About Howsar Portable Lock

How did the Howsarlock come about?

After forty years teaching Design & Technology and having taken retirement I continued to have an interest in designing.  In 2006 I developed the Howsarlock, not thinking at the time that the lock was likely to ever reach the production stage!

My initial idea was to produce a simple locking device for domestic use. I saw the need for a portable locking system for use on internal doors. After considerable time and effort designing the lock I decided to have a prototype professionally made.  After minor modifications, I was happy with the final design.

I was fortunate to receive financial help from the Wales Innovators Network sponsored by the Welsh Assembly Government.  I was invited to exhibit my lock at the British Invention Show in London – the result being a Silver Medal! Following this I exhibited at the worldwide Inventors Show held in Geneva and this resulted in Howsarlock winning a Gold Medal! We were on our way!

The lock has a number of unique advantages

  • Made of reinforced nylon or steel and aluminium alloy, lightweight and inexpensive
  • Simple & quick to install & release – a matter of seconds
  • Adaptable to most inward opening doors
  • Unlikely to damage the woodwork of the door and frame
  • A simple design incorporating only 2 parts with a connecting tie
  • Small enough to fit in the palm of the hand

The lock is currently selling worldwide with positive feedback.  As well as the general public, a number of stores, travel companies, sports shops and security companies purchase our locks – most of these loyal customers date back 10 years.  More recently a number of schools and colleges both at home and abroad have bought the locks.  The locks are being used for college guests’ accommodation and for “lockdown” situations in schools.

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.
