Leki Expander

18 mm replacement expanders for older LEKI trekking poles with twist-lock mechanism and red standard expanders. Standard expanders come in three sizes 18 mm, 16 mm and 14 mm. If your poles sections have a diameter of 18, 16 and 14 mm (usually poles that can extend to 145 cm) you would need the 18 mm expander to lock the upper connection and a 16 mm expander for the lower connection). If your pole sections have 16, 14 and 12 mm diameters (usually poles that go up to 135 cm) you would need 16 mm expanders for the upper and 14 mm expanders for the lower connection. Standard expanders do not fit on SLS twist-lock pole models (black, blue or gereen expanders). Sold in pairs.
