The door and window wedge offers a versatile and practical solution for securing doors and windows. Its sophisticated design enables doors to be blocked particularly effectively by reliably ensuring the desired hold. Thanks to the integrated suspension ring, the wedge can be attached directly to the door handle so that it is always to hand. The door wedge is suitable for doors with a gap of 2 to 50 mm and can also be used for windows to prevent unintentional closing or opening.
