These are bigger than the BPL micro-tensioners.
The BPL micro-tensioners are the mini Line-Loks for line diameters of 1 mm to 2 mm.
The mini Line-Loks only appear to be available in black or white. No glow in the dark colors.
Sorry if I mislead anybody on that.
At least now it is possible to order the mini Line-Loks direct instead of having to go through 2 more distribution layers.
