How to Install Horizontal Blinds

Once you ensure that all necessary parts are account for, it is time to install the brackets that will hold secure the blind to the window frame or wall, depending on your preference and order. Horizontal blinds include wood blinds, faux wood blinds, mini and aluminum blinds.

Unwrap the blind, but leave all cords tied. This will make it easier to work with the blind.

Two brackets, both right and left, are supplied with each blind. These brackets are used for all types of mounting (outside, inside, ceiling). Bracket hinges must face inside the room. This is where you will slide in the headrail and snap the doors closed.

Depending on blind placement, it may be necessary to use plugs or anchors before using screws. Center support brackets may also be included to provide additional support on wider blinds. Center support brackets should be spread evenly along width of the blind. These brackets should not interfere with the cord or ladder. Be sure all brackets are level.

Inside Mount

Make sure that your blind is the proper width. Holding the headrail level, slide it inside the window frame to the desired position. There should be between 1/4" and 1/2" of clearance on each side of the blind. This will allow room for the mounting brackets, and to allow the blind to raise and lower properly. Holding the headrail in place (and making sure it is level), mark on the window frame the bottom of the headrail. This will be your reference point or positioning the brackets. Hold the brackets to the frame at your reference point and make additional pencil marks through the screw holes to determine exactly where the bracket will be attached. Select diagonal holes (right top-left bottom) to assure a secure installation. Depending on your window frame material, it may be necessary to pre-drill the screw holes or use wall anchors so that the screws can be attached with ease. Do this step for both the right and left brackets. If center support brackets are used, place evenly along width of blind. Position each bracket and mark holes with a pencil. Insert and tighten screws through all brackets, making sure all brackets are straight and level, and the screws are flush with the bracket.

Outside Mount

With the blind in the lowered position, hold up to wall in the position you want it to hang. Make sure the blind is centered and level. Mark with a pencil a small mark below the headrail at each end, also mark 1/4" past the end of each headrail. Place end brackets inside pencil marks and mark screw hole positions in rear of bracket in a diagonal pattern. If center support brackets are used, place evenly along width of area blind is to be mounted and mark screw holes. Insert and tighten screw through all brackets, making sure all brackets are straight and level.

Attach the Valance, Depending on the Type

Snap the valance clips over the front lip of the headrail before mounting the blind to the installation brackets. A valance clip is furnished for every ladder. Install the valance clip next to each ladder. If the clips are mounted directly in line with the ladders, they may catch on the cords inside the headrail. Snap valance into place. For mini and aluminum blinds, we reccomend you slide each slat in from the side to prevent the risk of crimping the slat.

Hold Down Brackets (optional, and reccomended for doors only)

Note: Not recommended for single control blinds. Recommended for OB mount blinds (ie: door installation) Hold down brackets are used to keep the bottom of the blind from swaying and were supplied if requested when ordering the blind. Some blinds have bottomrail end caps with a hole in the center; on these blinds, push a hold down pin into the hole in the end caps.
  • Lower blind completely ensuring that the bottomrail is level
  • Place hold down brackets on bottomrail hold down pins
  • Mark bracket location on window frame or door
  • Remove hold down brackets and raise blind
  • Drill holes for bracket screws and mount brackets
  • To secure bottomrail snap pins into slotted brackets
