Hoppe 10 year operational guarantee

According to HOPPE, a brand name product keeps its promise of quality to the end user. As a way of ensuring this, HOPPE gives a 10-year guarantee on all door and window handles (as long as the respective assembly and maintenance guidelines are fulfilled).

HOPPE brand name products undergo numerous tests to ensure flawless operation. Static impact tests and durability test also made according to the product type. These closely reflect the everyday knocks hardware has to take and extend beyond the tests and requirements of DIN EN 1906 or RAL-RG 607/9.

Whereas for DIN EN 1906 and RAL-RG 607/9 hardware is tested in isolation, HOPPE, more realistically, conducts operational tests on the door and window itself. This means that not just the function, but also the durability of the attachment between hardware and door or window, too, is tested. The number of operation cycles here is far higher than those demanded by the standards mentioned above.

With the 10-year operational guarantee, HOPPE extends beyond the statutory 2 years of European regulations, thereby setting the new quality standard for brand name hardware.
