What is IN THE BOX

Extends from 3.5 to 5 inches
The arm slides out of the wall plate, so one set works over a flat wall, window trim or a deep sill.
How far it reachesA third bracket for the middle
On a wide window, the center bracket keeps a long rod from bowing between the ends.
Why threeScrews hidden on all three
Each bracket has a magnetic cover over its wall plate, the center one too.

How Far These Extendable Curtain Rod Brackets Reach
Each bracket has a two-part arm. One part is fixed to the wall plate. The other carries the cradle and slides along a slot. Loosen the two screws on top, pull the cradle out to the depth you need and tighten them. The range is 3.5 to 5 inches from the wall.
That 1.5 inches of travel lets you pick the depth after you see the window.

Use the full 5 inches when something sticks out
Window trim, a deep sill or a blind headrail all push the curtain away from the wall. Extend the arms until the fabric hangs clear of them. On a flat wall with nothing in the way, keep the arms short and the curtain sits closer to the glass.
Check your window with the slider.
If you need more than 5 inches, the 6-inch heavy duty curtain rod brackets go further. If you want the rod almost flat to the wall or on the ceiling, use the ceiling curtain rod brackets with a 3-inch profile.
Fits your window?
3.5–5 in from the wall. Three brackets with magnetic covers included.
Wide Windows: Why the Third Bracket
A rod held only at its ends bends most in the middle. The longer the rod and the heavier the curtains, the more you see it. A center bracket cuts the free span in half, so the rod stays level across a wide window.

Where the center bracket goes
Put it halfway between the two end brackets, at the same height. Hang one curtain panel on each side of it: rings and grommets can’t slide past a bracket. Set the center arm to the same depth as the end arms, or the rod won’t run straight.
Black on a Wide Window

One color from end to end
Across a wide window, the rod is the longest line on the wall. Black hardware turns that line into a frame: rod, brackets and covers in one color, with nothing silver at the joints. It works over a big living room or bedroom window with floor-length curtains in white, oatmeal or gray.

Three brackets: two ends and a center
Place the end brackets a few inches past each side of the window frame so open curtains stack beside the glass. The third bracket goes in the middle. If you only want the magnetic look on a standard window, the magnetic curtain rod brackets in a set of 2 are the same bracket without the center one.

FAQ
Depth, the center bracket and hanging curtains on a wide window.
How far do the brackets extend?
From 3.5 to 5 inches from the wall. Loosen the two screws on the arm, slide the cradle in or out and tighten them. You can change the depth later without taking the brackets off the wall.
Do I have to use all three brackets?
No. On a short rod with light curtains, the two end brackets can do the job. Add the third one when the rod spans a wide window or the curtains are heavy enough to bow it.
Do all three brackets need the same projection?
Yes. If the center arm is shorter or longer than the end arms, the rod bends toward or away from the wall. Set all three before you mount them.
Can one curtain panel slide across the center bracket?
No. Rings and grommets stop at the bracket. With three brackets, hang a pair of panels, one on each side of the center.
Can I buy these brackets in bulk?
Yes. Trade pricing starts at one master carton per finish, 30 or 50 units depending on the model, with discounts from 20% off retail that grow with volume. In-stock orders ship from our Pennsylvania warehouse within one business day. See partner pricing or email [email protected].
