Howell Lateral-Heel-Release Test-Fixture (Optional)
Howell Lateral-Heel-Release Test-Fixture (sm)*
Available now !
Optional — though suggested.
Mostly for ski shops — and available for skiers — this is a special, optional, bench-mounted test-fixture that assists with the functional inspection of the complete ski-boot-binding system for the special lateral heel release function that is uniquely specified for Howell SkiBindings. Specially-tuned lateral heel release is associated with limiting abduction-moment loading that is related to ACL and MCL integrity. See all 4 photos, above. The only other items needed to validate Howell-specified lateral heel release function is a tape-measure (not included); a pre-existing, properly-calibrated, lateral toe release setting (or a properly calibrated torsional release torque setting)**; and Howell SkiBindings data/specifications for the special operating-range (tolerances) of the lateral heel release function (data-charts are included with purchase). Howell data charts provide the boundary-conditions where lateral forces that are applied to the medial-edge of the ski convert from lateral toe release to lateral heel release.
The fixture is ‘optional’ because ski shops and skiers can rely on the lateral heel release indicator settings provided on the binding together with Howell-recommended lateral-heel release settings. However, testing the complete ski-boot-binding system for lateral heel (abduction moment) release-function provides a means to evaluate the influence of the boot within the context of the full-set of ski equipment.
Howell Lateral-Heel Test-Fixture is 1-piece, solid stainless steel with a fully-integrated stainless steel 'foot'. ‘Includes stainless-steel sailing hardware and non-stretch (3,000 pound test) high-tech sailing lines to rigidly-secure any ski boot — alpine, AT, or Telemark. Four (4) stainless steel bolts to mount the fixture to a sturdy workbench or ski-tuning bench are included. Benches are not included.
Lifetime Limited Warranty.
This is a robust shop-test-fixture for validation, calibration, and/or demonstration of the special lateral heel release function that is unique to Howell SkiBindings. The fixture is optional for Howell SkiBinding.
FLAT-OUT SKIING CONFIDENCE.
It was inevitable.

Howell SkiBindings is against (a) ski waist widths greater than 100mm AND (b) all 'pin-binding's' (except new Trab TR2) — 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 are a serious problem for the sustainability of our beautiful sport. References: (1) Dominik Heim, MD; SITEMSH-Japan, 2016.
