Tools You May Need

• Allen key 
• Tape measure and pencil
• Level
• Chisel (for mortice lock installation)
• Screws and anchors
• Safety goggles

A. Cabinet Hardware

(Pull Bars, Knobs, Drawer Pulls)

Step 1: Mark Drilling Points

Use a measuring tape and pencil to mark hole placements. For uniformity across multiple pieces, a template is recommended.

Step 2: Drill Holes

Drill through the surface using a bit that matches the provided screw diameter. Keep the drill straight to avoid angle misalignment.

Step 3: Mount the Hardware

Insert screws from the inside of the cabinet or drawer. Secure the hardware on the front face and tighten with a screwdriver — avoid overtightening.

Step 4: Align and Inspect

Confirm straightness and spacing before fully securing.

B. Door Handle Hardware

B1: Thumb Lock or Dummy Handle

Step 1: Confirm Orientation

Determine left-hand or right-hand door swing. Adjust handle orientation as needed.

Step 2: Mark Installation Height

Mark desired height (typically 36–38 inches from the floor to the handle center). Align the mounting plate accordingly.

Step 3: Drill and Attach

Drill pilot holes and secure the backplate and handle with the included screws. For dummy handles, install directly without latch mechanisms.

Step 4: Install Strike Plate (Thumb Lock Only)

Mark latch location on the door frame. Chisel a recess if needed and screw the strike plate into place.

B2: Mortice Lock Handle

Step 1: Cut Mortice Pocket

Using a chisel and drill, create a cavity in the door edge for the lock body. Use provided measurements for accuracy.

Step 2: Insert Lock Body

Fit the lock body into the mortice cavity and attach it using screws through the faceplate.

Step 3: Install Handle

Align the spindle through the lock and attach handles on both sides. Tighten using a screwdriver or included Allen key.

Step 4: Install Cylinder (If Applicable)

Insert the key cylinder into the designated slot. Secure with the cylinder screw from the door edge.

Step 5: Mount Strike Plate

Align with the latch mechanism and secure the strike plate to the door frame.

Important Tips

• Always double-check measurements before drilling.
• Use a level for consistent handle alignment across multiple units.
• If unfamiliar with mortice installation, consult a locksmith or professional.
• Ensure all moving parts operate smoothly before tightening screws.
• Dummy handles are for decorative or pull-only use — they do not engage latches or locks.
