How to Install Custom Vertical Blinds


Before you begin your installation:

Read all installation instructions!

  • Make sure that you have all tools and hardware needed for installation.
  • Check the installation surface (wall, ceiling, or window frame) to ensure that you have suitable fasteners and tools for the material.
  • Double check the headrail and blinds for proper width and length. If you are installing several sets of blinds, be sure to match them with the appropriate window.
  • Check the parts list shipped with the product to confirm that you have the correct number of brackets.

Tools You May Need (not included):

  • Tape Measure
  • Level
  • Pencil
  • 3/8" Wrench
  • Flat-blade or Philips Head Screwdriver
  • 1/4" Nutdriver
  • Drill with Bits
  • Drywall Anchors
  • Safety glasses
  • Scissors or Utility Knife
  • Ladder

Optional Brackets:


Extension Brackets

(Offers clearance for obstructions) Outside-mounting extension brackets will provide 1"–3" clearance between the headrail and mounting surface. Assemble extension bracket as shown.


Step 1

Mounting Brackets

Outside Mount Bracket

Inside Mount Bracket

Headrail with vane carrier


Step 1A

Mark the bracket locations - outside-mount installation

  • Position one bracket at each end of the headrail, 3" in from the ends.
  • Space any remaining brackets evenly, not more than 30" apart.
  • Mark the bracket mounting hole locations at the desired height, making sure they are level and square. Allow at least 1/2" clearance for vanes above the floor or sill.

Step 2A

Install the brackets - outside-mount installation

  • If mounting into drywall or plaster, use 3/16" drill bit and insert wall anchors before inserting screws.

Step 1B

Mark the bracket locations— inside-mount installation

  • Position one bracket at each end of the headrail, 3" in from the ends.
  • Space any remaining brackets evenly, not more than 30" apart.
  • Mark the bracket locations, making sure they are in a straight line that is parallel to the wall.

Determining the correct distance from the wall or window:

  • Position the center of the brackets a minimum of 2-1/2" in front of the window frame or any protruding trim or handles.

Step 2B

Install the brackets— inside-mount installation

  • Install in a wood window frame using the included screws.


For models equipped with a valance, the valance mounting clips should be installed to the headrail at this time. Please refer to the installation instructions included with your valance before proceeding


Step 3

Attach the headrail — outside- or inside-mount

  • NOTE: For wide windows and sliding glass doors, two people are recommended for installing the headrail.
  • With the bracket positioned as shown, fit the top front lip of the headrail into the front part of the spring clip.
  • Tip the back of the headrail up into the spring clip until it locks with a clicking sound.

Step 4

Center the Vane Rotation

Models With Wand

  • Attach the wand.
  • Rotate the wand so that the vane clips are at a right angle to the window.

Models with Vane-Rotation Chains

  • Adjust the vane-rotation chain so that it is centered (ends of chain should be even). Vane clips should be at a right angle to the window (open position).

Step 5

Attach the vanes

  • Starting at one end, align the rectangular hole in the vane with the clip.
  • Slide the vane fully into the clip; then pull down slightly to lock the hook on the clip into place. Repeat for the remaining vanes, making sure that all vanes are facing in the same direction.
  • Left Image - Vanes nest correctly for optimum light control.
  • Right Image - Vanes nest incorrectly, preventing optimum light control.





  • Bottom Chains (if ordered)
  • Connect the vanes together with the included clips and chain.

Step 6

Attach the tension device (cord/chain control only)

Refer to instructions in the hold-down tension device.


Step 7

Test the Vane Rotation

Turn the wand or pull the bead chain in alternate directions to ensure that the vanes rotate smoothly in both directions.


Step 8

Test the Traverse

With the vanes in the open position (vanes at a right angle to the window), slide the wand or pull the cord in alternate directions to ensure that the vanes move smoothly in both directions.



Please refer to the valance instructions for your valance style at this time to complete your installation.
