KT-RN - BUTT HINGE FOR PVC-U DOORS

Low-energy and high thermal insulation values are buzzwords that currently accompany manufacturers of doors made of PVC profile sections through every stage of production. Energyoptimised system profiles with multiple sealing levels make a significant contribution to ensuring that the cold stays out and the heat stays in. The new three-piece Hahn KT-RN is based on this advancement which always leaves the seal unscathed without adversely affecting the desired look of a narrow butt hinge. With a hinge diameter of only 22 mm, it is one of the slimmest versions available on the market.

STURDY AND SUITED FOR ALL COMMONPROFILE SECTIONS

The hinge is able to support doors weighing up to 140 kg depending on the door frame situation. The door hinge achieved class 14 in the CE tests and is designed accordingly for doors subject to very high loads. The door hinge that is manufactured using extruded aluminium is provided for the most part factory-assembled. It can be used on either (left and right) side of the door without requiring any changes. With only one variation, the KT-RN accommodates all common profile sections with a rectangular upstand of 16.5 to 26.0 mm. In the same upstand range, another hinge variation with a specially developed door hinge contour allows for the use with frame combinations with an angled upstand between 4° and 6°.

Dr. Hahn – Hinges. Made in Germany
Innovation, high-quality products for doors and maintaining high service standards characterise the hinge manufacturer Dr. Hahn GmbH & Co. KG and its development over the years. Founded in 1961 by Dr. Walter Hahn, the company is now managed by his sons Michael and Walter Hahn and Eckhard Meyer.

The medium-size company has managed to make a name for itself internationally under the Dr. Hahn brand with its small but high-quality product range for doors. The door hinge specialist has continued to expand its sales activities year after year. While the annual turnover in 2001 amounted to EUR 37.6 million, the company had an annual turnover of EUR 45.2 million in 2005. A further increase of well above EUR 52.7 million is being reported for 2014.

The number of employees has also grown to 380 persons in 2016. In addition to Central and Eastern Europe, Dr. Hahn’s sales markets nowadays include Asia and America.

From First Idea to Customer
From the first idea through to surface refinement, all products are manufactured using state-of-the-art equipment at our factories in Mönchenglandbach and Erkelenz, Germany. That includes hinges for metal and plastic doors.

High standards backed up by constant quality control, ground-breaking new developments such as the first aluminium door hinges for front-side mounting have quickly made Dr. Hahn one of the market leaders in this segment.

High Quality
Maintaining this position over the long term has only been possible thanks to the qualifications of our employees and the particular quality of our products. Besides internal quality assurance of every single element, long-term stress tests and inspections are performed by approved external testing laboratories. As a result, it is possible to say that Dr. Hahn hinges are of “high quality” to the fullest extent.

Successful Presentation of New Products
Over the past few years, Dr. Hahn has impressively demonstrated why it ranks among the market leaders of this segment. More than 20 new products with genuine innovations and a wide variety of patents have been presented to customers.

For instance, our concealed VL Hinge ST for steel doors and VL Hinge AL for aluminium doors have drummed up a lot of interest. In 2012 Dr. Hahn presented the VL Hinge KT for PVC-U doors.
