SquarePlug SPS4BK: the smallest soldered 1/4″ straight connector with strain relief created to date! SPS4BK has been designed with the same idea in mind as for the SP400  series, that is, create the least obtrusive, yet full-featured straight 1/4″ jack. A two-screw cable clamping solution sets the SPS4BK apart from its counterparts, as it yields a much more effective strain relief action compared to what the traditional cable clamping way provides
Fits cables up to 4.8mm OD.
This connector type is ideally suited for making patch cables using Van Damme Pro Grade Unbalanced Pro-Patch Cable.
