Squareplug currently to my information is the shortest instrument cable available. When plugged in it protrudes about 30mm, has a 13mm diameter. The way the strain relief works is that on the connector there are 2 screws that center the whole cable inside to prevent any tension. Finnish is a matte nickel look.
Right angle connectors are low profile measures [9.7mm (0.326") Deep x 18.5mm (0.67") Wide x 28mm (1.10") Tall]
Overall diameter with sleeving is 6.8mm | Overall diameter w/o sleeving is 5.8mm
