Whitco Security Locks

I rang this distributor on the other side of Australia on the off chance that they could help me. We are from Queensland,and were desperate to replace our corroded door handles with locks to fit our existing sliding glass doors.. Noone else could help us. Everyone that we enquired with said that those particular door handles were no longer available and we would have to buy 4 new sliding glass doors, but John was amazingly helpful and patient,and took the time to work out what combination had been used and what we would need to make it work.. Top marks..
Thank you John..
