Because of the loss of keys for my front door, it became necessary to change the existing Chub lock. I searched all local ironmongers for a 5 lever lock of similar proportions, to no avail. I then did a search on the net ,and I found to my delight, the Union lock which was suitable in every dimension to fit my door , avoiding major alteration to the door cavity. It was a rare experience to find, that over a long period of time, the dimensions had not been changed, in order to create obsolescence.

The product was ideal for our needs, the assistant I spoke to on the phone was extremely knowledgeable about your range of products and pointed me in the right direction on what exactly I needed. I cannot fault your service and products at all. Good look to you. I will certainly use you again and highly recommend you to others when the need arises.
Also I found you through your website which is excellent.

This lock was to replace an old unit, so had to fit the old slot and keyholes. I had tried a unit from another source which had the correct spec but didn't fit. This lock arrived well packaged within 48hrs of order. It fitted perfectly. Replacement was as simple as could be wished for. The lock is in constant use and appears to be very robust. We have had no problems with sticking & the keys fit well & turn effortlessly. I have absolutely no reservations in recommending this product as a very good quality, sturdy, easily fitted, well constructed lock.
