The Howsarlock

– Portable Door Lock

The original toughened nylon ‘Howsarlock’ is still being manufactured and selling well. Due to the demand, we now manufacture the lock-in metal. This has been tested and clearly proven to be even more robust, withstanding greater more extreme aggravated force.

Testing has been carried out by ‘Solid Secure‘ where it was awarded a Bronze rating as being suitable for mechanical security of domestic buildings.

Thanks to our customers

Just a few kind words from people who have purchased our locks.

You can carry it through airport security fine.

If I was a backpacker, especially female, and doing a lot of hostels I’d invest £4.99 in a ‘Howsarlock’ …Very useful for bedrooms and toilet doors.

Team Geared Up

Most grateful for my Howsarlock.

I am an academic specialising in cross-cultural psychology so travel extensively, sometimes to places where the door security is to put it mildly – a little questionable. I therefore am most grateful for my Howsarlock and have used it throughout the world, as well as recommended to many other travellers.

Professor Robin Goodwin

The lock is a simple idea… to keep unwanted intruders out of the room.

 The paranoid traveller will never again lose sleep worrying about housekeeping and no one will need to use a propped chair to lock an unlockable door again.
