D and D provides a wide range of products for wooden and metal door applications.
such as Stainless Steel Door Hinges, Door Locks, Lever Handles, Door Closers, Exit Devices, Door Stopers, Door Bolts and Door Accessories etc, not only door hardware but also Door Opening solution.
The D and D door set product category covers mortice locks, European profile cylinders, lever handles and hinges. Since the dimensions of all these products comply with DIN standards (DIN 18251 for mortice locks, DIN 18252 for profile cylinders and DIN 18255 for lever handles), the products are compatible amongst themselves regarding their functionality. All parts of the functional units are also perfectly aligned with each other.
More contemporary versions of the barrel or slide bolt are the patio bolts, panic bolts and tower bolts. These are all surface bolts, some of which are lockable with a key and all of which are heavy duty and create a stronger design element. For example we sell a lockable polished brass patio bolt that not only provides security, but it also an architectural feature. It is a very durable and long-lasting door bolt and comes with an anti-tarnish brass finish. Our lockable bolts provide extra security and we supply two keys with each lock. If you are ordering multiple locks, these locks can be keyed alike (where one key works in multiple locks) or separately, whatever suits your needs best.
