Tubular Lock

A tubular lock, also known as a radial pin lock, is commonly used in cabinets, lockers and vending machines. It features a circular key design that offers smooth operation and moderate security for internal applications.

A tubular lock can be replaced with a higher-security alternative such as a euro cylinder if the application requires stronger protection. Always ensure that the replacement fits the door’s cut-out and backset dimensions.

The main vulnerability of a tubular lock is that it can be picked using specialist tools if it lacks anti-pick features. Choosing a reputable brand with security enhancements reduces this risk significantly.

A tubular lock should be kept free from dust and lubricated occasionally with a dry graphite lubricant. Check the keyway for debris and ensure the locking cam operates smoothly to maintain functionality.
