Rolls Superglide curtain track brackets used on both the hand and cord drawn versions of the Rolls Superglide tracks.
NOTE sold in quantities of 1 pair, photo for illustration.
There have been a couple of versions of the Rolls Superglide track profits. Both are metal with ridges on the front. These new version brackets do work on the older tracks, though not perfectly I’d recommend you consider a new track if you have the old type, a photo of the bracket below
The old brackets work by clamping onto the profile, secured by a screw. The new ones use a lever to push open jaws which secure into the track profile.
