Introduction<\/h1>\n
Indicating bolts are specially designed door-locking mechanisms used in public baths and lavatories to indicate whether a toilet or washroom is occupied or vacant<\/strong>.<\/p>\n
These bolts are commonly found on doors in places such as public washrooms, railway coaches, aircraft, malls, commercial buildings and other high-traffic facilities<\/strong>. IS 4621:1975 specifies requirements for indicating bolts used for these applications, including requirements related to materials, dimensions, workmanship, finish, marking and packing.<\/p>\n
For manufacturers supplying indicating bolts in India, compliance with the applicable BIS requirements is important. IS 4621:1975 is included under Scheme-I of the BIS certification system<\/strong> and is covered under the Bolts, Nuts and Fasteners (Quality Control) Order, 2024<\/strong>.<\/p>\n
\n
About Indicating Bolts<\/h1>\n
An indicating bolt is a door-bolting mechanism designed to provide privacy while simultaneously showing the occupancy status of a room.<\/p>\n
The mechanism normally includes an indicator that changes its visible status when the bolt is operated.<\/p>\n
For example:<\/p>\n
VACANT \u2192 Door available for use<\/strong><\/p>\n
OCCUPIED \u2192 Door in use<\/strong><\/p>\n
This simple mechanism is particularly useful in public sanitation facilities where users need an immediate indication of whether a particular facility is available.<\/p>\n
\n
