![]() Typically used with a lever handle set.Ī lock mechanism incorporating a deadbolt only. Sashlocks can be key operated with a lever mechanism or cylinder operated and can incorporate thumbturns for keyless egress applications. When aligned correctly, fit the two remaining screws.Ī lock mechanism incorporating both a latch and deadbolt feature. Test the complete lock for working operation, and adjust the position of the box striker if required. Secure the box striker using the screws supplied in the central or elongated holes only. Remove the box striker and chisel out, so the box striker sits flush within the door frame. Re-hold the box striker to the door frame and draw around the edge. ![]() On the door frame draw around the box section of the striker.Īlong the vertical line, drill a series of overlapping holes to the box striker depth. Hold the box striker on the door frame, ensuring the box section is in line with previous markings. Between these two lines mark a central vertical line (dotted line) on the door frame. Mark the positions of the bottom of the bolt and the top of the latch bolt. To fit the box keep/ striker, with the door open and the bolt in the locked position, close the door gently against the door frame. Then fit escutcheons and/or door handles with the spindle cut to suit. With faceplate in position, secure the lock into the door with screws provided. Please note: when fitting a Euro sashlock, insert the cylinder retaining screw through the lock before fitting the faceplate in position. Place the lock into the door making sure that the key (and spindle) pass freely into the lock. Mark the position of the keyhole (and spindle if applicable), drill and cut holes on both sides of the door for the key (and spindle). Hold the lock against the face of the door ensuring the faceplate is flush with the door edge and in line with the lock recess. The curved edge of the sashbolt (latch) must be facing the door frame, if not, the sashbolt must be reversed (instructions). With the lock fitted in the door, check the sashbolt is suitable for your door opening. Please note: if you are fitting a sashlock, please check handing. The faceplate should be flush with the door edge. Place the lock into the door and ensure a good fit. Remove the lock from the door and then chisel the marked recess to accommodate the lock faceplate. Insert the lock body into the door and draw around the forend on the door edge (remembering to add the removable faceplate before tracing the outline). To drill to the correct lock depth we recommend applying adhesive tape to the drill bit to the measured lock depth (including forend and faceplate depth).Ĭarefully chisel out the remaining wood to make a rectangular hole (mortice) to accommodate the lock body. Please note the hole on the diagram marked * is for use only with cylinder mortice door locks.īetween the two lines, vertically mark the centre (dotted line) and along this vertical line drill a series of overlapping holes to the required lock depth. Hold the lock body against the door edge and mark the top and bottom of the lock body on the door edge (avoiding joints of cross members in the door). Position the lock body mid-height on the door, or as close as possible. The end of the faceplate may be squared or round. The width of the forend/faceplate (the part that is visible once the lock is fitted). The overall length of the forend/faceplate (the part that is visible once the lock is fitted). The height of the lock case, measured from top to bottom. However, please check before installing, especially if you are replacing an existing lock. Typically in the UK case depths are generally either 64mm (2½”) and 76mm (3”). The depth of the lock when routed into the door, measured from edge to edge. ![]() This dimension isn’t required for a deadlock as there is no handle. Measured from the centre of the keyhole/ cylinder to the centre of the follower hole (the square hole the handle spindle passes through). Typically a lock adjacent to a glass panel will be 2½” (44mm) and otherwise 3” (56mm), but you should always measure to be sure. Most backsets are commonly measured at either 44mm (for a 64mm (2½”) lock) and 56mm (for a 76mm (3”) lock). The five key dimensions are shown in the diagram below (sashlock shown): Dimension A: Backsetīackset is measured from the centre of the keyhole to the edge of the lock. A drawing of the individual lock (found in the fitting instructions or technical data sheet) is useful for routing information if you are fitting the lock into a new door. ![]() When fitting or replacing a mortice lock there are a few measurements required to ensure that you purchase the correct lock for the application.
