Abstract: A finger protection device (S) includes a housing (2), a first fastener strip (4) and a web (1), wherein the housing can be fastened to a door frame (R), or to a door leaf (F), such that, when the device is used as intended, the web (1) covers a gap between the door leaf (F) and the door frame (R). A second fastener strip (3) can be connected to the first fastener strip (4) in order to tension the web (1) between the housing (2) and first fastener strip (4). The second fastener strip (3) can be hooked in the first fastener strip (4) in order to tension the web (1).

Abstract: A finger guard device for a pivotable leaf door has a roller screen housing, a roller screen web which has a fastening means, and a mounting profile. The finger guard device can be fastened to a door frame by means of the housing and to the leaf door by means of the mounting profile. The fastening means of the roller screen web can be connected detachably to the mounting profile so that the roller screen web covers a gap between the door leaf and the door frame when the finger guard device is used as intended. The mounting profile has a supporting leg for placing on and fastening to the door leaf. The mounting profile is in the form of an angled profile and has a fastening leg, which projects beyond the supporting leg, for detachably fastening the fastening means of the roller screen web.

Abstract: A marking-out aid for application of an installation marking on an object, in particular on a building element, has a first stop surface (20) for the defined contact of the marking-out aid on the object, and also at least one first feeedthrough opening (4) for receiving a marking tool (B). The marking-out aid has a basic body (1) and a first cross bar (2). The al least one first feedthrough opening (4) passes through the basic body (1). The first cross bar (2) is arranged at a first end of the basic body (1) and runs at a right angle to the basic body (1). The first cross bar (2) projects over the basic body (1) on at least one side, wherein that side of the first cross bar (2) which faces away from the basic body (1) forms the first stop surface (20). This marking-out aid is suitable in particular for the installation of finger protection roller screens and finger protection strip covers of doors.
