Wall Conditions and Tools Suggestion
Most of the drywall will have corner bead in steel or vinyl; it’s strongly recommended to use a Hole Saw to cut the holes for
installing locks and trim plates. Hole Saw for steel will also help cut through any screws inside drywall or wood stud to make
the installation job run faster.

Note: While door is fully closed, measure overlap on side
where lock is to be installed. For casing less than 1 5/8 in
[41.2 mm], door overlap must be at least 3 in [76.2 mm].
Align strike with lock.
Note: If lock bore center location is 2.125 in [53.9 mm] or
more from edge of opening, use stud finder to ensure there
are at least two studs stacked behind lock bore center.
Extended spindle and fixing screws may be required.
Contact KN Crowder to order an extension kit.
Step #2:
Verify wall thickness is
minimum 4.5 in [114.3 mm]
thick for KNC’s C-54BL
ADA barn door lock. There
is no maximum thickness
minimum stud size: 2x4,
backset: 2.25 in [57.1 mm]

Installation Steps
For drywall opening with 0.5 in [12.7 mm] drywall (gypsum
board), minimum 2 in [50.8 mm] door overlap is needed to
install C-54BL. The lock bore center must be at least 1 in
[25.4 mm] from wall edge; align strike with lock.
Choose center hole location based on aesthetic
preference; must be at least 1 in [25.4 mm] from the edge.
Choose center hole
location based on your
aesthetic preference, must
be at least 1 in [25.4 mm]
from the edge.
Do not install lock on casing that is less than 1 5/8 in
[41.2 mm] wide. Drill lock bore at least 2.25 in [57.1 mm]
from edge. For this type of installation, door overlap must
be at least 3 in [76.2 mm]. Align strike with lock.

Step #1:

Step #4:
Before drilling, cover area around the bore hole with
masking tape to prevent the drywall from chipping or
cracking. With a Ø2 1/8 in hole saw, drill on jamb side in
accordance with following steps.
Without casing:
A. Drill through drywall approximately 0.5 in [12.7 mm] to
locate first wood stud.
B. Continue drilling 1 in [25.4 mm] into the stud.
Note: Do not exceed depth of wood stud when drilling. Minimum 0.25 in [6.3 mm] or thicker wood backing is required to support the lock.
For drywall openings protected with steel corner beads, use metal hole saw for cleaner and faster installation.
With casing 1 5/8 in [41.2 mm] or wider:
A. Drill through casing and drywall approximately 1 in
[25.4 mm] to locate the first wood stud.
B. Continue drilling 1 in [25.4 mm] deep into stud.
With casing less than 1 5/8 in [41.2 mm]:
A. Drill through casing and drywall approximately 1 in
[25.4 mm] deep to locate the first wood stud.
B. Continue drilling 1.75 in [44.5 mm] deep into the stud.
This will give you a 2.25 in [57.1 mm] deep bore to
accommodate the lock installed next to casing.
Step #5:
Double check lock bore distance from Step 1. Refer to template markings to ensure both lock and strike pilot holes are within door overlap requirements. Keep 0.375 in [9.5 mm] safety
margin to edges.
Moulded casing with uneven surface:
At pilot center mark, use Ø1 1/4 in hole saw to drill to a depth of 0.375 in [9.5 mm]. Use
Ø1 in hole saw at same center mark to drill hole to correct bore hole depth.
Note: Do not drill too deep, you may damage the wall on the other side.

Drywall or flat casing openings:
Use a 1 in [25.4 mm] hole saw to cut lock bore hole to
depth as shown in chart.
Note: Hole saw for metal should be used for drywall with
steel corner bead.
Note: If there is a gap between the drywall and the stud,
measure the distance and add to the bore hole depth. Hole
depth must accommodate lock barrel preparation in step 6.
You can deepen trim bore as needed after that step.

Step #6:
For drywall and casing less than 1 5/8 in [41.2 mm]:
A. Insert bracket into trim bore
B. Insert lock bolt into lock bore and fit into bracket slot.
For moulded casing with uneven surface:
A. Insert 0.25 in [6.3 mm] spacer provided with lock into
the 1.25 in [31.7 mm] recess first.
B. Insert bracket into trim bore.
C. Insert lock bolt and spacer into lock bore and fit
into bracket slot.
Step #7:
Ensure spindle hub is at center of trim bore. Use spindle or screwdriver to test bolt
retraction; if not smooth, troubleshoot as follows:
1. Check 2 1/8 in [53.9 mm] trim bore dimensions.
2. Ensure hole is free of debris.
3. Make sure 1 in [25.4 mm] lock bore is perpendicular to trim bore.
4. Check lock by removing it from bore and throwing the bolt. Adjust wall prep as needed.
Step #8:
Fasten the two wood screws inside the trim bore hole through lock body and into wood
stud.

Step #14:
With the pilot hole as a guide, use a Ø1/4 in bit to drill a
hole from the outside to connect with the strike bore hole.
Note: Standard barn door to wall clearance is approximately 0.375 in [9.5 mm] to 0.5 in
[12.7 mm]. Install additional spacer as needed behind the strike faceplate if the door to wall
clearance is over 0.5 in [12.7 mm]. Additional spacers can support maximum clearance of
0.75 in [19 mm] between door and wall.
Step #13:
Using the strike center position as a guide, drill a pilot hole
through the door with a Ø1/8 in drill bit from strike side.
With the pilot hole as guide, use a Ø1 in hole saw to drill a
1.25 in [31.7 mm] deep hole.
Note: do not drill through the door!

Cut spindle and screw to accommodate wall side backset.

test lock bolt movement.
Step #11:
Fasten trim screws until
trim is tight to jamb
surface.
Note: do not over tighten.
Step #12:
Move door to closed
position and throw the
lock bolt to mark the exact
strike center position.
This location must be a
minimum of 1 in [25.4 mm]
