This is a traditional iron latch mechanism fixed to wooden doors, consisting of a sliding iron bar that moves sideways to lock and unlock the door, with riveted plates and a slot to hold the bar securely in place; often, a padlock or pin was added through the side hole for extra security. Such latches were widely used in old houses, temples, and warehouses before modern locks became common, and were locally forged by blacksmiths (ಕಮಾರರು – Kammararu) by hand, ensuring strength, durability, simplicity, sturdiness, and long life.
