This clamp contracts the external paddle shaft around the internal shaft (spigot) so needs a slot or slit in the paddle to allow the paddle shaft to move and grip the smaller shaft inside. The entire Clamp is on the outside of the paddle shaft and one consistent diameter, There is no overlap to the spigot. You will normally sand your paddle shaft slightly to ensure adhesion so there is less need for accuracy with dimensions but this clamp will fit around 28.5 mm external diameter paddle shafts Approx 3 cm long Diameter Ø: fits shafts of 28.5mm (approx) Typically this is glued into place and we use a good quality 2 part epoxy but with care it could be used without glue or a different (ensure the gap in the clamp lines up with the slot when in use) MPN: 8050070 UPC: 840380501601
