LEKI Code: LESECL10412 mm Lower Section455 mm LengthNature/Silver AnodizedSLS (Super Lock System)16/14/12 mm SectionProduction Era: 2008–2015
The Thermolite XL, Thermolite, Corklite, and Softlite are LEKI’s aluminium SLS trekking poles from the late 2000s through to the mid-2010s — reliable, versatile poles covering everything from a day on the South Downs to multi-day routes through Snowdonia. LESECL104 is the genuine LEKI replacement lower section for this range: 12 mm in diameter, 455 mm printed length, finished in Nature/Silver anodized aluminium, and built for the SLS internal twist-lock interface. It covers the Thermolite XL, Thermolite, Corklite, and Softlite across approximately 2008 to 2015. On an SLS pole the lower section is secured by an internal twist collar, and the printed length on the tube is a precise specification that determines adjustment range and correct collar seating. LESECL104 restores the original 12 mm diameter and 455 mm printed length, ensuring the SLS mechanism locks correctly throughout the full adjustment range. The 455 mm printed length on your existing lower section is the check that matters — confirm this number before ordering, as other LEKI SLS sections with a 12 mm tip are specified to different lengths.

► Compatible Poles & Fitting Guide
LESECL104 is confirmed compatible with the following LEKI poles where identification has been established from official LEKI product records. Always verify against the 455 mm printed length and 12 mm diameter on your existing lower section — these measurements override model name matching.
✓ Thermolite XL — article codes 082133, 092133
✓ Thermolite — article codes 082136, 092136, 6312136, 6342136
✓ Corklite — article codes 082138, 092138
✓ Softlite — article codes 092188, 6312188
✓ Additional confirmed compatible article codes (model name not established from available sources): 082188, 092242, 6352188, 6352133, 6352136, 6352138, 6352132, 6332188, 6342216
✓ To fit: twist the SLS collar at the base of the middle section anti-clockwise to release. The lower section slides free. Insert LESECL104 from below, aligning it with the internal twist-lock collar. Push until fully seated, then twist clockwise until the lock engages with a firm stop. Set to your required length and confirm the lock holds under a firm pull-test before use.
✓ SLS lock check: after fitting, set the pole to mid-length and apply firm downward pressure on the tip. The section must not move. The SLS mechanism is fixed-tension — if the collar does not hold after correct fitting it requires replacement.
✓ SLS identification: rotate the collar at the joint between the lower and middle sections. SLS releases with a short anti-clockwise twist; an external lever at this joint means Speed Lock — not compatible.
► Not Compatible With
✗ Speed Lock 1 (SL1) poles — external lever clamp with different tube interface; not interchangeable with the SLS internal twist-lock system
✗ Speed Lock 2 (SL2) or Speed Lock + (SL+) poles — lever-based locking systems with incompatible section geometry
✗ SLS poles with a 14 mm lower section — LESECL104 is 12 mm; a 14 mm section will not fit the 14 mm middle section clamp collar correctly
✗ Poles whose existing lower section is not marked 455 mm — the printed length is the definitive check; any other measurement indicates a different section part is required
BEFORE YOU ORDER — FOUR-POINT CHECK
✓ Printed length: the measurement printed on your existing lower section must read 455 mm — this is the primary identifier and takes precedence over model name, colour, or purchase year
✓ Diameter: the tip end of the section must measure 12 mm — confirm with a calliper or from original product documentation
✓ Locking system: your pole must use the SLS internal twist-lock — twist the collar at the joint to release; an external lever clamp means Speed Lock, not SLS, and this section is not compatible
✓ Construction: confirm your pole is 3-section telescopic with a 16/14/12 mm section profile — the middle section should be 14 mm in diameter where it meets the lower section joint
