Section I: 1. Accurate Measurement and Selection of Hinges

Prior to commencing the installation procedure, meticulous measurement of the door and framework is paramount to selecting the most suitable concealed door hinges. Imprecise measurements could lead to subpar alignment, potentially causing the door to stick or resist closure correctly. For an impeccable installation, adhere to these guidelines:

a) Ascertain the door and frame thickness to identify the precise hinge dimension.

b) Inspect the door and frame width to guarantee ample clearance for the hinge assembly free from interference.

c) Confirm the door swing orientation to select the corresponding hinge variant (right-handed or left-handed).

Section II: 2. Door and Frame Preparation

Thorough preparation is indispensable for a triumphant installation of concealed door hinges. Adhere to these fundamental steps:

a) Sanitize the door and frame surfaces to eliminate any dust, detritus, or grease that might obstruct the hinge installation.

b) Examine the door and frame for any anomalies that might impede the hinge fitting. Smooth out any rough edges or defects.

c) Mark the hinge positions on the door and frame employing a level and a graphite pencil to ensure even spacing and perfect alignment.

Section III: 3. Precision Hole Cutting

Hole cutting accuracy is paramount for a successful installation. Follow these steps:

a) Employ a drill bit marginally larger than the hinge pins to carve pilot holes for the hinge screws.

b) Align the hinge template with the designated locations and secure it to the door and frame with adhesive tape or a clamp.

c) Drill the hinge holes per the template, ensuring the drill bit remains perpendicular to the door and frame surfaces.

Section IV: 4. Partitioned Installation of the Hinges

With the door and frame prepared and the hinge holes cut, it's time to install the hinges:

a) Position the hinge pins through the holes in the door and frame, ensuring they align with the hinge cups.

b) Insert the hinge cups into the hinge holes, and gently tap them into position with a mallet to secure them.

c) Attach the door to the hinges via insertion of the hinge pins through the door and frame, ensuring the door is level and aligned with the door frame.
