Mainsail slugs or slides

[BrickBridge]

I use the same stops Justin mentioned a few posts above mine. Got them from Amazon.

I got the round sail stop.  I don't remember if it was 3/8 or 1/2".  I did have to grind it down a little to make it fit in the slide.

This is the sail stop I am using. I ordered three. I use two and have one backup. One just holds the boom up before I bend on the main. The other performs the function of keeping the main from sliding out of the track after installation when it's not hauled up. https://www.amazon.com/dp/B00LAHBEWU/ref=cm_sw_r_sms_c_api_kKiqAb01MSTCN
