mechanism that ensures the security of your mail. With compatibility for CompX L-1172C locks, it is ideal for replacing worn or damaged locks. Users often experience enhanced peace of mind knowing their mail is secure, making it a popular choice for residential and commercial properties with centralized mail delivery systems.
  • Question: How do you install the L-1172C mailbox lock?

    Answer: Installing the L-1172C mailbox lock is straightforward and requires minimal tools, typically just a screwdriver. First, remove the old lock by unscrewing it from the mailbox. Next, align the new lock into the designated space and secure it with screws. This lock aligns perfectly with USPS specifications, making the installation an ideal DIY project for those looking to enhance their mailbox's security without professional help.
  • Question: How many keys come with the L-1172C lock pack?

    Answer: Each L-1172C National Mailbox Lock pack comes with three keys. This ensures that you have enough spares in case one is lost, providing convenience for households or businesses that may need multiple authorized users. Additionally, having multiple keys can facilitate shared access among family members or staff, making it a practical choice for cluster mailbox scenarios.
  • Question: Is the L-1172C lock compatible with all mailbox types?

    Answer: The L-1172C lock is specifically designed for USPS-approved cluster mailbox units and CompX L-1172C locks. While it may not fit all mailbox types, it perfectly suits USPS-style mailboxes and cluster setups commonly found in residential areas. This lock's compatibility ensures that users can upgrade their locking mechanisms without worrying about proper fitting, promoting higher security standards.
  • Question: What materials are used in the construction of the L-1172C lock?

    Answer: The L-1172C mailbox lock is constructed from high-quality, durable materials designed to withstand outdoor conditions. Its metal body resists corrosion, ensuring longevity even in harsh weather. Furthermore, the robust internal mechanisms provide superior security against tampering and unauthorized access, making it an ideal choice for both residential and commercial applications, where safety is a priority.
  • Question: Can the L-1172C lock be rekeyed?

    Answer: The L-1172C mailbox lock is not designed to be rekeyed. Each lock comes with three unique keys that are intended for use with this specific lock unit. If you require changes in key access, acquiring a new set of locks is the recommended approach. This ensures that security remains intact and prevents potential risks associated with having rekeyed locks that might not offer optimal performance.
  • Question: Are there any additional features of the L-1172C lock?

    Answer: Beyond its basic functionality, the L-1172C National Mailbox Lock includes a robust design that enhances security and user-friendliness. It features a smooth locking mechanism that prevents jamming, which is particularly important for frequently used mailboxes. Users report a significantly improved experience with these locks compared to older models, making them a smart upgrade for high-traffic mailboxes.
  • Question: Where can I buy the L-1172C mailbox lock in Central African Republic?

    Answer: You can purchase the L-1172C National Mailbox Lock Replacement at Ubuy in Central African Republic. Ubuy offers a wide selection of mailbox locks, ensuring you find exactly what you need for secure mail delivery. By shopping through Ubuy, you gain access to reliable service and product authenticity, facilitating a seamless shopping experience for your mailbox security needs.
  • Question: Is there a bulk purchasing option for the L-1172C lock?

    Answer: Yes, the L-1172C National Mailbox Lock is available in packs, such as the ten-pack option. This bulk purchasing allows you to outfit multiple mailboxes or ensure spares for larger facilities or residential complexes. Buying in bulk not only provides cost advantages but also ensures consistency in security mechanisms throughout multiple units, simplifying maintenance and key management.
  • Question: What should I do if one of my keys gets lost?

    Answer: If you lose one of your keys, it is important to keep security in mind. Since the L-1172C lock comes with three keys, you still have access to your mailbox with the remaining keys. If you feel the need for additional security, consider replacing the lock. Ensuring that no unauthorized access can occur after losing a key is crucial, especially if the key was in a publicly accessible area.
