![]() ![]() It is responsible for the safety performance of daily use door. The fire rated door mortise lock is the focus of fire door. To reduce the removal of timber from doors, the mortise locks should be as small as is practicable.A regular programme of maintenance must be undertaken to ensure that the correct operational performance is maintained for the life of the building.The locked doors on escape routes should be open-able by one hand operation.The mortise locks with low melting point (less than 800☌, or 900✬ for steel doors over 90 minutes resistance) components, which are critical to the retention of the door in the closed position, should NOT be used unless proven by specific tests.This evidence should be provided by an approved third party certification or testing body. The mortise lock must have demonstrated its suitability for the intended purpose by inclusion in satisfactory fire tests to BS EN 1634-1 or BS EN 1634-2, on a type of door and configuration in which it is proposed to be used.And preferably, should be provided with additional product.The following are suggestions for installing fireproof mortise locks: locks containing materials which might flame.using materials of low melting point (less than 800º C, or 900º C for steel doors over 90 minutes resistance) in components which, if they should melt, could cause a failure of functionality of the device.through fixings creating thermal bridges in a timber door,.adding materials which could cause heat transfer problems in a timber door,.leaving voids within the structure of a timber door,.removal of a section of the door leaf, door frame or seal,.In fitting locks to fire-resisting doors, the potential fire performance of a door might be reduced due to: a dispensary or a wages office, then hardware such as panic escape devices to BS EN 1125 or emergency exit devices to BS EN 179 should be used. Where the door will be normally locked during occupation, e.g. A thumb-turn on the inside of the door will give means of escape to anyone inadvertently locked in. ![]() Doors which are normally unlocked when the building or area is occupied may be fitted with locks for out-of-hours security. Where security is in conflict with easy egress, a full risk assessment should be made. This might be on a duct door which is normally kept locked with only occasional access to service equipment, or other fire-resisting doors which for security reasons are locked for periods of time. In certain cases there is a need for a lock to be fitted to a fire-resisting door. In the case of single action doors, this role might be undertaken by a latch. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).In order to provide an effective barrier to a fully developed fire, a door has to remain closed within the frame. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. Lorem Ipsum is simply dummy text of the printing and typesetting industry. INJIGC-MORT-CWB32: 1 1/4″ Wood Screw Cutter.INJIGC-MORT-CWB25: 1″ Wood Screw Cutter.INJIGC-MORT-CWB22: 7/8″ Wood Screw Cutter.In addition to the self-centering Mortise Jig with aluminum housing, carrying case and instructions, the Kit includes: And a power drill with a 1/2″ chuck running at speeds 2,000 – 3,000 rpm is recommended. This produces a very clean smooth cut and is one of the fastest most accurate ways to cut a mortise. It really is a simple process: mark the lock length on to the door, select the width of mortise cutter that suits your lock, set the depth collar, pass the drill shaft through the jig’s guide bush, lock the jig to the door and using power from your drill, drive the carbide tipped mortise cutter into the door moving up and down repeat process for the faceplate. This very precise drilling jig is designed specifically to guide the drilling bit to cut mortises for door locks and their faceplates. ![]()
