When choosing Matrix swivels and clips, first decide whether you need a rotating connection, quick release or sliding feeder attachment. Product names can sound similar while the parts perform different jobs.
A swivel rotates; a clip allows quick changes
A Hooklength Swivel or Barrel Swivel provides a rotating connection. To remove a hooklength or feeder without retying, consider Snap Links & Sleeves or Snap Link Swivels. With a sleeve, check the clearance around the connection so the complete assembly suits your rig.
Match the feeder clip to the feeder
Feeder Snap Links have a bead that allows the attachment to slide along the line. The X-Strong version is intended for heavier feeders. Pellet wagglers require the corresponding Pellet Waggler Attachments with line stops. Choose by function and load, then match the size to the rest of the rig.
