These sleeves are perfect when wanting to lock a centre trolling bird in to position on either stainless or titanium bars. Simply use one either side of the bird and crimp into position leaving around 1mm between the bird and the crimped sleeve.  If rigging a Carlson Ultimate Trolling Bird we suggest using  2 stainless steel washers between the bird and each lock sleeve.
 
 
We also do a 3mm or 4mm Bird Bar Rigging kit available here with everything that you need.
 
Available in two sizes  3.3mm ID and 4.2mm ID to suit the most widely used bar diameters.
