Howell Lateral-Heel Test Fixture (Optional)


Howell Lateral-Heel Test Fixture (sm)*        

Available now !


Optional — though suggested.

     Mostly for ski shops — but also available for skiers — this is a special bench-mounted test-fixture that assists with functional-inspection of a complete ski-boot-binding-system for ACL-friendly lateral-heel release uniquely specified for Howell SkiBindings.  Specially-tuned lateral-heel release limits abduction-moment loading associated with ACL, MCL and meniscus integrity.  See Menu —> Tech Info —> Release —> Part-2.  See ALL 4 photos, above.  

     Other items needed to validate Howell-specified lateral-heel release-function:  (1) only Howell SkiBindings;  (2) tape-measure (not included with purchase);  (3) calibrated torsional release torque setting**;  (4) sturdy workbench;  and (5) Howell SkiBindings lateral-heel release-setting specifications for the location on the aft-half of the ski to mark the ‘Transition Point’ between lateral-toe release and lateral-heel release (specifications are included with purchase;  or see chart below).  Howell specifications provide the boundary-condition / Transition Point where lateral-forces that are applied to the medial-edge of a ski — convert from lateral-toe release to lateral-heel release.  

     The Howell Lateral-Heel Release-Test Fixture is ‘optional’ because ski shops and skiers can rely on the lateral-heel release visual indicator settings that are provided on the binding together with Howell-recommended lateral-heel release settings for each individual skier.  However, testing the function of the complete ski-boot-binding system for lateral-heel release-function is suggested and provides a means to measure the influence of the boot within the context of the complete ski-boot-binding system.  Proper corrective-action can then to resolve any out-of-spec conditions (see ‘Troubleshooting’ in Howell Owner’s Manual and/or Howell Ski Shop Operstions Manual).

     ‘Howell Lateral-Heel Release-Test Fixture’ is one-piece, solid stainless steel including a fully-integrated stainless steel 'foot'.  Additional stainless-steel sailing hardware and non-stretch (2,000 pound test) high-tech sailing rope is included and pre-assembled with the metal-fixture — to rigidly-secure any ski boot — alpine, AT, or Telemark.  Four (4) stainless steel bolts are included to mount the fixture to a sturdy workbench or ski-tuning bench.  Workbench is not included.

     Lifetime Limited Warranty.

     This is a robust test-fixture for validation, calibration, and/or demonstration of the special lateral-heel release function unique to Howell SkiBindings.  The fixture is optional — but suggested — for Howell SkiBindings.

Howell SkiBindings is against (a) ski waist widths greater than 90mm  AND  (b) all 'pin-binding's' (except Trab TR2 and Shift) — due to their association with a new type of skiing-injury:  severe, high-energy tibia-plateau and tibial-tuberosity fractures.  Both new types of skiing injuries are the fastest-growing categories of injuries in skiing — matching the growth of fat-skis and pin-bindings.  The high-energy nature of the new types of skiing fractures involve multiple-fragments, difficult surgical reconstruction, and 10 to 15-months of aggressive rehabilitation.  Fat skis on firm snow and/or pin-bindings are a serious problem for the sustainability of our beautiful sport.  ‘Pin-bindings’ are hardly “tech”.
