(222) Perko Large Threaded Collar [3DOTS: tight on YOLOtek gear ONLY]

The NEW & IMPROVED G4 Locking Collar has been rebuilt from the ground up. Over 50% stronger than the 00-Original Locking Collars. It Will fit PowerStick-53" & PowerStick-20", so if you need a replacement this is it.

If you own a PowerStick-53" Gen1 or Gen2, this is a MUST HAVE to replace your existing 00-Original.

Compare to your navigation light base and make sure it says Perko.

If you are looking for a collar for your white running/anchor light, this will NOT fit. Click here for link to Perko Large Thread for your white running/anchor light. Any questions, please call us 800-488-5512
