These are an alternative clip for @LineArcLine's excellent Skadis T-Clip System. This version shortens the clip so that it does not protrude beyond its mounting recess and will not interfere with anything in front of it. Both painted and unpainted versions are included.
You may or may not be able to turn this version with your fingers, but carefully turning the clip with a pair of pliers should be no problem if needed. While I have not tested this version for strength compared the original, I expect it to be somewhat less resilient than a standard T-Clip. So please proceed with caution if you intend to apply heavy load or if the feature will be subject to frequent shocks. These trade-offs make this version a little less convenient than the original, but I felt most people would find value in this option on certain applications.
