Window handles

Classical window handles

Window crutches are used especially on turning windows where the lock is inside the window. A window lock in the window became an alternative to window locks which were placed on the window. Originally these were mainly simple locks in the window and today multi-point locks or three-point locks are also used. Traditional window handles are screwed directly into the wood with screws during installation. For turn-tilt windows, other systems with a center distance of 43mm and 90 degree positions are used which can be found with the turn-tilt systems. The classic window handles have too small holes (smaller than 5mm for M5 bolts) and often also a deviating center distance between the holes which makes them not (directly) suitable for Tilt&Turn windows.

The application of the classic window handles is very important.

Application of traditional window handles

The traditional window locks are in most cases provided with a 7mm hole and the window handles therefore all have a 7mm pin and/or hole. For 8mm holes, you can also find spring pins on the site that are 7mm on one side and 8mm on the other.
