Leki Pole End Sleeve - Smooth Version Genuine spare / replacement. Sleeve to cover the join between the pole sections. Helps to prevent dirt and debris from entering the shafts. The sleeve also reduces the noise of the sections rattling against each other and covers the end of the section to prevent injury. Old worn out sleeves can easily be pulled of by hand with the replacement being a simple push fit. Sleeves come in three sizes depending on the type of pole and which section it is for. Note: A ridged version was supplied on new poles until about 2005 which is now becoming hard to source. These smooth Sleeves fit just the same and are a bit stronger. The sleeves fit the following pole diameters: Small: 14mm  /  0.55in Medium: 16mm  /  0.63in Large: 18mm  /  0.70in In most cases: If your poles go up to 140 or 145cm (55 or 57in) you will need the 18 mm sleeves for the upper shaft and 16 mm sleeves for the middle shaft. If your poles go up to 130 or 135 cm (51 or 53.15in) you will need 16 mm sleeves for the upper shaft and 14 mm sleeves for the middle shaft. If you need help finding the right size please contact us.
