Fitting the Minster Latch


Decide the optimum position for the assembly on the door, normally mid-way or approximately 46 inches from the floor. Mark this on the door. Ensure that the latch-guard, when fitted, will straddle the centre ledge.

Position the latch so that it is level, rests on the lower edge of the latch-guard recess and extends to engage with the keep. Mark the position of the latch on the door and the position of the keep on the doorpost.

With the 7mm bit, drill the pivot end of the latch to take the pivot nail loosely - the objective is to fit the pivot nail tightly into the door but loosely through the latch end so that it will move easily on the nail.

If necessary, with a hacksaw, shorten the pivot nail so that when fitted it will not protrude through the door. Take care to include the length of the nail required to pass through the latch. With the 2mm bit, drill a pilot hole on the door to receive the pivot nail firmly.

Offer up the pre-drilled keep to the doorframe so that the latch sits nicely in the recess of the keep. Using the 2.5mm bit, drill a pilot hole into the door frame to take the keep fixing screw.

Apply glue to the keep and tighten the fixing screw. With the 2.5mm bit, drill through the existing lower hole of the keep and about 3/4inch into the door frame and tap home the 50mm nail, taking care that the nail at its widest goes with the grain of the keep.

With the latch level, in position and located in the keep, offer up the latch-guard so that it is approximately 4½'' from the pivot nail end of the latch, with the latch resting on the lower end of the latch-guard recess. Using the clamp, hold the latch-guard in position and mark the position of the screw holes on the door.

With the latch end located in the keep & taking careful note of the position the latch-guard will occupy, mark a point approx 2'' to the right of the latch-guard and immediately below the latch.

Swing the latch out of the way, using the 16mm bit drill through the door. Using the chisel, square the hole, making sure that the trigger sits easily. Next, enlarge the height of the exit aperture by 50% and ensure that the trigger, when operated will lift the latch.

With the trigger in place on the handle side of the door, locate the handle so that the upper edge of the trigger shaft is level with the upper edge of the handle recess. This will allow room for the trigger elbow to drop into the vacant area below the trigger when it lifts the hatch.

With the handle located and the trigger in place, mark the position for the handle fixing screws on the opposite side of the door so that they will will come through the door and into the handle. The best places for these are 1'' below the handle ledge and 1½'' apart.

Mark the door with the appropriate corresponding position, and using the 3/8 inch spade bit, drill through the centres of the two 3/8 inch holes so that the two 50mm handle fixing screws pass easily through the door.

Mark the position of the two screws on the back of the handle, and using the 3.5mm bit drill two pilot holes into the handle, making sure that the holes are drilled straight and that they are no deeper than 1¼'' inches.

Place the trigger in the position in the handle, apply the glue to the handle and screw it to the door, making sure that it is level and has not moved out of alignment during fixing. Fit and glue the two oak plugs.

Apply the glue to the latch guard and clamp in place, ensuring that the latch rests on the lower edge of the latch guard and insert the two 40mm screws. Glue and insert the two oak plugs and carefully trim off the excess taking care to cut downwards with the slope of the latch guard – sand as necessary.

NOTES: If the door frame is to have protruding architraves, fit the latch before fitting the architraves. If the door will open against a wall, take care that the end of the trigger does not hit the wall. Do not mix components of different sets.
