The door model Clue is sold out.

Clue is a limited front door developed in collaboration with Wonderwall Studios. The door is made of 100-year-old black oak. The wood used on the door leaf has been salvaged after being soaked in seawater or buried in the ground for a very long time. The color is black with shifts in brown.

Luxurious, elegant but above all unique are the words that best describe Clue. The black sign is sorted by shade and thickness, then each door is patterned by hand. Wonderwall Studios recycles old wood with a strong focus on the environment and upcyling. The material is picked up all over the world and you control the whole process from salvaging material, to sawing and hand polishing of every small piece. Local craftsmanship around the world is used to create new life in old materials.

Bog oak is rare and valuable, the material has often been hidden in land or sea for several hundred years, access is therefore limited. Ekstrands has materials for a handful of doors, depending on the dimensions of the doors, after which no more are manufactured. Each door will be numbered. With our love of wood, we continue the search for unique materials and exciting door designs, what the future will show. Clue, on the other hand, will never come again.

Thermo-treated oak black brown oiled
Oak from our own latitudes. We have thermo-treated solid oak so that the wood has a burnt, darker color. Thus, the wood has also gains a fantastic weather resistance. Hardwood is not discolored by spores or fungi in the same way as untreated oak. Even if you are careful and maintain oak, it takes an enormous amount of work so that the wood does not discolour. Hardwood requires less maintenance, even less than the rainforest wood teak which everyone knows is optimally weather resistant. The brown color lightens slightly over the years if you do not maintain it with a penetrating / wetting oil. Our thermo-treated oak is treated with a pigmented oil to maintain the dark color. Heat-treated wood is also used for e.g. terrace floor instead of pressure impregnated wood.
Standard white
Our standard white is a warmer off white. Ekstrands can also supply neutral white or any chosen colour.

Ekstrands offers a wide range of different locking systems, electronic controls, cylinders and fittings.

Pull handle and customisation
Ekstrands has a wide range of pull handles. When selecting a pull handle, you don't have a handle function, which means that you need a key-controlled or electrically controlled opening. For example, code lock or fingerprint reading. We recommend choosing a door closer when using pull handles.
Snap lock for pull handles
When choosing a pull handle, you usually need a so-called snap lock for the door to be locket when closed. These are combined with a cylinder and cylinder accessories, usually an oval cylinder with a knob on the inside. Snap lock 230 has a smart set-up button on the edge, snap lock 231 must be set up with a key (for public spaces)
Handle function with door knob
When choosing a pull handle, you usually need a so-called snap lock for the door to be closed and locked. If you want to keep the handle function and a regular lock, you can choose to set a knob that you can turn to get the handle function. Then the pull handle works more like a decor.
Smart lock for wall installation
With this wall reader you can control a motor lock or electric strike plate so that you can open the door wirelessly or via Bluetooth with your mobile phone, with a finger scan or PIN code. The smart lock is installed on the wall. The wall reader is a good digital solution to combine with both pull handles and traditional handles.
Smart locks
Ekstrands can prepare exterior doors for various smart locks and systems. Contact us for more information.
Hidden smart lock
Modern hybrid lock with technology so smart that it is invisible. All technology is hidden in the lockbox. You can keep the fittings and handles that fit your door. (Does not work with FSB handles)
Standard fitting set
Lock Dorma 919, press Dorma 7291 with oval single cylinder / knob
HOPPE fitting set
Hoppe fitting packages are optional, available in several different materials and colours. See separate tab for handle range.
FSB fitting set
FSB fitting set, available in several different materials and colours. All FSB handles are equipped with a double return spring, see separate tab for handle assortment.
Standard fitting set Comfort - Secure
Lock Dorma 9192 is optional and a so-called "comfort - secure" lock. It is a safety lock with a hook bolt that is equipped with a round cylinder inside and out, as well as an extra knob on the inside. With a small button on the locking post, you change the function of the lock, when you are away, the knob does not work on the inside, which makes it difficult for someone who has broken in, when you are at home you use the knob. Standard fitting package is Dorma, available in several materials and colors. Handle Dorma 7291 is included in the standard package.
HOPPE Comfort-Secure
Hoppe fitting packages are optional, available in several different materials and colors. See separate tab for handle range.
FSB with Comfort - Secure
FSB fitting sets are optional, available in several different materials and colours. All FSB handles are equipped with a double return spring, see separate tab for handle assortment.
Cylinder both sides
Round cylinder or oval cylinder both sides of the door. A round cylinder has higher safety compared to an oval. If you have a cylinder inside, you have also achieved internal safety, what is important to keep in mind are other escape routes for this alternative. Ekstrands has a wide range of cylinders and can also deliver cylinders in systems, keys ordered by key number, additions, etc.
Cylinder with accessories
Surface treatment equal to door handle can be ordered, these are not included in the door price. Both 701 and 712 cylinders fit standard locks, the 701 has an internal knob and the 712 key on both sides. Only 712-cylinder with "home-comfort / away-safe" accessory fits lock box 9192. Brass, matt chrome and stainless steel are standard. Views of the various cylinders can be downloaded, these are good help during assembly.

Door and side lights are delivered assembled as one unit.
