What You’ll Need

  • Pencil
  • Level
  • Screwdriver
  • Measuring tape
  • Drill
  • 1/16" drill bit

In the Box

  • Blind
  • Box mounting brackets or hidden mounting brackets
  • Hex head screws (two per bracket)
  • Wand
  • Valance and clips (optional)
  • Spacer block for 1" or 2" blinds (optional)
  • Hold-down brackets (optional)

Before you begin

  1. Read all the instructions before you start.

  2. Check your package: optional items are included only if you selected them with your order, and you can install the blind without them.

  3. Choose the right fasteners for your mounting surface: the included No. 6 hex head screws for wood, wall anchors or expansion bolts for drywall or plaster, and sheet metal screws for metal (anchors, bolts and metal screws are not provided).

  4. Your order includes the right number of brackets for your blind's width. Their number and placement are the same for an inside or an outside mount.

  5. Mount the brackets level so the blind works correctly; use shims to adjust and align them if needed.

  • 1" box brackets, up to 60" wide: 2 box brackets, plus 1 support bracket over 60 sq ft
  • 1" box brackets, 60 1/8" to 120" wide: 2 box brackets and 1 support bracket, or 2 support brackets over 60 sq ft
  • 1" hidden brackets, up to 60" wide: 2 brackets, or 3 over 60 sq ft
  • 1" hidden brackets, 60 1/8" to 120" wide: 3 brackets, or 4 over 60 sq ft
  • 2" box brackets: 2 box brackets up to 48" wide; plus 1 support bracket from 48 1/8" to 84"; plus 2 from 84 1/8" to 120"

Check the mounting depth

Before marking the brackets, check the depth you need so the blind clears obstructions such as window cranks or handles.

  1. Hold the blind where you want it and mark its edges: inside the frame for an inside mount, on the wall or trim around it for an outside mount.

  • 1" with hidden brackets: 7/8" minimum inside depth, 1 3/4" for a flush inside mount (2 1/4" with valance), 5/8" on the wall for an outside mount
  • 1" with box brackets: 1" minimum inside depth, 1 3/4" for a flush inside mount (2 1/4" with valance), 1 3/8" on the wall for an outside mount
  • 2" with box brackets and valance: 1 1/8" minimum inside depth, 2 7/8" for a flush inside mount, 1 3/4" on the wall for an outside mount

Mount the box brackets (1" and 2")

  1. Position the box brackets at each end of the headrail to confirm the dimension.

  2. Mark the two mounting holes for each bracket, making sure they are square and equally spaced. Inside the frame, box brackets can be marked for top, back or side attachment; outside the frame, only for back attachment.

  3. Center any support brackets included between the box brackets and mark their holes.

  4. Pre-drill the marked holes with a 1/16" drill bit.

  5. Hold each bracket in place and secure it with two screws. Use the same holes on every bracket so the blind stands out evenly from the surface.

  • On an outside mount into drywall, use drywall anchors (not provided). A blind that is not properly anchored could fall and cause injury.

Add spacer blocks (optional, outside mount)

If you ordered spacer blocks, they give an outside mount an extra 3/8" of clearance.

  1. Attach a spacer block to each installation bracket with the 2 screws provided with each spacer.

  • Never use more than one spacer block per bracket: it could cause the blind to fall and cause injury.

Hang the blind in the box brackets

  1. Line up the headrail with the brackets, tilt mechanism facing out.

  2. Slide the headrail straight back into the brackets.

  3. If the headrail slides from side to side in the box brackets, bend out the tabs on the ends of the headrail with a flat-head screwdriver until it is snug.

  4. If you have center support brackets, hook the front edge of the headrail into them.

  5. Lower the front of each box bracket and press until the locking tab clicks.

  • Make sure the brackets and headrail are properly secured before you operate the blind, or it could fall and cause injury.

Mount with hidden brackets (1" only)

  1. Mark the bracket locations no more than 1/4" from each end cap, evenly spaced and aligned, and never directly over the string ladders or the tilter.

  2. Drill pilot holes and secure the brackets with the supplied screws.

  3. Insert the front of the headrail into the brackets first, with its front lip caught on the edge of the white part of each bracket.

  4. Rotate the back of the headrail up behind the rear leg of the brackets until you hear it engage, then pull the headrail down to make sure it is secure.

Attach the wand

  1. 1" blinds: pull the plastic sleeve up off the wand to expose the metal hook in its open position.

  2. 1" blinds: slide the sleeve over the metal shaft sticking out of the headrail and, holding it above the shaft's hole, put the wand's hook through the hole until the shaft rests in the bend of the hook.

  3. 1" blinds: slide the sleeve back down over the hook to close it. For extra clearance when you turn the wand, fit the included wand extender between the hook and the shaft.

  4. 2" blinds: hook the loop at the top of the wand onto the hook under the headrail, then let the wand hang straight down.

Install the valance (optional)

  1. If your valance was ordered with returns, bend the channel valance at the score on its back before attaching it.

  2. 1" blinds (double-slat channel valance): attach a valance clip 2" from each end of the headrail, and space any more clips evenly between them, no more than 36" apart.

  3. 2" blinds (single-slat channel valance): the slats come already in the channel. Attach the clips to the headrail, then the channel valance to the clips.

  • Keep the valance clips clear of any working parts.

Attach hold-down brackets (optional)

Ideal for doors, hold-down brackets keep the blind from swaying.

  1. Screw a hold-down bracket at each side of the bottom rail: on the sill or frame for an inside mount, on the wall for an outside mount.

  2. Fit the ends of the bottom rail into the hold-down brackets.

Operate the blind

  1. Tilt the slats: turn the wand to the angle you want. Tilt the slats open before raising or lowering the blind.

  2. 1" blinds: hold the bottom rail with both hands and lift or lower it to the height you want.

  3. 2" blinds: to raise, hold the bottom rail near the center, press the center button with your thumb and lift, balancing the rail with your other hand; let the slats stack evenly, hold the rail still at the height you want and release the button.

  4. 2" blinds: to lower, press and hold the center button as you pull the bottom rail down, then release it at the height you want.

  • Inside mount: pull the bottom rail slightly toward you before raising it, then set the blind back into the window opening at the height you want.
  • Inside mount: to lower it completely, pull the bottom rail down and slightly toward you, about 1" past the sill.

Remove the blind

  1. Box brackets: raise the blind fully, then unlock and lift the front clip of each end bracket and slide the headrail out. With center support brackets, lift the front of the headrail clear of their channel and slide it out forward.

  2. Hidden brackets: push and tilt the headrail down to release it from the brackets.
