Brass door fittings
Fire protection fittings are prescribed in many public buildings and must fulfil special requirements in the event of fire: It must be ensured that the door fitting also functions for a considerable time to allow an escape.
Traditional door fittings made of brass are not suitable for this, as brass, being a comparatively soft material, cannot withstand high temperatures.
We therefore offer special door handle sets made of stainless steel - modern material but still with a traditional design!
The fittings are designed to meet the strict requirements of fire protection regulations (certified to DIN 18273 / DIN EN 1906, Cat 4).

Knob/handle-set / handle set
Today, entrance door fittings are usually designed as knob/handle-sets. A knob/handle-set refers to the combination of a stationary knob or pull handle on the outside and a moving handle on the inside of the door. The knob and lever handle are connected by a rotatable knob/lever spindle. The door can only be opened from the outside with the key.
The door set can also be manufactured as a handle set. In this design, the door can be opened from the outside and inside with the lever handle, but it is not locked. As a special variant, we also offer these sets with a stationary knob on the outside or with a rotatable knob. Side of hinges - DIN left / DIN right
We need you to specify the side of hinges for this door handle. For doors that open inwards, the side of hinges are named as follows:
- standing on the inside of the door, pulling the door open towards you: The door is mounted on the left side of the frame - DIN left side of hinges
- standing on the inside of the door, pulling the door open towards you: The door is mounted on the frame on the right-hand side - side of hinges DIN right
Material and surface
Our fire protection sets are made of high-quality V2A stainless steel.
They are available in four different surface finishes, so that they each have a different appearance:
* antique patinated - matt-brownish colouring
* mirror-polished - high-gloss silver-coloured
* brass-coloured - shiny gold-coloured (PVD-coated)
* matt black - powder-coated to resemble ironDistance / euro profile cylinder perforation
Fire protection sets are supplied with euro profile cylinder perforations (abbreviation: PZ) for mortise locks as standard. The door plates have a perforation for the knob or lever handle and a perforation for the profile cylinder. For fire doors, a distance of euro profile 72 mm is usually standard, measured from the centre of the handle hole to the centre of the round part of the cylinder hole.
Different distances or round cylinder holes are also possible,
The distance is not relevant for door sets with roses.Door thickness / spindle
Knob/handle-sets have a rotatable knob/handle-set pin that is screwed into the M12 thread of the knob. The standard pin for fire protection sets has a thickness of 9 mm x length of 90 mm.
Knob/handle-sets or handle sets with a handle on both sides are also supplied with a 9 mm spindle.
On request, the knob/handle-sets or handle sets can also be supplied with an 8 mm spindle and a different length.
Please specify your door thickness when ordering!Mounting and security
The lever handles are firmly mounted on stainless steel plain bearings on backplates or roses.
The outside backplates and outside roses have stainless steel threaded cams on the back for invisible screw fixing through the door on one side.
The mounting is carried out using the M8 stainless steel pan-head screws supplied.

Installation instructions
All assembly work should be carried out by a specialist (carpenter). They have the appropriate special tools and expertise to carry out the mounting without any problems. We accept no liability for damage caused by improper mounting.If you want to do the mounting yourself, here are some tips: The mounting of entrance door fittings requires precise work: The door must be drilled through exactly at right angles at the specified distances in order to be able to insert the threaded screws. The spindle is screwed into the thread of the knob and the supplied sleeve (for locks with a 10 mm follower) is fitted onto the spindle. The knob/lever spindle is inserted through the lock follower and the knob long plate or the knob on rose is fitted. For precise alignment of the backplate, it is advisable to insert the profile cylinder in advance. The inside plate is placed on the door and loosely screwed to the outside plate using the threaded screws. If the screws or knob/lever spindle are too long, they can be shortened with a hacksaw. The lever handle is placed on the spindle and loosely mounted to the spindle using a grub screw. Only when the plates or roses are precisely aligned is the final mounting carried out. Door plates or roses are then mounted on the door leaf using additional wood screws.
