To adjust a surface-mounted or flush-mounted drop threshold, whether you want to shorten it while maintaining its optimal operation, here are the steps to follow. This procedure is particularly useful when the need to reduce the size of the threshold also requires moving the mechanism to the correct side (hinge side):

  1. Remove existing mechanism

    - Locate the screw at the back of the drop sill. This screw holds the mechanism in place, including the pine that activates the lowering mechanism. 
    - Unscrew this screw using a suitable screwdriver.
    - Use pliers to grasp and gently pull the pine to remove the entire mechanism from the sill. 

  2. Reposition the mechanism

    - Insert the mechanism on the opposite side of the threshold. Make sure it is fully inserted and aligned correctly to allow smooth action of the lowering mechanism. 
    - Screw the mechanism into place in the hole on the opposite side to the first location. This involves drilling a new hole or using a pre-existing hole adapted to the new position. 

  3. Cut off excess

    - Once the mechanism has been repositioned and secured, measure and mark the part of the sill protruding from the handle side.
    - Use a suitable saw to cleanly cut the excess sill. Make sure you cut straight and cleanly to avoid damaging the sill or the mechanism. 

It is important to proceed with care at each stage to avoid damaging the sill or the mechanism. Make sure that the mechanism functions correctly after repositioning and cutting. This method allows you to adjust the size of the drop sill while maintaining its functionality, ensuring that the drop mechanism is correctly positioned on the hinge side for optimum operation.
