6.2. HOLLOW METAL DOOR PREPARATION
The bar should be mounted to the door using the blind nuts and screws provided as shown in
Figure 6. Use the following step-by-step instructions and Figure 5 for the installation of the
blind nuts:
a. Drill the four (4) 3/8” [9.5mm] diameter holes through the interior (mounting) surface of the
door at the previously marked hole locations. DO NOT drill completely through the door.
b. Insert one blind nut assembled to the installation tool into a mounting hole.
c. While holding the collapsing nut of the tool with a 1/2” box-end wrench, turn the socket head
cap screw using a 3/16” (or 5mm) hex wrench. Note: Maintain firm pressure toward the
mounting surface while collapsing the nut.
d. Once the blind nut is adequately collapsed, remove the tool from the installed nut by backing
the cap screw out of the blind nut.
e. Install all blind nuts by using the collapsing tool and repeating the previous steps.
f. After all blind nuts are installed, hold the bar in place over the blind nuts and secure into
place with the *plastic washers and mounting screws provided.
*THE PLASTIC WASHERS MUST BE INSTALLED UNDER THE SCREW HEADS FOR THE
DSB TO FUNCTION PROPERLY. ALSO ENSURE THAT THERE IS 1/32” CLEARANCE
BETWEEN EACH BAR END CAP AND THE INNER FLANGE OF THE BASE MOUNT BEFORE
FINAL TIGHTENING OF THE MOUNTING SCREWS.

6.3. SOLID WOOD DOOR PREPARATION:

screws with a hex head are recommended (see Figure 6).
