Sliding Block for IKEA Vidga # flush mount

I made sliding blocks for the IKEA Vidga curtain rail system which allow a direct attachment underneath the ceiling.

The sliding blocks fit into the (upper) smaller part of the profile and thigten the rail by help of a countersunk srew. To get accses to the scew's interface, the profile has to be drilled to get a hole with at least the diameter of your tool or better with the diameter of the screw head.
Beneath a short block I designed a longer version with two mounting holes in a distance
