I called KBC Tools and they do have blue and orange in stock and can order in black for me. Thanks.

Ya, KBC is where I got mine for my milling machine. Good place to deal with

JL Aquatics also have 1/2 and 3/4 lineloc available.

I've purchased my lineloc parts from them to build my returns.

Thanks. I've seen the larger locline at OA and also J&L but I need smaller 1/4 inch for an AIO pico tank I'm building. KBC has ordered some for me and hopefully they'll have it in soon.

I remember seeing some on a Delta scroll saw for blowing the dust away.It was black in colour.Maybe you could look at a place that carries tools and see if it is usable and if it could be ordered in as a replacement part.
