The family business of Derrick Purdue and his sons, Sinclair and Julian, started out in small premises, with 3 staff members, in 1982 in Cape Town’s CBD, importing and assembling CISA padlocks.
Their passion was to supply high quality locking devices in South Africa, whilst creating employment that was fair and uplifting. Our people, been given the opportunity, have grown from general workers to become sales managers, credit controllers, supervisors, master key planners and product specialists.
Today, D. Purdue & Sons is the proud sole importer and distributor, into South Africa and Sub Saharan Africa, of CISA branded locks from Italy, stocking over 3500 CISA products. We currently employ 80 staff members at our Cape Town Head Office, with offices in Johannesburg and Durban.
CISA – an Allegion Company – is the leading brand in Europe and South Africa, in the Lock Security and Access Control System sectors. With six manufacturing plants, and a worldwide distribution network in over 70 countries, CISA has a pre-eminent role in the international market. Almost all of the 30 000 products available in the CISA Catalogue are manufactured, tested and certified according to the European Norms – a stringent set of prescribed Standards that are accepted in over 32 countries in Europe.
D. Purdue & Sons and CISA have forged a close, highly successful partnership over the years. CISA has the vast product range, manufacturing capacity, intellectual property and cutting edge R & D, while D. Purdue & Sons has the assembly capabilities, over 30 years industry experience and product expertise, enabling us to assemble over 500 different types of cylinders, padlocks and locks, to customer requirements and specifications.
